When Should You Replace Your Water Heater?
To know when to replace your water heater, you should always look at the expiring date of your model. Most water heaters are supposed to last for 8-10 years, but quite a few might not make the cut for different reasons. Some of these reasons include rust, leakage, noises, and unheated water.
If you find any rust in your tank or the water it is heating, know that it is time for a replacement. The same goes for when it’s making unusual noises or leaking.
And if it fails to do the main purpose it was purchased for – that is – to heat water, then you should also look for another alternative. You should, of course, try maintenance and talking to a professional first, though.
How Does Water Heater Work?
There are different types of water heaters, and each one works differently. We are going to see how three main types– tank, hybrid, and tankless water heaters work –
Tank Water Heaters
These types of heaters are the most common in households and feature a large storage tank. It operates either by gas or electricity. When cold water enters the tank, it is heated up by either a gas flame or electrical components, and then distributed to the output points.
While a gas-operated tank heater is more expensive than the electric one, it costs less energy.
Hybrid Water Heaters
A hybrid water heater consumes the least amount of energy among these three types. Through the help of a condenser and evaporator, this product heats up the water by using the heat from the room it is in. This saves almost 60% of energy. It is operated by an electric pump.
Tankless Water Heaters
This kind of water heater is also known as an on-demand heater because it does not store any water previously for heating. When any hot water tap is opened, water is heated in the tankless unit by a burner or electric components at the preset temperature, and then delivered straight to the faucet point instead of being stored.
These models save 34% energy than regular ones.
Water heaters have become an essential part of most people’s lives now. Whether you need to replace your existing one or purchase a new product to see the benefits that come along with it, we hope this best natural gas water heater reviews will help you.
