The tankless type of water heater heats up the water as you need it. There is no tank where water is stored and kept hot for future use. This keeps your costs lower, because you don’t need to expend the energy to keep the stored water warm.

Advantages and Disadvantages

As mentioned, one advantage of this type of water heater is the lower cost of operation. There is no need to heat water that is just sitting there and not being used. Another advantage is that if multiple people want to take a shower in quick succession, there is no waiting until the hot water tank is refilled and heated up. The hot water is always available when you need it.

The main disadvantage of this type of heater is the initial cost of purchasing the unit. This is offset by the lower cost of operating the unit. Also, the tankless type of water heaters last longer than other water heaters before they must be replaced.

How Does a It Work?

These tankless water heaters heat the water by means of a heat exchanger. When water comes out of the tap, it flows to the heat exchanger, where the water is heated up by use of either gas or electricity. Then, the water flows to where it is needed, such as your shower or sink. Because the water is heated as needed, the amount of hot water produced is limited to a certain flow rate. However, you can install more than one of these heaters. You could install one for the dishwasher, one for the washing machine, and so on.
