What are Self-Cleaning Water Heaters?

A self-cleaning water heater is equipment designed to reduce the sediment build-up inside its tank. Unlike normal water heaters, where water sediment tends to build up on their bottom with the passage of time, self-cleaning water heaters use internal water circulation to flush out the unwanted materials.

Such kind of functionality comes handy in two ways.

First of all, a self-cleaning water heater helps prevent the sediments from taking up valuable space in the tank. Secondly, it protects you from the trouble of having to flush out the tank after every few weeks.

In this article, we are going to take a comprehensive look at the self-cleaning water heaters. We’ll also look at how self-cleaning water heaters work and what is the probable lifespan of these units. Finally, we’ll take a look at whether these types of heaters are worth your valuable investment in the long run.

How Do Self-cleaning Water Heaters Work?

Powered by gas or electricity, a self-cleaning water heater is designed to perform the same function as that of its standard counterpart. They might look exactly the same as that of normal water heaters, but the main difference comes in the form of a dip tube that is equipped with a special fitting.

Sediments enter into the tank with the normal cold water through the intake pipe. Once inside, they fall to the bottom of the tank that effectively reduces the heater’s efficiency. However, a dip tube keeps these unwanted materials swirling at the bottom, not allowing them to settle down on the surface.

Such kind of arrangement means that the next time you open the hot water tap, these materials will get sucked out on their own. As a result, you don’t have to worry about unwanted materials lying around in your water heater.

Some of the vital components of this equipment include an anode rod, an effective self-cleaning system, heat trap nipples and a drain valve. These components can vary, depending on the heater’s manufacturer, but their main function is all the same: to ensure a smooth functionality of this unit.

Pros and Cons of Self-cleaning Water Heaters

Here are some of the advantages and disadvantages one need to consider before investing in a self-cleaning heating water.

Pros of Self-Cleaning Water Heaters

Energy Efficient

One reason why normal water heaters tend to consume more energy with the passage of time is due to the regular build-up of sediments. These materials can also accumulate on the heating element, meaning it has to use more energy for doing the same job.

However, there’s no such thing with self-cleaning water heaters. They remove most of these sediments on their own without allowing them to build up on their bottom. It thus saves your heating element from doing the extra work which, in turn, allows the heater to work optimally at all times.

This will lead to greater savings in your energy bill every month. It means that even though this equipment is expensive as compared to a standard water heater, this cost can be compensated by the fact that they’re energy efficient in the long run.

Ease of Maintenance

A normal water heater requires regular cleaning after every six months. It includes flushing your tank and removing the sediment build up with your own hands. All of this requires a regular cleaning schedule or otherwise, you might end up with layers of sediments in your water tank.

There is, on the other hand, no such worry with a self-cleaning water heater. This equipment uses internal water circulation to remove the sediment build-up which keeps it neat and clean without external help.

It means when you don’t have to worry about flushing out the tank after every few months, you can spend this time in other useful tasks.

Cons
