What Are The Different Types Of Water Heaters?

Have you decided to acquire a water heater and now, you are looking for a perfect option? While doing research, you will understand how vast the market is and how complicated it is to choose one option out of many.

Conventional (Tank) Water Heaters

A tank water heater is the most common and traditional type of water heaters available currently in the market. It arrives with a tank that stocks water to be heated. The capacity of the tank determines how much hot water you can hold at once.

If the tank size is small and you have a big family, you may run out of the water and have to wait for an extended period of time for the next container to be heated.

Just because it works nonstop, so you will have to clean it frequently to increase its lifespan. It is critical to clean it twice a year to eliminate mineral deposits and reduce corrosion.

It is not mandatory to clean it and it works properly even without being cleaned, but won’t last long. The average lifecycle of a standard tank heater is up to ten to twelve years only.

Condensing Water Heater

If your home uses natural gas as its primary energy factor and has gas lines around, then condensing heater is an ideal fit for you. It comes with a tank just like standard heaters and utilizes the unused gas vapors at your residence to produce heated water.

The gas vapors funnel through a coil situated at the bottom of the container to heat the water. It consumes a very little amount of energy (apart from the gas vapors that are burned somewhere else like by your oven or stove) to heat the water.

To take advantage of this unit to the fullest, it requires a backup plan such as electricity or gas, so that you can continue to get warm water on cloudy days.

Heat Pump Water Heater

High Installation Cost
