Should I consider using solar energy?Firstly, because by reducing carbon dioxide emissions, you can rest assured that it’s better for the environment and you will also be helping to conserve the world’s rapidly diminishing supplies of gas and oil. Secondly, utilising solar energy for hot water will help to reduce the impact of rising oil and gas prices and means that you won’t be so reliant on these conventional fuels. Thirdly, installing a good solar system can add value to your property.

How does a solar DHW heating system work?The principles are quite straightforward. Solar collectors absorb energy from the sun to heat a fluid that is pumped in a sealed circuit to an indirect coil in a water cylinder to heat the domestic water.

Where are the collectors fixed?Vaillant’s high performance solar collectors are easily sited on pitched roofs, flat roofs, or in roof. Ideally the solar panels should be oriented to face south, but they will work with a small loss of efficiency sited between 30 degrees east and 40 degrees west of south.

Do I want vacuum tube or flat plate collectors?Vacuum tube collectors offer the highest operating efficiency all year round and, due to their low weight and smaller dimensions, offer easier installation and handling. Flat plate collectors should be used when efficiency during autumn, winter and spring is not so important and in areas where a tough collector is preferred.

Surely there is not enough sunshine in this country to make it work?As the panels work on diffused solar radiation as well as direct sunlight, they will even generate small amounts of energy on partially cloudy days. This lowers the energy required from your boiler. The DTI has calculated that there are sufficient solar radiation levels across the whole UK to provide useful energy. In areas with lower solar radiation, the number of collectors can be increased to maximise solar energy usage. In addition the design of Vaillant’s tube collectors ensures that they capture solar radiation at a wide range of angles making them more efficient than other designs during spring and autumn.

Vaillant has always been at the forefront of technological progress in the heating and hot water industry. We’re leading the way again with the development of advanced renewable hot water systems that capture and convert the sun’s energy.

While solar heating systems have come to the fore of late with global temperatures continuing to increase and traditional energy resources in decline, Vaillant has been investing for many years in developing these renewable energy solutions.

The result today is a cutting edge solar system that sets the standard to which all others aspire. We’ve patiently and painstakingly developed a solution that meets the precise needs of installers, specifiers and homeowners – both now and in the future.

More importantly, perhaps, it’s a complete solar system where each class-leading component – solar collectors, storage cylinder, high efficiency boiler and controls – comes together into one seamless solution to achieve maximum efficiency, exceptional performance and outstanding reliability.
