Tankless Water Heater in Houston, TX

What is a Tankless Water Heater?

An Arrow Plumbing installed tankless water heater only heats water when you need it. So you get on demand hot water, while also saving money on energy costs by not heating and reheating the same tank of water.

  • When opening a hot water tap, or starting the dishwasher, the tankless water heater recognizes the need for hot water and starts the heating process.
  • The temperature of the incoming water is used to calculate how much heat the burners must produce to deliver water at the desired temperature.
  • When the demand for hot water ceases the unit shuts down and uses no energy, waiting until more hot water is needed.
  • The end result — hot water that is not limited to what’s available in your tank. You always have clean, hot water when you want it for as long as you need it!
