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.

How do I know if I need a new water heater?

Signs a water heater is going out:

  • Rusty, discolored, or metallic-tasting water
  • Loud clanging, knocking, gurgling, or whining noises
  • Hot water that runs out quickly
  • Low water pressure
  • Foul odor coming from hot 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

Will a tankless water heater work without electricity?

A tankless water heater does not work without electricity. Natural gas and propane tankless water heaters need electricity to operate the internal PC board, ignition, and thermostat.

  • More energy-efficient and saves $150 to $300 in annual operating costs
  • Warranty lasts up to 5 years longer
  • Provides a higher gallons-per-minute (GPM)
  • Most gas units are eligible for a $300 federal tax credit

Electric tankless water heaters are:

  • Cheaper to install

Stanley installed a water heater that was too big to go into the utilities closet. With a little extra work, it fits. He made a return trip no charge. Have his business card taped to my water heater just in case. What more do you need to know? Give him a call he's a good guy!
