FAQ:

Q: Should you consider tankless water heaters?

Q: Do tankless water heaters really save energy?

A: A tankless water heater detects when you turn on the hot water tap and heats the water as it passes through the unit. When you turn off the tap, the tankless water heater also turns off. This helps save energy and money. Being tankless also means that these units are much smaller.

Q: How energy efficient is a tankless water heater?

A: Efficiency is a measure of heat transfer from a power source for hot water. Tankless units are usually operating at more than 80% energy efficiency. Tankless water heaters offer more energy saving standard water heaters, because the water does not need to continuously heat and only heats water on demand.
