Energy Saving Improvements Details
The original 3 bedroom house was built in the 1930s with solid brick walls but has subsequently had an extension to the side and rear and a loft conversion. It now has 5 bedrooms and an integral garage.
The house was fitted with a solar PV system in 2010 which has a peak output of just over 2kWp with an inverter fitted in the roof room. The owner has a generation meter and remote monitor to check the electricity produced and record past perfomance.
The house has a regular central heating boiler feeding a hot water cylinder and separate ground and first floor radiator circuits. The loft conversion has radiators with thermostatic radiator valves.
Secondary heating is provided by a wood burning closed stove in an existing fireplace opening. The owner burns logs supplied locally.
The extension and loft conversion was carried out around 1995 with insulated cavity walls, floors and roof. The roof construction includes urethane insulation boards between and beneath the rafters to achieve the required U'value. The integral garage is also insulated and fitted with an insulated door to reduce heat loss from the bedroom above.
The energy performance certificate (EPC) for the house indicates it is in band C with SAP73. The environmental impact rating is 72 also in band C and it assumes the house would produce 4.7 tonnes CO2 compared with the national average of 6.0 tonnes.
