Save on Your Hot Water Bills for Life!


The immersSUN PV water heating works by monitoring your PV export and when it sees that you are exporting your free energy it re directs the FREE PV energy to your immersion heater or other heating source

Note that the immerSUN hot water switch is a modulating device and will not allow your heating source to import energy from the grid unless you use the built-in boost feature which can be switched on manually or by timer and will switch off manually or automatically like any timer used to control your heaters.


Once your hot water thermostat is up to temperature, the immerSUN solar hot water switch will direct your free PV energy to a second heating source, so you can use your free PV energy to heat a room with a storage heater, Infra-Red Panel or electric under floor heating. The immerSUN PV water heating system checks the first source of heating regularly, to ensure that it is kept up to temperature. You do not need an immersion heater to take advantage of your free PV power from the immerSUN; it will happily work on the other heating sources without an immersion heater as long as they are on their own fused circuit. The immerSUN is NOT a simple solar switch, nor is it a PV relay switch but is a modulating solar water/heater controller.
