How will a solar panel feed in to my existing heating system?
You need to have a conventional water heating system as well, such as a gas, oil or wood fired boiler, to top up the heat from the panels when necessary and provide hot water and space heating in the winter. You can add solar panels to most existing hot water systems, though you will usually have to add an additional ‘pre-heat’ water tank or change your existing one to a twin coil cylinder. You may need a pump to circulate the water, and some regulating equipment to prevent overheating.
