Bunsen Air Hybrid

Water & Heating System

You already have a working home heating system – but you would like to use a low cost electric heater renewable heat source. The Bunsen Air Hybrid uses the Tank-in Tank system to use renewable technology to heat your hot water and space heating water, making your existing natural gas heating system for homes a back-up if additional demand is required.

The Bunsen Air Hybrid with its solar hot water panels is non-invasive to your existing heating system – so you keep the radiators you have already (unless you fancy an upgrade!).

Day & Night Hot Water & Heating From Nature’s Free Energy


The Bunsen Air Hybrid uses a Smart cylinder to allow the Bunsen Air units to heat both your hot water and your central heating water.

Your existing heating system becomes a back-up to the Bunsen Air, kicking in if the heating demands exceed the Bunsen Air capacity.

How Does It Work?


When the system first turns on we use your existing heat source i.e. combi boiler that will heat the cylinder to a pre-set temperature. With the Smart Tank-In-Tank cylinder heating the cylinder with your existing heat source is extremely fast. Once the hot water reaches it target temperature your existing heating source turns off and the Bunsen Air system takes over sustaining the temperature throughout the day or night at a much lower running cost.

The Bunsen Air Hybrid systems are a very low energy heating system, so you run your heating at a lower temperature than when using fossil fuel heating. If you do need that extra boost, then your existing boiler will kick in to help out.
