While a standard tank may heat and reheat water even when your not at home, tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only as it is needed. Tankless water heaters don’t produce the standby energy losses associated with storage water heaters, which means lower energy bills and more money in your pocket.
Tankless water heaters heat water as it goes through the pipes, giving you an endless supply of hot water for your family or business. They also have a longer lifespan, about twice as long as a regular tank. Plus, tankless water heaters have lower maintenance costs allowing you to easily replace parts rather than the entire system.
Tankless water heaters are about 90% smaller than standard hot water tanks and can be installed in compact or non-traditional spaces.
