    • Considerations


      Up front purchase costs are usually lower than other types of units

      Lower installation costs with no upgrade of gas line required

      Delivers hot water faster, as the water is stored ready for immediate use

      5 star energy efficient models also available


      Tank size takes up space

      Heat loss from the tank, whether the water is being used or not

      Not as energy efficient as a solar or continuous flow unit

    Always use a licensed plumber when installing a hot water system.

    The Thermann 4 star Gas hot water system is suited to families of 3-5 people. With an adjustable thermostat for safety and efficiency, it allows you to be in control of your operating costs and performance.

    • 4 star efficiency
    • Full mains pressure taps
    • Small footprint - easy replacement
    • Includes a Pressure and Temperature Relief (PTR) Valve

    How it works

    Step 1:
    Coldwater enters through a pipe at the bottom of the tank.

    Step 2;
    A gas burner located under the tank begins to heat the tank.

    Step 3:
    The hot exhaust gases from the burner travel up the side of the tank further heating the water to the desired temperature.

    Step 4:
    The hot water progressively rises to the top of the tank. When a tap inside the home is turned on, the hottest water then exits at the top of the tank where it flows to the user's location.

    Step 5:
    To ensure the water stays at the right temperature, a thermostat constantly measures the water temperature and turns the burner on or off as needed.
