A tankless heater runs on propane or natural gas to perform the task of water heat up. It only requires a place of 2 cubic feet in your home or apartment.

How does a tankless water heater work

Tankless heaters don’t have to put a lot of effort into providing you with hot water. That’s why they utilize less energy than a tankless heater. So what happens is, when you open a tap, the heater receives a signal that hot water is being used. So the water passes through either an electric heat exchanger or a gas burner. You can gain 2-5 gallons of water in just a minute. The heater stops working when you turn the tap off. That means that you can control the tankless water heater by fixture or any other water outlet.

Tank-style Vs. Tankless

We will decide the winner in the final round of the battle between the two types of water heaters. But the winner is not one. Because both heaters have their advantage over the other in different circumstances. For example, tankless heaters lift the winner’s trophy if you live alone or with a small family of 2-3 members. 

You won’t have to use the heater to wash the clothes and dishes, and the heater will efficiently manage the load of hot water demand. Alternatively, the tank-style water heater is an excellent pick if you have a large family whose clothes need to be washed once or twice a week.
