Tips For Faster Water Heater Heat-Up Time
When it comes to taking a relaxing hot shower, the last thing you want is to wait forever for your water heater to heat up. Nowadays, most water heaters take approximately 30 minutes to reach an ideal temperature, which is enough time to perform other activities such as getting dressed, brushing your teeth, or even taking your pet for a walk.
But wouldn’t it be great if you didn’t have to wait that long? Here are some tips for faster water heater heat-up time that can help you save both time and money.
Adjusting Incoming Water Temperature
One of the most effective ways to reduce your water heater heat-up time is by adjusting your incoming water temperature. Since most water heaters are preset at 140°f, a degree that is too high for most household activities, you can adjust it down to 120°f.
This reduction in temperature means that the water heater won’t have to heat up as much water, hence a shorter waiting time. Lowering the incoming water temperature to 120°f is also a great way to prevent any accidental scalding.
Reducing Standby Heat Loss
Whether you know it or not, your water heater keeps heat in standby mode even when you’re not using it. This standby heat loss can be a significant drain on your energy bills and increase your water heater heat-up time.
Luckily, there are a few ways to reduce standby heat loss and thus promote faster heat-up times. One of the most effective ways is by wrapping your water heater tank with insulation. Insulation helps to maintain heat better, reducing the amount of standby heat lost.
Upgrading Insulation
Another way to make sure that you’re not losing heat is by upgrading your insulation. Poorly insulated water heater tanks can lose heat much faster, meaning it takes longer for the water heater to reach its optimal temperature. A good rule of thumb is to check your insulation every three years to ensure that it hasn’t become compromised.
If necessary, you can add extra insulation to help keep the heat in and reduce heat loss.
Proper Sizing Of Water Heater
One of the most overlooked factors that affect water heater heat-up time is the water heater’s size. It’s essential to ensure that you have a water heater that is the right size for your home’s hot water needs. A water heater that is too small won’t heat enough water, so you’ll have to wait for the water to heat back up while a water heater that is too large will waste energy and thus money, having to heat more water than necessary.
Ensure that you purchase a water heater size that suits your home’s needs.
These tips can help you save both time and money while ensuring that you always have hot water readily available. With a water heater that heats up faster, you can easily grab a hot shower or run a hot bath without necessarily having to wait for half an hour.
Remember, less energy used on water heating equals more money in your pocket and less impact on the environment.
