Solar Thermal Systems generate free hot water from the power of the sun, saving you hundreds of pounds each year. Solar Thermal Systems are a sensible and sustainable alternative to heating domestic hot water water. This is particularly ideal where you are off the mains gas network and paying huge oil or solid fuel bills.
HOW DO SOLAR THERMAL SYSTEMS WORK?
Solar Thermal systems provide hot water from the heat of the sun providing on average 60% of your families hot water needs across the year. Thermal collectors, held within the panels on a roof, harness the suns warmth to heat up fluid in the solar collectors. This fluid is then circulated through a coil in the hot water cylinder to heat up the water in your tank.
HOW MUCH HOT WATER CAN I PRODUCE?
For large parts of the year, a solar thermal system should meet ALL of your hot water needs. This will greatly depend on the size of the system installed and how well insulated your home is. Even during the winter, the water is often heated above standard mains temperature meaning that your conventional boiler doesn’t have to work so hard to heat your water.
WHAT ARE THE FINANCIAL BENEFITS AND INCENTIVES?
Solar Thermal installations benefit from the Renewable Heat Incentive (RHI). This means that the government will pay you a subsidy to generate your own hot water for 7 years paying back a proportion of the installation. Solar Thermal systems are often installed in conjunction with a second renewable energy heat source such as biomass or heat pumps. Both of the technologies then feed in to one thermal store via separate coils which are then backed up by an immersion heater should a boost be required. A well maintained Solar Thermal System can last for years and we have maintained systems up to 30 years old. We recommend that your Solar Thermal is serviced every 2-3 years. We carry out this service for many customers including systems installed by other companies.
