What is a tankless water heater?

A tankless water heater provides hot water on demand, heating water only when needed rather than continuously using fuel to heat water in a storage tank. When a hot water tap is turned on, cold water travels through the heat exchanger in the tankless unit and is warmed instantly.

  • Whole-house tankless systems deliver hot water to all the fixtures and appliances throughout the home.
  • Point-of-use tankless models are smaller units designed to provide hot water to a single fixture or appliance.

Where to install a tankless water heater?

Plumbers can install tankless water heaters on inside or outside walls, including utility rooms, attics, garages, or basements.

Tankless units installed outside can freeze and needs protection from the weather, direct sunlight, rain, and bugs.
