“We are generally pleased with the energy saving measures we have introduced. We are particularly pleased with the air-source heat pump that provides our hot water; with the wood burning stove; with the added insulation and with the kitchen appliances including the boiling water tap. The argon-filled double-glazed windows and doors also seem to be very efficient during cold weather (the door and window frames get colder than the glass!).“ Homeowners
