Solar thermal heating for domestic hot water is the fastest growing renewable technology across Europe. Using radiation from the sun, a sophisticated solar collector is used to transfer the maximum amount of energy possible in to a fluid, which runs through the collector and which is then used to indirectly heat water in a storage cylinder.

As solar thermal technology does not rely on sunlight but on solar radiation, it can work as efficiently in our climate to provide around 50-70% of annual domestic hot water requirements.

 Vaillant AuroTHERM Exclusive VTK 570/2 Solar Heating System – Vaillant Renewable Energy Collection

Vaillant AuroTHERM Exclusive VTK 570/2 Solar Heating System at PlumbNation is a renewable energy source from Vaillant AuroTHERM Collection which contributes to the reduction of CO2 emissions from the home.

Solar water heating systems use solar panels, called collectors, fitted to your roof. These collect heat from the sun and use it to warm water which is stored in a hot water cylinder.

A boiler or immersion heater can then heat this water further until it reaches the temperature set by the cylinder's thermostat. (This should be set at 60 degrees centigrade.)
