Divert the excess energy you generate into FREE hot water

The immerSUN monitors the electricity which is about to be exported to the grid and automatically directs any excess generated electricity, not used by the house, to the immersion heater in the hot water cylinder - heating your water for FREE!


If the load from the house increases, eg. the washing machine is turned on, the immerSUN will reduce the amount sent to heat water to help you maintain independence from the grid.

Use your free electricity when you’re out.

Increase your return on investment

When using the immersun to heat water with PV, immerSUN estimate you could achieve a payback of 3-5 years.

Uses your existing equipment

Add immerSUN to your solar PV system

TaylorMade Solutions can install an immerSUN unit at the same time as your solar PV system (our electrician is already there), cutting install costs and giving you maximum value for money. If immerSUN uses your existing immersion heater, there's no need for any plumbing work.

Is my hot water system suitable?

We can advise you at time of survey whether the immerSUN unit can be fitted, so if you're unsure please ask.

Generally speaking, immerSUN can be fitted if you have a hot water cylinder with an electric immersion.

If your water is heated by a 'combi' type boiler (no cylinder), immersSUN is not suitable.
