Common Questions

  • What Is a Tankless Water Heater?

    A tankless water heater, also referred to as an instantaneous water heater, provides hot water only as it is needed. Unlike storage water heaters, tankless heaters do not overproduce water, which ends up sitting unused, thus leading to energy loss.

  • How Do They Work?

    Tankless water heaters heat water without the use of a storage tank. When a hot water tap is turned on, cold water travels into the unit and either a gas burner or electric element heats the water instantaneously.

  • What Are the Benefits of Tankless Water Heaters?

    Tankless water heaters are the efficient, energy-saving alternative to a conventional water heater. They take up less space than conventional heaters do, and also lead to significant savings on your energy bills. Additionally, tankless heaters have a life expectancy of 20+ years, while conventional heaters only last about 10-15 years.
