SOLAR hot water harnesses clean, free solar energy to heat your domestic hot water quickly and efficiently, even on cloudy days you will get good solar gains. Evacuated tubes have a vacuum that acts as a super-efficient heat trap. Heat pipes located within the evacuated tubes then conduct the heat trapped within the tube up to the header to heat water.
The copper heat pipes are also evacuated and attached to aluminiumnitride heat fins to maximize solar energy absorption and heat transfer. On a sunny day, these heat fins and heat pipes can exceed 150°C very quickly.
As the heat is conducted to the top of the solar panel, a solar controller senses the rise in temperature and moves water to the panel to be heated. The heated water is then circulated back to a storage hot water cylinder.
A circulating pump moves the water to and from the panel. The system’s solar controller and circulating pump together with any auxiliary heating keeps water in the hot water cylinder at a constant temperature – ensuring you have a reliable supply of hot water heated by the sun.
