    How Does a Tankless Water Heater Work?

    The Process

    1. A hot water tap is turned on.
    2. Water enters the heater.
    3. The water flow sensor detects the water flow.
    4. The computer automatically ignites the burner.
    5. Water circulates through the heat exchanger.
    6. The heat exchanger heats the water to the designated temperature.
    7. When the tap is turned off, the unit shuts down.

    Water Heater Repair & Maintenance

    We repair all makes and models. And with each repair comes a complete safety inspection for your added peace of mind. At the same time, we offer you these additional hot water services and solutions:

    • A pressure regulator to help maintain a consistent and desirable level of water pressure.
    • Hot water “on-demand”… from the moment you turn on the faucet or tap.
    • A water alarm that activates when your system springs a leak.
    • Recirculation pumps, a relatively new and highly innovative pump system that delivers hot water to fixtures quickly and without waiting for the water to get hot. This small and easily attachable pump rapidly pulls hot water from a water heater while simultaneously sending cooled-off water from the hot water lines back to the water heater to be reheated. In addition to the convenience of hot water on-demand, the pump conserves water and energy…high on everyone’s agenda these days.

    Bradford White Gas Water Heaters

    We recommend the Defender Safety System® line of water heaters from Bradford White.
