Grant WinterSol

Grant WinterSOLThe Grant WinterSol has been designed to provide homeowners with a fully heated cylinder of hot water during times when there may not be sufficient solar (or heat pump) gain, therefore ensuring hot water demand is satisfied.

During the winter months, for example, 150 litres of hot water from a 300 litre cylinder may be insufficient. By fitting the GrantWinterSol, a simple summer/winter switch can be operated by the customer, allowing the central heating boiler to heat the full contents of the cylinder. When solar gain is restored, the switch is set back to summer mode for maximum efficiency. This unit does not directly prevent solar thermal or heat pump systems from operating as it only energised during the customers normal programmed hot water period.

It is important to note that like all components fitted to potable water, there is a risk of limescale contamination in hard water areas. Precautions should be taken to prevent limescale build up in this valve set. Failure as a result of limescale is not covered by the guarantee.
