Windsor House is a bespoke luxury property in Virginia Water, Surrey. The House required a highly efficient and reliable renewable heating system. The solution Nu-Heat provided had to include boiler back-up, covering the property's heat load in the unlikely event that the ASHP should fail.

Nu-Heat worked with housebuilder AH Lyons to design a bespoke, efficient heating system that included a single Hitachi split ASHP with UFH. Boiler back-up was also carefully integrated with the ASHP, providing an added benefit should the ASHP ever be out of operation.
