Many homeowners are discovering that combining solar energy with an air source hot water cylinder can deliver even greater energy savings and independence from the grid.
How the Combination Works
A cylinder with built-in heat pump draws renewable heat from the air to warm water. When paired with solar panels, the electricity generated by the panels powers the heat pump — meaning your hot water is effectively heated by the sun, for free.
Benefits of a Solar-Compatible System
- • Lower bills – use your own renewable power to heat water.
- • Year-round performance – air source technology works even in winter.
- • Reduced carbon footprint – combine two renewable sources for maximum impact.
- • Flexible installation – ideal for homes already investing in solar PV.
Is It Worth It?
For most households, the combination pays off quickly. On a typical overnight tariff, a 250L cylinder costs under £1 to fully heat, and with solar input during the day, the cost can drop even further — often close to zero on sunny days.

Explore the Air Sourced Hot Water Cylinder range at Gaia Smart Energy. Each model is designed to work seamlessly with solar systems, giving you cleaner, cheaper, and smarter hot water all year round.
Traditional systems often require complex pipework or boiler integration. Air source cylinders with built-in heat pumps are easier to install, need only water piping, and come in sizes 80–250L. They’re also compatible with solar for even greater efficiency.
