SOLAR WATER HEATING FOR YOUR HOME
Solar thermal energy is a little bit different from solar PV systems, which use light from the sun to generate electricity. A solar thermal system instead uses slightly different solar panels that collect heat from the sun, and use this to heat water stored in a hot water cylinder.
How a solar thermal water heating system works
Solar thermal collectors can, much like solar PV panels, be placed on your roof, or on the ground – wherever they will be best exposed to sunlight and heat. Fluid is circulated through the collectors to become heated, and is then pumped to a water storage tank.
The solar-heated water in the hot water cylinder can then either be fed directly to your heating system, or can be further heated by a boiler or immersion heater to reach the temperature you need.
You may wonder why solar thermal is useful if you still have to use your boiler at times. However, your boiler will not need to be in use for anywhere near as long as if you didn’t have the solar thermal heater, saving you money on your bills through reduced usage.
Using a solar thermal system with an air source heat pump
A solar thermal system makes an excellent partner for an air source heat pump. An air source heat pump takes heat from the outside air and brings this heat into your home, where it can be further heated by your solar thermal system.
