    • Considerations

      Pros

      Save space with small footprint mounted on your wall

      They heat water as you need it, so you will never run out of hot water

      Controllers can be installed to accurately deliver required water temperature

      Cons

      Higher up front cost for equipment and installation

      Less efficient in winter

      Tubes are more effective when installed on a north facing roof to maximise the efficiency of the sun

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

    Thermann Evacuated Tube Solar gas boosted hot water systems offer the best of both worlds. While the tubes harness the suns energy to heat your water, you also have the confidence of an energy efficient gas continuous flow hot water system to provide back up if needed. You'll not only have peace of mind, you'll also reduce your running costs.

    • Cost effective to run

    How it works

    Step 1
    The sunlight strikes the dark absorber coating inside the evacuated tube.

    Step 2
    The heat pipe transfers the heat up to the copper header pipe location in the insulated manifold box.

    Step 3
    A circulator moves water from the storage tank to the copper pipe warming the water. The solar heated water is then pushed down into the storage tank for use. Anti-frost is built in to the Thermann system to ensure solar hot water can be provided even in cold regions.

    Save with Solar

    When it comes to lowering your power bills, Thermann is the right investment choice for the longer term. When paired with the solar tube components, it provides lower running costs, making it the smarter, more sustainable and affordable alternative to the traditional systems. It's also better for the environment. In times of high sun exposure, the system will use 100% of its energy from the sun, using almost 0 mains electricity.
