The immerSUN PV water heating system is a simple and straight forward option to heat water and your house with solar PV panels.

If you have a Photovoltaic (PV) system you have probably noticed that you are exporting to the grid over 50% of your energy.

Now with the use of an immerSUN you can have PV Water Heating, – you can ‘heat your water for free’ using your own green energy. Surplus energy from your PV panels can be diverted to heat your water using your immersion heater, turning your PV system into a solar hot water heating system.

The immerSUN PV water heating system is a simple and straight forward option to heat water and your house with solar PV panels. In essence the immerSUN hot water contoller is a solar water heater.

Additionally the immerSUN can cascade the free energy to a second heat source; e.g the immerSUN can divert your free PV energy to storage heaters, electric underfloor heating or electric panel heaters once the first source is satisfied.
