Top 5 Signs your Water Heater is Going to Explode

When it comes to the water heaters of the house, a little maintenance is enough for the long run. But, without maintenance, your water heater can show various problems and sometimes things might not be in your favor, and your water heater might explode. Therefore, it is essential to know the signs your water heater is going to explode.

The 5 Signs Your Water Heater is Going to Explode

1. Lack of Hot Water

Are you getting lukewarm water while showering? Does your water heater take a long time to warm the water? Are you getting hot water from the tap immediately? If any of these symptoms are showing together or alone, your water heater lacks hot water. These are the most common signs of such a problem.

Most of the regular water heaters contain 30 to 50 gallons of the water storage tank. When the water is heated by electric source or gas, the minerals of water separate and settle at the bottom of the tank, with time, these minerals from water get accumulated at the bottom and make a barrier. This barrier works as an obstacle between the water and the burner. Therefore, enough heat cannot reach the water, and as a result, you get cold water during shower.

The more the sediment is, the harder the water heater tank needs to work for heating the water. Eventually, the water heater will either fail or explore. Even if it does not explode, it will leak and result in the costly water bill. In such a situation, you will not have any other way than replace it.

The Solution

You can solve it by scheduling annual flushing of your water heater tank. If you live in a locality of hard water, then you should invest in water conditioning to keep the water heater running at the most efficient level.

2. Pooping or Rumbling Noise

Another most common sign is the noises coming out of the heater. If you notice that your water heater is making creaking, popping or even rumbling noises then, it is right time you call the nearest plumbing company. Mineral buildup and hard water are also responsible for the sounds coming out of your water heater. A specific popping noise comes out when the mineral forms a layer on the water heater surface. This is another sign that your water heater has some issues. The sound is the result of pockets of air in the deposited sediment layer that boils along with the water in the tank.

The Solution

If the water heater is still making such noises, then this is one of the prominent signs hot water heater is failing and you need to flush out the sediment from the tank. But, if flushing out the sediment does not work then, your water heater has severe issues with the main unit. The noises coming out of the water heater is alarming, and it denotes that the heater is on the verge of burst, leak or crack. To save yourself from the high cost of replacing, it is best to see a plumbing company as soon as possible.

3. Cloudy Water

Is cloudy water coming out of your water heater? Is there a metallic scent in the water? Does the water taste funky? Funky-smelling, murky water is an important sign of failing water heater. The mineral is traveling throughout the heater and as a result, clouding-up the hot water of your tank. Again, if the water coming out of the heater is reddish or orangish then, it shows that the tank or the pipes are rusty. You need to take of this as soon as possible.

The Solution

If the rusty or the cloudy water is bothering you then, you need to replace the pipes or the tank as soon as possible. Although rusty water does not cause any health issue, with time you need to pay a large amount of money for the water heater replacement.

4. The Faulty or Leaking Pressure Relief Valve

There are two significant symptoms when it comes the pressure relief valve is the pressure life valve of your water heater is leaking? Or, does the hot water stops flowing through the valve while you are testing it? If the scenario is like any of the above then, you need to replace the water heater quickly.

The TRP valve releases the accumulated pressure in the heater when the temperature or the pressure gets severely high to prevent a possible explosion. With continuous use, the rust, corrosion, and salt will start to build up causing the valve to fail and stop functioning or results in a broken water heater.

This can cause catastrophic damage if not taken care at the right time. This will not just result in property damage but also personal injury as well.

The Solution

For testing the TRP calve, lower and raise the test lever couple of times so that it lifts the brass stem that is fastened to the valve. The hot water will then rush out from the end of the drainpipe. In case, there is no water coming out of the pipe; you need to see a professional plumber. The plumber will place the valve and make sure that there is not malfunctioning.

5. Leaking Tank Water

Is there a pool of water under the water tank? Corrosion within the water tank can cause several cracks and fractures. If not taken into account then, this can lead to water heater explosion. In some cases, it can even flood your entire home.

The Solution

If the tank leak is severe then, you need to turn off the water supply of the house immediately. This is a temporary fix. Only a plumber can help you in such situation.  So contact a plumber to fix the crack as soon as possible.

 Pro Tip:  We often don’t understand but it very important to check on your water heater at least twice a year. A lot of the plumbing companies offer affordable water heater maintenance service. You can go thru YouTube videos and check on the heater all by yourself but it is always better to take professional help.

These are the signs your water heater is going to explode. Hence, you need to contact the nearest plumbing company as soon as possible. They will quickly replace and repair the water heater before any disaster strikes.

Should I Replace My Water Heater Before It Fails?

Should I replace my water heater before it fails? It’s the most common question among the homeowners. Water heater replacement is very rare among the homeowners. In fact, most of them do not realize how important the water heater is until they get up in the morning, but instead of hot water, they find cold water coming out of the tap. The water heater does not fail in one day; it starts to give you signs from a long time. So, I should replace my water heater before it fails.

Postponing the replacing of the water heater is not good for you. The more you postpone, the more expensive the replacement will be. Sometimes, delaying the decision can create a safety hazard as well.

When Should I Replace My Water Heater Before It Fails?

How to know the signs to replace your water heater? Here are the clues that will help to identify the problems with your water heater.

1. The Age of the Water Heater

If the water heater of your house is a decade old, yet it works fine, then you must be thinking how long it will last. The truth is, with reasonable use along with proper maintenance, the water heaters may last up to 20 years. But, when the water heater exceeds the expected service life, then it starts its journey towards failing.

Therefore, when your water heater is already 8 or 12 years old, then you already know that water heater replacement in the future.

Some homeowners choose to replace their current one whereas, some wait for the existing heater to fail. Look out for the issues, if the water heater is making noises or is not working correctly or using up too much electricity or gas to run then, yes, it is time you should replace your water heater.

Replacing the water heater is not just inexpensive, but it is also safe for the people living in the house. Some even buy the water heater leak detector to save you from the massive leak.

2. The Signs of Rust

Rust is one of the most important signs that your water heater needs to be replaced. The rust mainly accumulates along the temperature and pressure relief valve and can also be found in the outlet and inlet connections. When the water coming out of the tap is brownish or reddish in color then, rust is in your water heater and this is one of the signs hot water heater is failing.

Most of the water heater tank is made of steel, and they are prone to corrosion and rust. The anode rod in the heater is built to sacrifice itself and protect the water heater tank. However, with time all the tanks rust and leak.

You can flush the water heater periodically for removing the buildup, but there is no direct solution of treating the rusted pipes and tank. You can call the professional plumber to replace the water heater tank.

3. The Clogged Drain Valve

The valves of the drain can clog while you are trying to remove the sediment buildup. You can decrease the sediment by installing an incoming water filter. Sometimes the rust also causes the drain valve clog.

As a part of your regular water heater maintenance, you should flush your water heater. If you do not regularly flush then, with time the interior of the tank will breakdown, this will not just cause leakage but also block the drain valve of the drain.

The drain valve is spout found along the water heater bottom. It is designed in such a so that, it can drain the water from the water tank for the repairs and also the cleaning of mineral buildup and flushing sediment.

Well, if you are using a gas-filled water heater, the heater will make a popping sound if sediment starts to build up. Electric units also negatively affected by the water heater. If not taken proper measures, the water heater will break and begin to leak. This leakage can flood your entire house and basement.

4. Cold or Lukewarm Water

When the hot water does not feel hot anymore, there is a good chance that the problem is the electric thermostat or the heating element. Over time, the parts of the heater do not work well as they used to before. Sometimes the parts of the heater stop work working together. For this reason, the water heater gives our cold or lukewarm water.

The broken dip tube also causes lukewarm water. When the dip tube is broken, the hot water of the tank will be diluted by the incoming cold water resulting in lukewarm water.

Sometimes, cold or lukewarm water comes out of the water heater even if there is no problem. You just merely outgrew the water heater, and you need to replace it as soon as possible — the demand for hot water changes with time. Sometimes, your water heater is not able to keep up with the growing demand for the water heater and you are left with cold or lukewarm water.

In such a case, all you need to do is, call a plumber and tell him to check the water heater. If he finds out any major problem, then it is better to repair it as soon as possible. If the heater is unable to keep up with the rising demand of hot water of your family, then, you need to replace it will a larger one ASAP.

Replacing the Water Heater!

Consult a professional if you want to repair the broken water heater. Sometimes repairing does not do much help. Before replacing the water here are a few things that you should consider:

  • Will you change the set-up of the water heater?
  • Will you buy a tank-less water heater?
  • Does the size of the current heater is enough to meet your household water requirements?
  • Will you replace it by yourself or call a professional?
  • If you are installing the heater yourself, how are you going to dispose of the old one?

Should I replace my water heater before it fails? If your water heater is showing any of the above-mentioned symptoms then, of course, you should. Using DIY technique for replacing water heater sometimes can go wrong. If you think the water heater is not working correctly then, you should consult a plumber first. Sometimes a failing water heater can be de dangerous for your family. Therefore, it is essential to replace the water heater and take the necessary steps immediately.

how to reset water heater

How to Reset Water Heater 2019!

The cold season is here and you are all set to have a warm and fresh bath. You have a water heater that helps you have that privilege. But what if your hot water turns lukewarm, or cold or it runs out before you’re done with your shower, who is to blame? Definitely, it’s the water heater.

Whenever such kinds of incident occur the first thing that you must do is to check the water heater so you can find out the actual problem. If the problem is with the water heater settings,

then opt for resetting it. So, to help you out, this article will highlight how to reset the water heater so you can enjoy warm water as expected!

Resetting the Water Heater

If you have the experience working with electricity only then you can follow these steps. Or else we would advise you to contact a professional.

Step 1: Disconnect the Water Heater

Have a visual inspection of the water heater conducted to check out if the reservoir is leaking or the TP valve of the water heater is releasing water. The TP valve basically stands for temperature and pressure relief valve. The TP valve should be placed on or close to the top of the water tank. On the basis of the location of the leaks, water can be found on the top, bottom or sides of the heating device. You can also find water on the floor or walls around it.

If water is present, then you have the turn off the breaker from the electric panel prior to approaching the water heater. Once you turn that off, you need to turn the water off via closing the valve above or near it. Note that you have to close it clockwise. If the area is dry, you also have to turn off the breaker so you can examine the cause of the issue.

Step 2: Take Out the Cover Plates

Take out the cover plates from the face of the water heater. You will basically find two of them. The energy cut-off or ECO which is the high limit switch is a safety device that helps cut off all the power connected to the upper and lower elements and their thermostats when overheating occurs. It should be located below the top cover and affixed against the reservoir above the upper thermostat directly.

In general, the energy cut-off trips when the water temperature in the reservoir gets in the range between 150 to 180 degree Fahrenheit. But that depends on the sensitivity of the heater. You cannot reset such safety device until the temperature of the water is cooler than that of the temperature in which the energy cut-off got tripped. This ECO switch basically differs the exact temperature drop that is required.

Step 3: Take Out the Insulation Pad

You will find a foam insulation pad right there inside the water heater. It helps conceal the button you which you need to access to reset the unit. You will have to take the pad out with your hands and keep it aside. There you will find a reset button which is red in color on the ECO. If you find any moisture surrounding the reset button or on the pad, chances are that the element gasket is leaking. So at first, you will have to fix the leaking. Then press the button to reset the water heater. You will hear a clicking sound if the heater has cooled down adequately and that the energy cut-off is working appropriately.

If the button does not click immediately, then keep your finger pressed against the button until you get the click sound.

What if you don’t hear the click?

If you do not get to hear the click after you press the reset button, then you will have to examine all the wires of the heater for loose wire nuts. If you think the wiring is fine, then perhaps you need to replace the controller.

Different heaters work in different ways. While some of them click immediately, some take five seconds to click. If you still don’t hear the sound, then reassemble the heater anyway as it will still restore the hot water.

If the Switch doesn’t Reset

Step 1: Thermostat Replacement

Replace the thermostat if the switch of energy cut off device fails to reset or if it trips frequently. Do the replacement task only if you have experienced, or else you will have to call an expert or a plumber to analyze and repair the issue.

Step 2: Interior Parts Inspection

Investigate the interior part of the heater for the sign of burn or overheating. If you are someone professional DIYer, then you can change the burnt out thermostats or heating elements. Besides, you can also change the anode rod if required. But all of these are dependent on your comfort zone and your experience. When the anode rod gets corroded, it affects the functionality of the water heater This kind of rods have been engineered to be a sacrificial part of the water heater so you can sacrifice it and get a new one when the existing one deteriorates.

Reassembling the Heater:

Step one: Put back the Insulation Pad

You will need to put the insulation pad back to the heater. Take the pad which you had taken out earlier.

Step 2: Screw Back

Then you will need to put the door on the control panel back in place and the screw it to fix it.

Step 3: Turn the Power On

Then have the cable plugged in for restoring the power. You can also flip the necessary switch for that. Wait for a few hours, your water should be heated by then to run properly.

Wrap Up!

So, this is how you reset the water heater. You have to be very patient while performing all the steps. However, If you have no idea regarding the way to switch off and reset the heater, then it’s better you call an expert to do that for you. It would be very risky to mess around with a water heater if it’s turned on.

most common water heater problems

Most Common Water Heater Problems 2019!

A water heater is one of the most satisfying things out inside your home especially when you are having a cold season. But you cannot really expect the device to work out properly throughout your entire life. It does not only offer convenience but comes with a lot of inconveniences as well. So, in this article, you will get to know what kinds of issues you can face for having a water heater in your home. We will not only talk about common water heater problems but also highlight the solutions that you can use to get rid of those problems. So here we go.

Most Common Water Heater Problems in 2019!

Failure to Heat

It is a common thing that sometime or later, your water heater can stop producing hot water. In this case, the broken or malfunctioning heating elements can be the main culprit. If not, then such an incident can also happen because of the faulty thermostat or its incorrect setting. You can also blame the water heater if it trips the circuit breaker since it can also interrupt the power and stop the device to produce hot water. For this, the first thing you much do is to make sure your pilot light is on. If it’s out, then simply turn it on. If you think the problem is bigger, then either you have to replace the device or fix it by yourself or by some pros.

Overheating Issue

If you sense scalding hot water coming out of your water tap, then do understand that something is up with the water heater. The most common cause of this when the elements or the thermostats of the water heater are set too high. For this issue, you can preset the water heater to 120-degree Fahrenheit.

Besides, the sediment build up can also cause the elements or the thermostats to get overheated. If that happens, then you will be required to drain or flush the water heater so you can remove the sediment.

Leaks Issue

One of the most annoying issues of the water heater. It happens when your tank-style water heater holds a lot of water at once. Besides, the problem can also occur for the faulty valve, faulty plumbing connection or corroded water heater tank.

The consequence of leakage can be messy and also can damage your home.

If you do not detect the water leaks for a long time, the damage can go worst. Replying on the placement of a water heater, a leak can damage your furniture, carpet and other belongings, it can mold and mildew growth, rot wall framing and floor joists.

If you want to avoid such an incident to occur, then you have to inspect your water heater at least twice a year. If you have placed your water heater on the upper floor of your home, then make sure you get a drip pan with a water alarm or drain inside it.

If you have placed a closed loop water system which comes with a backflow preventer or valve, then make sure that the water heater is equipped with an expansion reservoir.

Corrosion Exposure

Another major issue of the water heater. Not only it makes the water rusty color but also causes leakage due to corrosion.

When the water is fresh, it tends to carry a lot of oxygen and a host of minerals while it gets into the water heater. As a result, the water heater gets inclined to corrosion.

For this, the water heater comes with an anode rod. It rests in the reservoir of the water heater and it’s a few inches shorter than the internal height of the water heater. The anode rod uses aluminum or magnesium as its main material, so it happens to undergo the same corrosion as the steel one.

The anode works through the corrosive components in the water. These components tend to corrode the heater for which it gets rusted. This is the reason why experts recommend to check the anode rod twice a year.

However, if you use a water softening produce, then you have to inspect the rod annually.

You can also replace a rod if you think that the current one has no way to fix. The best thing to do is to frequently replace the anode rod so that your water heats last longer and never gets corroded.

Popping Sound

If you think the heater makes a popcorn or rumbling kind of noise, then it might have built up sediments.

Sediment built up is a common issue that occurs due to hard water which means water with a greater quantity of minerals. Over time, these minerals settle into the bottom of the reservoir of water heater that leads to creating a thick layer of sediments. This is what we call sediment build up.

Now, when these layers of sediment start to build, a small amount of water gets trapped beneath. Due to the this, the water gets overheated for the burners and forms steam bubbles eventually. The upward movement of bubbles pushes the sediment pile and this creates the popping sound.

So, in this case, you need nothing but have an expert flush your water heater so that you don’t damage your water heater.

Lukewarm Water

When you find out that the water heater is not producing enough hot water as it should produce, then there is a couple of reason that can cause this issue. Firstly, it can happen due to the faulty lower heating element or its thermostat. Secondly, it can happen due to crossed plumbing lines or improper installation. Thirdly it can cause due to faulty dip tube. In this case, you either have to fix the water heater element or the thermostat by a pro or you can to replace the element or thermostat so you can make the water heater last longer.

Wrap Up!

Now that you already know the problems, you can start taking preparation to find out the problems of the water heater. You can perform some tests with the tester or you can call an expert to help you fix the problem of the water heater. However, make sure that you inspect the device twice or thrice a month if you want it to last longer.

how to test water heater element

How to Test Water Heater Element 2019!

The cold season might trigger you to use water heater mostly. But just like all the other electric devices, a water heater can also stop working properly. The most mainstream situation can be the time when the heater produced less hot water or no hot water. And when that happens, the elements or their thermostats may be at fault. At this point, the first thing you should do is to check the functioning of the elements yourself. you can perform a test if you want to find out the culprit.

So, in the write, you will get to know how to test the water heater element properly. If you follow the steps just like the way mentioned here, you can complete the testing mission successfully.

How do Water Heater Elements Work?

Electric water heaters mostly come with two elements. And it’s possible that both or either of them could go off. Moreover, you will also find a thermostat for each of the elements.

If something goes wrong with the thermostats, then the elements will not be able to heat up. In this case, all you should do is: get a few testers and a couple of precautions. Then you’re all geared up!

Most of the time, it is seen that the upper element of heating and its thermostat control the lower one and its thermostat. If water heater no longer produces hot water, then either upper element or its thermostat could be the actual culprit. But if the device starts warming up water but it’s not as much hot as it should, then suspect the lower element or its thermostat.

But no worries! There are a few tests that you can do so you can understand the actual issue with the heater.

Things You’ll Need!

  • Noncontact voltage detector
  • Multi-meter
  • Voltage tester
  • Screwdriver
  • Safety goggles
  • Gloves

Methods of Testing

If you see your water heater that is tripping the circuit breaker continually, then perhaps it could mean that the element got grounded and might end up creating an electric short. At this point, you will need a multi-meter so you can find out how the elements went damaged.

Before that, you should turn off the breaker inside the main electric panel that provides power to the heating device. Majority of the water heaters use a circuit breaker that comes with 30-amp double-pole.

Try to find the panels that are fixed with the screws to each of the water heater’s sides. Relying on what the size your water heater is, the device will either have one or two panels. Take out the screws so you can release them from the panels.

Also, take out the insulation that was exposed whole taking out the panels. The type of insulation will depend on the age of the heating device, it could be either closed-cell extruded polystyrene foam or fiberglass.

Has it pulled the plastic safety cover from the face of the element? The cover basically snaps on and off the elements and the thermostats.

Then, use a non-contact voltage detector and hold it just next to the wires that are connected to the face of the element. And then hold it near to each wire that is connected to the thermostat. You will find the voltage detector emitting an audible alarm and flashing light if there is electricity present in the water heater.

Loosen the screws of two elements and take out the wires from the screws below. Keep a note of the wattage of an element that is written on the sides of the element face.

Rotate the dial on the multimeter to Rx1k which means ‘resistance times 1,000 ohms. Touch any of the screws of element face with one of the probes of the multimeter. Place the other probe on the other screw. If the element has 3,500 wattages, then it should register 1516 ohms, if it has 4,500 wattages, then it should register 12-13 ohms, and if it has 5,500 wattages, then it should register 10-11 ohms. Switch the element if it doesn’t register on the multimeter.

Leave any of the probes touching one of the screws on the face of the element. Then leave the other probe touching a metal part of the heating device. If the needle of the multi-meter happens to move, then the heater element is grounded. It means you must replace the element.

It is also important to ensure that you test both the screws on the element face.

Touch each of the screws with one of the probes of a multimeter. Place the other probe against the base of the metal that is connected to the element where it enters the heating device. If the needle on the face of the multi-meter moves, then it means that the element is damaged and you must replace it.

Have it attached the wires back to the face of the element. Clip the plastic cover on the element and the thermostat. After that re-install the insulation and fix the panels to the sides of the water reservoir. Then, turn on the breaker to the heating device.

Safety Tips

Make sure before you step into the testing water heater, you wear safety gears such as goggles and gloves. These gears will keep you protected from any accident or risk that can occur during the inspection. Also, check if you have unplugged the main power of the heater and turned it off. You should also drain the water from the tank as well before conducting a test of the water heater element.

Wrap Up!

Testing water heater element can be a little time consuming, but it needs nothing but some testers, gears and your determination. If you get dependent on someone professional, then it is expected that they will end up charging you up with a lot of fees. But, if you can get the job done on your own, then it will not only be convenient to fix a damaged water element but also save you up a lot of your money. Hopefully, now you will be able to test the water heater element in a proper way without the need of any professional.

what size water heater do I need

What Size Water Heater Do I Need 2019!

Planning to get a new water heater for your home? Confused which one to get or what size you need? These are some questions that are likely to mess up with your mind. But how about we help you with the guides of getting the ideal size of your water heater?

Size is one of the most essential factors when it comes to getting a perfect water heater. There are many sub-factors that can help you get the ideal one. If you want to know everything, then you will need to go through the whole write that will answer to this most common question- what size water heater do I need?

Key Factors

If you want to look for an ideal water heater, just like we have mentioned, there are some key factors that you must keep in mind

Area Size

You will also have to ensure that you get a heater in such size that can fit the designated space in your house.


Will you and your partner be using the heater or you have a big family for using the device. The size and occupancy of your family are also two of the most essential factors that you must keep in mind before making a purchase.

Source of Fuel

Determine the type of source for fuel. It can be electricity, natural gas or liquid propane. Besides, it can also be the one coming connected to your boiler. Once you decide this, it will help narrow your preferences down so you can have the perfect water heater for yourself.

However, if you have a big family in your house, then you might require a high capacity water heater so it can provide accommodations for multiple people to shower up, wash dishes or do laundry at the same time. It’s because a condo will let you use the heated water for one task at a time.

Sizing of Storage Tank Water Heater

If you want to get the ideal size of a storage tank water heater for your house, then you will need to note down the member size at first. This type of water heater sized on the basis of British Thermal Unit (BTU) input and gallon capacity. The more you will depend on hot water regularly, the more BTU inputs and gallons you will need.

This is a rough guide you can follow to get an ideal storage water heater:

Family Size Capacity in gallons
1 to 2 30-gallon
2 to 3 40-gallon
3 to 5 50-gallon (electric), 40-gallon (liquid propane or natural gas)
Above 5 80-gallon (electric), 50-gallon (liquid propane or natural gas)

Sizing of Tank-less Water Heater

A tankless water heater is rated by the highest temperature rise at a certain flow rate(gallon capacity per minute). So, to get an ideal size of a tank-less water heater, you are required to determine the temperature rise and flow rate you will need for the application. The application will be varied in the size of the house. It could be within a small area such as a bathroom or could be the whole house.

 Flow Rate: 

Firstly, you will need to list the number of hot water devices that you want to use at a time. Afterward, add up the flow rate of the devices. The number that will come is the desired flow rate you will want for such type of water heaters. Let’s say, it is likely to run a hot water tap simultaneously with a 0.57-gallon (or 2.16 liters) flow rate per minute and a showerhead with a 2.5-gallon flow rate (or 9.5 liters) per minute.

The rate of flow through the tankless water heater is required to be at least 3.25-gallon (or 12.3 liters) per minute.

 Temperature Rise: 

Then you will need to settle on the temperature rise. For this, you will need to subtract the temperature of water incoming from the preferred output temperature. Suppose, the temperature of the incoming water is 50-degree Fahrenheit. For most uses, you will want the water to have a temperature of 120-degree Fahrenheit. Here, you might demand a tank-less water heater which can generate a temperature rise of about 70-degree Fahrenheit

Majority of the tank-less water heaters are measured for a different range of inlet temperatures. In general, a 70-degree Fahrenheit temperature rise of water occurs at a flow rate of 2-gallon per minute by electric tank-less heaters and 5-gallon per minute through gas-fired ones.

Cooler inlet temperatures or faster flow rates can decrease the temperature of water sometimes at the most distant tap. There are some kinds of tank-less heaters that can be controlled thermostatically: such can differ the out temperature in accordance with the inlet temperatures and flow rates.

Sizing of Solar Water Heater!

Solar water heater sizing usually involves the determination of the total collector area and the storage volume. Solar system contractor uses computer programs and worksheet so it can help in determining the system necessities and sizing of the collector.

Collector Area
Contractor basically follows a parameter of about 20-square feet of collector area for the two people mostly. For each extra person, 12 to 14-square feet is added if you dwell in the northern United States or 8-square feet is added only if you dwell somewhere in the Sun Belt area of U.S.
Storage Volume
The water tank that comes with around 50 to 60-gallon capacity should be enough for two to three members. If the family is medium sized, then water tank of around 80-gallon capacity will be sufficient for four to five member. If the family size is bigger than this, then a large tank will work well for around six people at the max.

The size of the solar storage reservoir rises with the collector size. In general, it will be 1.5-gallon per square foot of the area of a collector.

It will help avoid the system from getting overheated when the demand of using heated water is lower.

It’s like you will definitely no prefer using hot water in warm sunny season right?



how to maintain water heater

How to Maintain Water Heater 2019!

A water heater is likely to last around 7 to 12 years depending on the proper maintenance. So, if you want the heater to work properly then maintenance is definitely required. Be it regularly, week, monthly or annually, it is essential that you examine every part of the heater.

However, we would never advise you to maintain the water heater if you don’t have any experience working with electricity or plumbing.  So, it’s better to go for it only if you think yourself someone experienced.

Coming back to the main point, the water heater requires some love and care since it will boost up the performance of the unit.

And if don’t know how to maintain a water heater, then this guide will help you out.

Services the Water Heater

If you plan to go through regular servicing, you won’t be needing any expert to do the task for you. With the help of a bucket and a screwdriver, you can conduct the servicing task of the water heater all by yourself. Prior to going for it, make sure you turn the power off for safety.

Turn the circuit breaker for the water heater in the breaker box.
Turn the pilot knob (that is situated on the thermostat or valve of the water heater) to the off point.

TPR Valve Test

Turn the power and the water supply valve off. Have a bucket placed below the pipe that is linked to the TPR (temperature pressure release) valve on the side or top of the water reservoir. The TPR valve opens only when the pressure of the tank is higher. Lift the tab of the valve to drain the tank. If the water keeps on flowing, then drain it halfway. With a pipe wrench, unscrew the old valve and set up the new one. It’s because frequent replacement of TPR valve will help the water heater last longer.

Anode Rod Analysis

Place a hose to the drain cock of the reservoir and let a few amounts of water gallon drain. Now, put a 1 1/16 inches socket on the top of the anode rod’s hex head onto the heater.

Then unscrew the rod. If it is coated with calcium or is less than 0.5 inches thick, then you have to get a new one and wrap the threads with a seal tape.

Then, place the new rod back to the reservoir and after that tighten it firmly.

Sediment Subtraction

Drain the water into the bucket from the tank and start gearing up to wash out all the sediments that have built up on the bottom of the tank. Removing the sediment will prevent rust and also enhance the energy efficiency of the heater.

The best will be only if you do a complete flush of the unit, although it will require the shutting down of the water heater.

However, you can also opt for a mini-flush since that will work well enough for washing out the sediments. It will take a fraction of your time and you can do it while running the water heater.

Have a bucket placed below the drain valve that is there close to the bottom of the tank.

Dial the valve counterclockwise so you can drain about 2-gallon of water into the bucket. While some drain valves comprise of a short stem with a slot to use a screwdriver, some of them come with a handle. However, after you finish doing the mini flush, dial the valve clockwise to close it back.

You have to be very careful while doing the task since the water will be scalding hot and it can burn you up.

Temperature Adjustment Tasks

Unscrew the cover after you notice the temperature dial on the water tank’s side. Water heaters are basically preset to the temperature of 130 to 140 degree Fahrenheit. If not, then it is better to adjust the temperature by dialing to 120-degree Fahrenheit using a screwdriver. You can expect to save around 5% of the energy bill for lowering every 10-degree temperature. If you are planning to be away from home for quite often, switch off the water heater and tune the thermostat down to its lowest setting.

However, you might also require to take out a small metal panel that covers the thermostat, if you want to lower the temperature.

For this, turn off the breaker at the breaker box and switch off the power of the heater.

Then, you have to take the access panel of the thermostat and set the temperature to your preferred setting.

After that, have the thermostat cover replaced and switch on the power again at the breaker box.

Mission – Pipe insulation

Make a purchase of a couple of self-sticking foam pipe insulation that comes in 3/8 inches thick and matches the diameter of the pipe. Slide the foam pad on the pipes as far as your hands can reach. Squeeze the insulation closed after peeling the tape. If the pipe is 6-inch long or lesser from the flue, cover it using the fiberglass pipe wrap. Make sure the wrap is 1-inch thick.

If you insulate the cold water pipe, it will help prevent the condensation during summertime.

Mission – Heater insulation

Cut the insulation blanket so it can fit the Temperature pressure release valve, the pipes and the temperature control that has been stuck out of the tank. Seal the cuts using a tape after wrapping the side of the tank. Don’t cover the top of a gas or propane liquid heaters. But as for the electric ones, cap the heater using insulation that’ll come in an oversized circle. After that, wrap the edges with the tape securely to the tank’s side.


Maintaining the water heater is definitely not one’s cup of tea. But if you want to enjoy the privilege of warm water, then you have to show enough care.

As we have underlined every part and area of the water heater that you can perform maintenance on, it will be easier for you to do all the task.

But before that, don’t forget to judge your level of expertise!
