The house was built in the 1930’s, but when Mary and John moved in, they were determined to lower their energy footprint. Insulation in the loft and an internal wall insulation have reduced heat loss, and roof ‘lanterns’ make use of natural lighting.

A 25 kW biomass pellet stove provides hot water and cooking, and new double glazing has sustainable oak frames.

Electricity to the house is provided by a 100% renewable supplier Octopus, on the Flux tariff.

Solar photovoltaic panels using SolarEdge technology to optimise output when the panels are partly shaded. The electric car is charged with renewable electricity at night using off-peak rates.

A Tesla Powerwall battery storage was installed several years ago to make use of electricity generated during the day, through the night. The Powerwall battery is controlled by an app that allow it to charge and discharge, buying and selling electricity at the most favourable rates, thus reducing the overall energy cost.

Last summer a bank of solar thermal ‘tubes’ was installed reducing the energy requirement to heat the domestic water. The immersion heater is controlled by a switch which can be turned on or off depending on a timing sequence set by a smart phone app.  This allows best use of energy in the spring and autumn when solar energy is reduced.
