  • A tankless water heater heats water on demand. Cold water enters the unit, a flame ignites, and it passes through heat exchangers (pre-heating and primary). Once you turn off the tap, the flame shuts off. This way you get hot water only as needed, with minimal wasted energy.

  • They can operate on natural gas or propane. In some cases, for all-electric homes, there may be electric tankless options, check with a certified professional.

    • Lasts up to twice as long as tank models.

    • Saves energy by heating only when needed.

    • Higher efficiency (higher UEF), lower operating costs in many cases.

  • They are quite compact, approximately the size of a carry-on suitcase, so they can fit in small spaces like closets, cabinets or mudrooms

  • The upfront cost may be higher than a conventional tank heater, but over time you save through lower energy bills, longer lifespan, fewer replacement events, and better durability.

Tankless Water Heater F.A.Q.

  • Yes. Some models are Wi-Fi capable, allowing you to monitor and control things like scheduling, recirculation, etc., via smartphone or voice-control devices.

  • A recirculation feature helps eliminate the wait time for hot water. It keeps hot water ready even if your home doesn't have a dedicated return line.

  • They are rated by something called UEF (Uniform Energy Factor). Tankless & condensing models typically have much higher UEFs than tank models. Some are ENERGY STAR certified, giving extra energy savings.
