This house was built in 1972 with double walls and cavity insulation. Celia and Charles have installed PV, hot water thermal solar, and a battery system to store electricity. The 2.7 kW Solar Edge PV panels produce electricity which is stored in a 2.4kWh expandible battery system in their roof. Both systems can be monitored through wifi, and the installer has set this up as a test rig to find out how well it works. Hot water from the solar thermal panels is stored in an efficient tank, and benefits from a Renewable Heat Incentive subsidy. The house is heated by a single efficient woodburning stove, with a clay chimney breast designed to provide thermal mass and therefore store the heat. A sterling engine drives a fan to distribute the heat around the room and into the stairwell. The conservatory on the South wall provides passive solar heating. The owners' philosophy is to use as much recycled and local material as possible, with an emphasis on health. Clay paints and Natural fibres are used whenever possible, and furniture, kitchen and even bathroom fittings are recycled or repurposed. High efficiency white goods and future-proof design of the kitchen ensures ongoing maximum ergonomic convenience.
