The Grant CombiSOL is a cost effective, simple solution to integrating a mains pressure combination boiler with a solar thermal system, cleverly combining the two energy sources.
The CombiSOL works by accurately controlling the outlet temperature of the stored secondary hot water produced by the solar thermal system. If this stored water is not sufficiently hot enough for direct use from an outlet, the CombiSOL directs this stored water via the combi boiler cold inlet to bring it up to temperature before directing it to the hot water outlet.
The installation of certain types of energy saving materials are eligible for a time-limited zero-rate of VAT. Solar thermal technology is one of the eligible products so between 1st April 2022 through to 31st March 2027, the rate of VAT on the installation of a solar thermal system will be 0%.
