Geoff lives in a well-insulated home (R30 walls) with a robust, 90 evacuated tube solar hot water array that provides 90% of his year-round domestic water supply and a portion of his space heating needs.

He primarily heats with wood, with a resistive electric boiler as backup.

He recently added a solar photovoltaic array to completely offset his home’s carbon needs!
