Further Information & Advice

Solar thermal evacuated tube collectors can provide a percentage of your domestic hot water needs, the remaining shortfall is made up by your traditional gas boiler (or other heating system). An evacuated tube collector system is made up of the following main components: solar evacuated tube collector(s), twin coil cylinder, pump station and control.

Vokèra advises that a solar evacuated tube system is connected to a twin coil cylinder and a system or open vent boiler. This allows the solar energy collected to be stored in a cylinder for later use, the boiler also acts as a top up, when the solar evacuated tube collector is not able reach the desired temperature..
