Produce your own hot water day and night

Hot Water Solar Panels (also known as thermodynamic solar panels) can heat water up to 55°C, to be used for domestic hot water or for heating your radiators. They work all year, day or night, and in any weather.

How do they work?

A special, extremely cold fluid is circulated throughout the panels, which absorbs heat from the surrounding atmosphere. When it leaves the panels it enters a compressor. The high pressure in the compressor turns the fluid into a hot gas. This hot gas then flows around cylinders and heats your water. After heating up the water, the gas goes through a valve where it expands, cools, and returns to its original state. The fluid flows back into the panels, and the process starts all over again.

They don’t have to be in direct sunlight to work. In fact, they will work anywhere at any time of day, as long as the outside temperature is above -15°C.

How many panels do I need?

For most households 1 or 2 panels are enough to produce all of your domestic hot water (i.e. what comes out of your taps and shower). The system also includes a hot water cylinder.

4 panels are enough to heat an average house up to a comfortable temperature — even in the middle of winter.

How much can I save?

For a typical gas heated home, you could save 80% on your heating bills.
