Looking for a new heating system?
Find the perfect system in 3 simple steps
Solar thermal systems are systems which use solar collectors to harness the free natural energy provided by the sun and convert it into power. Adding a solar thermal system to your heating system will provide you with domestic hot water heating backup and central heating backup. In doing so, you will be able to look forward to lower energy consumption and in turn, lower monthly energy bills.
Solar thermal systems work by collecting energy from the sun using solar collectors on the roof of your property and transferring this energy into heat. This is achieved by using the sun’s rays to heat a fluid mixture of water and anti-freeze. The heated fluid mixture is then pumped to a heat exchanger in your home’s water tank and used to heat the water contained within the tank. Once the heat has been released from the fluid mixture, it is then pumped back to the collectors for reheating.
A solar thermal system consists of a number of components:
Flat plates can be integrated into the roof your property and can be coloured coded to match your roof tiles. Cheaper to install than tube collectors, they are the ideal solution for south facing pitched roofs.
Tube collectors offer greater efficiency and increased flexibility as they can be rotated to face the sun. Tube collectors are suitable for installation on pitched roofs, flat roofs and on walls. Tube systems can also be easier to install as the individual tubes can be installed separately.
Our range of Vitosol flat plate collectors are made from light and translucent anti-reflex glass. With long term durability and reliability, they also feature a seamless edge strip for weather and UV resistance.
Whilst the UK does not benefit from all-year round sunshine, there is enough sunshine available for domestic hot water, as our solar thermal systems will work in cloudy and overcast weather.
With a Viessmann solar thermal system, in addition to your boiler, the solar panels are also connected to a dual coil hot water cylinder. If the heat from the sun is not sufficient and the water temperature gets too low, the boiler will be fired to heat the water.
Using a solar thermal system, you could save up to 60% on your domestic hot water energy costs.
Whilst our solar thermal systems utilise solar panels which will need to be installed on the roof of your home, planning permission is usually not necessary unless your home is a listed building or it is in a conservation area.
Utilising the highest quality materials, we have been designing and manufacturing solar panels for more than 30 years. Continuously proving themselves in terms of efficiency, performance and reliability, there are more than 1 million Viessmann solar systems installed worldwide.
The use of solar energy ranks among the most environmentally responsible energy conversions imaginable. In addition, the government is currently committed to investing in these kinds of systems.
