Common solar hot water myths explained.
Even when partially overcast, the UK receives enough diffuse solar radiation to preheat domestic hot water.
They offset the cost of gas or electricity, and correctly maintained systems can have an operational life of over 20 years, adding property value.
Systems can be designed for any quantity of hot water, though a slightly larger cylinder is typically needed.
Energy collected during the day heats the water, and a well-insulated cylinder keeps it hot for use at night.
Diffuse radiation still provides solar gain on sunny winter days, reducing the energy the boiler needs to use.
A twin-coil cylinder typically costs only 20-30% more, and roof-integrated collectors can offset roofing costs; an average 2-panel system costs around 2,000-3,000 plus installation.
Hot water heating accounts for 20-40% of home energy use, so switching to solar can cut carbon emissions significantly.
Modern systems can be roof-integrated to sit flush like a skylight.
Systems need extra space for safety devices, but experienced installers can design one to fit the space available.
Most solar hot water systems can be installed in two to three working days, depending on requirements.
