immerSUN energy saving device now in stock

Gregor now stocks immerSUN, an exciting new product from Eco4 that allows you to divert excess electricity produced by your Solar PV system (that would otherwise be exported to the grid) to an immersion heater to generate hot water.

The only requirement is an immersion heater with a dedicated circuit to the same consumer unit as your Solar PV system. Excess electricity can also be diverted to other devices of your choosing.
