Generate Free Hot Water From Your Solar Panels

SolarSaver™ automatically re-directs excess solar power not being used in your home to heat your hot water for free – saving on your normal fuel costs. Use your boiler as a back-up, or switch it off altogether in the summer!

SolarSaver™ is designed to be used with immersion heaters and measures how much power is flowing in or out of your property and how much solar energy is being generated. Only when you begin exporting electricity will it start to turn on the immersion heater – always adjusting the exact level to use all available solar energy without drawing any power from the grid.

You can turn electric appliances on and off in your house without worrying about it; make a cup of tea and SolarSaver™ turns down the immersion heater as soon as you switch your kettle on and turns it up again afterwards. The unit requires no programming; even the internal clock sets itself.

The SolarSaver™ has a clear colour display showing key generation and consumption power levels. There is a manual overide and if you are on economy 7, SolarSaver™ can also provide a night boost if required.

The example below shows typical energy use and generation for a home on a sunny day with a 4kW solar PV system.

How it works

  • The house used 14kWh over 24 hours.
  • 7 kWh of energy used came from solar power.
  • The PV system generated 21 kWh of energy, of which 14kWh was not used (and went into the grid).

That means that 14 units of energy could have been used to heat hot water – that’s enough to run an immersion heater for 5 hours!

If you have an existing solar PV system, a hot water tank and immersion heater, it should be possible for us to install a SolarSaver™ for just £595 inc parts, labour and VAT.  Payback depends on hot water use but is typically within 2 – 5 years.

    • From the initial call out Solar Voltaics couldn’t have been more helpful or professional. Mark came to visit the house several times and presented us with 6 options for solar panels. The work was prompt and the team polite and helpful. The electrician in particular was brilliant, and very diligent. Despite saying he would clock off early afternoon on the final day, when he discovered a problem connecting the battery he stayed until the job was resolved several hours later. We’ve since had other electricians in to look at other jobs in the house and they have commented on how good a job Solar Voltaics did. When we discovered one of the roof tiles hadn’t gone back correctly, the team came back to address this, despite the works being completed, which was very much appreciated. Would highly recommend.
