What Is a Tankless Water Heater?
A tankless water heater heats up water on demand instead of storing heated water in a storage tank. Due to its short heating time, tankless water heaters are perfect for cooking areas, additional bathrooms, or any place where water needs to be used at any time. Also, because of its on-demand heating instead of a holding tank, our tankless water heaters are 90% smaller than a traditional water heater.
Tankless Benefits
Endless, on-demand hot water
Provide endless hot water on demand with no preheating or sudden temperature fluctuations.
Better Value Than a Tank
Water is only heated when you need it, not stored in a hot water tank. The self-modulating temperature technology only uses energy to heat up water while you are using it, which saves up to 50% on water heating costs compared to a typical tank water heater.
Save Valuable Space
A water heater in the basement or utility closet takes up a ton of space. This wall-mounted water heater uses 90% less space than a traditional hot water heater with a tank.
