Solar heating using a combi boiler

KEY: 1 Cold water supply 3 Hot water taps 5 Storage tank 7 Solar panels 2 Boiler 4 Controller 6 Pump Water from the mains supply (1) enters the hot water tank (5) and is stored until it reaches a usable temperature for delivery at your taps (3) A pump (6) operated by the controller (4) circulates fluid through pipework up to and from the solar panels on your roof (7) heating the tank (5) Normally water would bypass your combination boiler as long as it is up to the required temperature on overcast days or in times of high demand for hot water your combi boiler (2) would light to make up any shortfall for your hot water requirements. Its very simple but if you are still a bit unclear then please have a read of our Frequently asked questions. If you have any questions then please Call us on 020 8308 0708 or Email us. The next step - You will need to have a "suitability survey" carried out by one of our authorised engineers. They will then be able to explain what will need to be done to your existing system and the optimum number of solar panels required.
