Turnkey installation of a 199kW biomass boiler in a listed building in South Scotland. The project connected two houses and a swimming pool and included a substantial upgrade to the internal secondary side heat system. The chip hopper was custom designed. This heating upgrade has allowed for a greater use of heat in the building and has transformed the antiquated heating system making it easier to operate. The secondary side heating system now has a simple switch system allowing additional hot water storage when the house is fully occupied.
