Collection: Solar Assisted Hot Water
Solar Assisted Hot Water Systems for Scottish Homes
Hot water accounts for a significant portion of every household's energy bill. Solar assisted hot water systems use your solar PV generation to heat your water for free — dramatically reducing your hot water costs and making your solar investment work even harder.
Scottish Energy Saving designs and installs solar assisted hot water solutions across Scotland, integrating seamlessly with your existing solar panels or as part of a new complete energy system.
How Solar Assisted Hot Water Works
A solar diverter or immersion controller monitors your solar generation in real time. When your panels are producing more electricity than your home is using, the surplus is automatically diverted to heat your hot water cylinder — energy that would otherwise be exported to the grid for very little return.

Frequently Asked Questions
Do I need a special hot water cylinder?
Most standard hot water cylinders with an immersion heater are compatible. Our advisers will confirm suitability during your free survey.
Can I still use my boiler?
Yes — solar assisted hot water works alongside your existing boiler. The solar diverter simply tops up your hot water using free solar energy first.
How much could I save?
Savings depend on your solar system size and hot water usage, but many homeowners significantly reduce or eliminate their hot water energy costs during summer months.
