Tankless Water Heaters vs. Traditional Storage Water Heaters

Tankless water heaters, also called instantaneous or on-demand water heaters, provide hot water only when you need it. Therefore, they avoid the standby heat losses associated with storage water heaters - resulting in an energy savings for you. Traditional storage water heaters keep water heated continuously and hold the heated water in a storage tank.

How They Work

When a hot water tap is turned on, cold water travels through a pipe into the unit. In an electric Tankless Water Heater an electric element heats the water. In a gas-fired Tankless Water Heater a gas burner heats the water. As a result, Tankless Water Heaters deliver a constant supply of hot water. You don't need to wait for a storage tank to fill up with enough hot water.

Pros And Cons Of Tankless Water Heaters

Tankless water heaters cannot supply enough hot water for simultaneous, multiple uses in large households. For example, taking a shower and running the dishwasher at the same time can stretch a Tankless Water Heater to its limit. To overcome this problem, you can install a "whole house" type Tankless Water Heater or install two or more Tankless Water Heaters, connected in parallel for simultaneous demands of hot water. You can also install separate Tankless Water Heaters for appliances - such as a clothes washer or dishwater - that use a lot of hot water in your home.
