Why Tankless vs. a Traditional Tank?

Produce more hot water using less energy than the most efficient storage tank style heater. Tankless is the environmentally responsible water heating solution. It saves energy, saves space and saves you money.

Endless Hot Water

Rinnai tankless water heaters heat the water you need, when you need it. Turning any water source into hot water on demand. You are not limited to the amount a storage tank heater can hold. Whether you are washing the dishes, washing your clothes, or drawing a hot bath, Rinnais tankless water heater technology will supply endless hot water to your lifestyle demands-even if you do them all at once!

Lower Energy Bills

Enjoy up to 40% energy savings with a Rinnai tankless water heater. Our units are designed to be highly efficient and only heat water when it is needed, a revolutionary advantage over inefficient tank-style heaters.

Clean, Fresh Water

Traditional tank-style water heaters can build up rust and scale inside their tank, where the hot water you use for bathing and drinking is stored. With Rinnai tankless water heaters you will always experience fresh, clean water that is heated on demand, as it passes through the unit.

Sustainable and "Green"

Rinnai has earned ENERGY STAR approval by meeting the strict energy efficiency guidelines set by the U.S. Environmental Protection Agency and the Department of Energy, by using less energy and preventing greenhouse gas emissions.
