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 water heaters can also be installed in place of an old tank water heater if the area provides enough combustion air. Tankless units installed outside can freeze and needs protection from the weather, direct sunlight, rain, and bugs.

  • Rusty, discolored, or metallic-tasting water

  • Low or irregular water temperature, or no hot water at all
  • Leaks at the base of the tank or around the pipes at the top of the tank

  • Warranty lasts up to 5 years longer
