Tankless water heaters produce more hot water using less energy than the most efficient storage tank heater. If you're looking for an environmentally responsible water heating solution that saves energy, space and money, a tankless water heater is for you.
A tankless or on-demand water heater only heats water when you need it. So you get an endless source of hot water, while also saving money on energy costs by not heating and reheating the same tank of water.
Endless Hot Water
You can turn any water source into hot water on demand. You aren't limited to the amount a storage tank heater can hold. Whether you're washing the dishes, washing your clothes or drawing a hot bath, tankless water heater technology will supply endless hot water to your lifestyle demands, even if you do them all at once.
Lower Energy Bills
Take advantage of up to 40% energy savings with a tankless water heater. Units are designed to be highly efficient and only heat water when it's needed.
Tankless water heaters typically last up to 20 years, twice as long as a tank-style unit.
Traditional water heaters can take up to 16 square feet of valuable floor space. Tankless water heaters are about the size of a carry-on suitcase and can be installed on virtually any wall inside or outside of your home.
Clean, Fresh Water
Traditional water heaters can build up rust and scale inside the tank, where the hot water you use for bathing and drinking is stored. With tankless water heaters, you'll always experience fresh, clean water that's heated on demand as it passes through the unit.
