immerSUN: use up ALL your PV/turbine electricity

Do you have PV panels on your roof?
Do you run a windturbine on your land?

If Yes then you must get an immerSUN.

You probably know the frustration of generating renewable energy, but then seeing most of it flowing straight out of your house to the grid. Sometimes it is possible to soak up some of this energy by turning on the dishwasher, the washing machine, the immersion heater, etc, but its a tricky business: you can never use up all of the energy or you may use more than is generated and incur high cost of day time electricity, you are not always home and even if you are you can only reduce the flow of your energy into the grid.

The immerSUN, on the other hand, never sleeps, works every single day and every single hour, monitors the flow of electricity and captures every single Watt of energy and makes it work for YOU through an immersion heater and/or night storage heater or similar.

The immerSUN monitors the electricity which is about to be exported to the grid by your renewable energy device(s) and diverts it to the immersion heater. It then automatically directs any excess generated electricity, not used by the house, to the immersion heater in the hot water cylinder, storing the excess energy as heat.

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.

When your water is hot, immerSun can divert the excess electricity to a night storage heater or any other electrical load of up to 3kW capacity.

Use your free electricity when you’re out: Our energy saving device for solar or wind directs excess electricity to the immersion heater

Increase your return on investment: When using the immerSUN to heat water with PV we estimate you could achieve a payback on the whole system of 3-5 years instead of the usual 7-10 years. Wind turbine will achieve much faster payback.

A controller that is simple to install: The immerSUN uses your existing immersion heater to heat water

Use your free energy and still get paid: Use up to 100% of your generated electricity and still get 50% export FiT

Higher efficiency reduces your energy bills: By using more of your free electricity you will make substantial savings

Built in hot water timer with added Boost function: You have total control over your hot water with our advanced features

The immerSUN measures and records energy applied to the immersion heater. As only the renewable energy is counted this is effectively saved energy.

You can view savings made for today, the week, the month, the year or total savings.
