Unlike traditional storage tank water heaters, Rinnai tankless water heaters do not store a reservoir of hot water. As a result, standby losses are reduced, which makes them an energy-efficient alternative to traditional water heating. When water flow is detected, they begin heating water, making them highly efficient and cost effective. When the demand for water ceases, they enter standby mode and use essentially no energy.
There will always be hot water. Endless hot water - for bathing, cooking, dishes, laundry, and all the other countless ways hot water enriches our lives.
Tankless water heaters consume a fraction of the space consumed by a tank heater. They can be mounted inside or outside.
