Energy savings with less waste: ENERGY STAR® certified tankless water heaters are much more efficient than a storage tank water heater and water is only heated as needed, so less energy is wasted.

  • Endless supply of hot water: When your home hot water needs are high, enjoy the convenience of a continuous supply of hot water.
  • Longer equipment life: Equipment can last up to 20 years – a much longer lifespan than standard hot water storage tanks.
  • Optimize your space: Compact design and wall mounted installation helps to save space in your utility room. Some models can even be installed under a sink.
