A solar thermal system needs to feed into a twin coil hot water cylinder, so that it can be used in conjunction with another heat source. If your home or building uses a combi boiler, there will be no existing hot water cylinder, so a new high-pressure cylinder would need to be fitted. These can fit easily into an airing cupboard, loft or utility space, and provide the dual benefit of fuel savings from solar thermal and a better flow rate from the high-pressure cylinder.
An old or single coil hot water cylinder will need to be replaced with a twin coil cylinder. Solarsense can identify and provide all kinds of heating upgrades necessary for the installation of a solar thermal system and can supply these as part of an installation package.
