Solar Immersion Switch – Costs and Benefits

Solar panels

With the immerSUN control unit, only the electricity that would have been exported to the grid is used by the immersion heater. This device means that you don’t have to be at home on a nice sunny day to enjoy the benefits of free electricity. When you have any ‘spare’ electricity, you can enjoy a free tank of hot water.

The unit does not affect your feed in tariff payments, it will increase your return on your investment quicker. This could mean that your boiler remains off during the warmer months reducing your energy bills significantly. The payback period for is usually 3-5 years.

The units have an LCD display screen which tells you how much energy you have saved.
