What are Tankless Water Heaters? Tankless water heaters are small heating units that are typically mounted to the wall. These heat water on demand, using far less electricity than traditional water heaters. There are a number of these devices on the market with different flow rates and water pressure. Some can run on propane or natural gas.


  • Operating Cost: Unlike traditional models, these heaters don’t keep many gallons of water piping hot at all times. If you only need hot water at certain points in the day, a tankless heater can slash household energy use by 50%.
  • Space Saving: Most tankless water heaters are about the size of a suitcase. They easily fit on the wall or in a bathroom cabinet.
  • Lifespan: Tankless water heaters typically last for 20 years or more. Traditional heaters last an average of 10 to 12 years.


  • Initial cost: Tankless water heaters come with a higher price tag than traditional models. The unit itself may be two or three times the cost of a tank, and you may need a professional plumber to retrofit your pipes for installation.
  • Limited Output: Tankless heaters typically only provide for one faucet at a time. Models that serve multiple faucets may struggle to keep water hot across all taps.​

Are They Right For You?

Tankless water heaters are ideal for homes with low water usage requirements or for specific appliances like a hot tub. They may not work for heavy usage families, and can be difficult to install in older houses.
