The diagrams to the right represent an example of an advanced solution for domestic water & central heating production and also a general illustration. Hot water is produced by the solar system which is integrated with the system boiler for non sunny periods. Our condensing system boiler, as standard, is fitted with an integral 3-port control valve to divert the primary water between the cylinder and the central heating system, saving on external pipework and controls.
