To clean a tankless water heater, turn off power and water supply, remove and clean the filter, flush the unit with vinegar, and then with water. With these basic steps, cleaning your tankless water heater will ensure it functions efficiently and lasts longer.
Your tankless water heater operates without storing water; instead, it heats water on demand when you open a tap or faucet, or when you turn on your shower. This means that over time, limescale and mineral deposits can accumulate inside the unit, which can lead to a reduced flow of hot water, damage to the heating elements, or even complete breakdown of the unit.
As a result, it is important to clean your tankless water heater regularly to keep it functioning correctly. Here we will explain how to clean your tankless water heater manually.
Why Clean Your Tankless Water Heater?
Tankless water heaters are an amazing innovation that provide hot water instantly while saving energy. They are much more efficient than traditional water heaters, but they still require maintenance to maintain their efficiency. Cleaning your tankless water heater is an essential task that is often overlooked but really important to ensure your heater performs well for years to come.
In this post, we will discuss why cleaning your tankless water heater is crucial and the benefits of doing it regularly.
Benefits Of A Clean Tankless Water Heater:
A well-maintained tankless water heater comes with many advantages that you wouldn’t want to miss out on. Here are some benefits of cleaning your tankless water heater:
- Improved efficiency: Over time, mineral deposits and debris build-up in your tankless water heater clog the system, reducing its efficiency. By cleaning your heater regularly, you can remove these sediments and boost the efficiency of your tankless water heater to operate optimally.
- Saves money: A tankless water heater that is functioning correctly will save you money. If it is clogged, it will not work correctly and use more energy to heat water. Regular cleaning ensures that the heater is functioning at its highest efficiency, saving you money on energy bills and prolonging its life.
- Increases lifespan: Cleaning your heater is an effective way of extending its life span. Regular maintenance helps prevent breakdowns, leaks or corrosion. With proper maintenance, a tankless water heater can last up to 20 years.
- Prevents damage: Sediments and limescale build-up in your tankless water heater can cause significant damage, such as leaks and clogs. Regular cleaning removes the limescale and sediment build-up, ensuring that your heater operates correctly, extends its lifespan and saves you money in the long run.
How Buildup Affects The Performance And Lifespan Of A Tankless Water Heater:
Minerals and other debris build-up in tanks over time, and tankless heaters are no different. The build-up is called limescale, which gradually clogs pipes, causing blockages, and reducing water flow in your heater. Here are some ways that limescale affects the performance and lifespan of a tankless water heater:
- Reduces efficiency: The build-up of limescale can make a tankless water heater less efficient by decreasing its heating capacity. As a result, you will have to wait longer for hot water, and your heater will use more energy to heat the water.
- Shortens lifespan: Limescale build-up can cause corrosion in your tankless water heater’s heat exchanger. Corrosion reduces the lifespan of the heater, causing more frequent repairs and lower efficiency.
- Causes damage: Limescale build-up can significantly damage your tankless water heater. It can cause leaks and clogs, affecting the heater’s performance and leading to expensive repairs.
Comparing The Efficiency Of A Clean Tankless Water Heater To A Dirty One:
A clean tankless water heater has significant advantages over a dirty one:
- A clean tankless water heater operates efficiently, heats water quickly, and saves energy. A dirty one, on the other hand, is less efficient, requires more energy to heat water, and takes longer to provide hot water.
- A clean tankless water heater is less likely to break down, require repairs, and need maintenance, all of which are time-consuming and expensive. A dirty tankless heater, on the other hand, will have more frequent breakdowns, repairs, and maintenance.
- A clean tankless water heater has a longer lifespan compared to one that is dirty. A dirty tankless water heater corrodes faster and has shortened lifespan, resulting in more frequent replacements.
By now, you know why cleaning your tankless water heater is crucial. Cleaning it regularly not only ensures that it continues performing optimally, but it also saves you maintenance costs, reduces breakdowns and extends its lifespan.
