If you have an immersion heater, you can now save even more on your electricity bills with Solar Switch technology.
What is an Automatic Solar Switch?
The unit automatically diverts the excess power generated from your solar PV panels, that is not being used in your property, to your immersion heater to heat your water. The unit is wired between the existing immersion heater and the immersion switch. The unit intelligently controls and adjusts the flow of energy to the immersion heater according to the amount of excess power available. This is done via a transmitter installed near to the mains unit which clamps onto the mains unit cable. For example, if the load in the property increases (eg the washer is turned on) the unit will reduce the amount of power sent to heat the water. There’s no need to change the immersion heater as this technology works with any normal immersion rated up to 3kW. The unit is easily installed by a qualified electrician without the need for any plumbing alterations.

Save £s on your electricity bill
For a typical property with a PV array generating a 2kW surplus, you need just 2.5 hours to raise the temperature of a 100 litre tank from 20 degrees to 60 degrees. Based on current average energy prices* that’s a saving, predominantly through the summer months, of up to £250 a year!
