Just turn up
Andy welcomes you to his 4-bed extended detached home with swimming pool.
Solar PV, blown cavity insulation, heat pumps, extra loft insulation, LED lighting, 300 litre hot water storage tank, Solar PV diverter to put excess PV power into immersion, double glazing, hi-spec extension on northwest face of house, foil insulation under wood floor on concrete beams, optimised 2nd heat pump for swimming pool heating and rainwater capture. Started to use insulated boards on inside of external walls, when redecorating rooms.
Motivation to retrofit:
I have always been interested in energy efficiency and studied the subject as part of Environment Sciences BSc at UEA, graduating in 1979 - ahead of the times
£500 for loft and wall insulation, £10,500 Solar PV (funded by 25-year scheme), £10,000 ASHP - £7,000 grant, extension £35,000, underfloor foil £200
Approximate energy savings:
Reduced electricity consumption from 17 to 11MWhpa. ASHP in 2015 saved £100pm oil bill for extra £60pm electricity.
Improved comfort, all-day warmth, affordable swimming pool
Original house has suspended concrete beam ground floor - noticeably colder under foot than the new extension in winter. I would like to insulate underneath it, using blown fibres but cannot find information to support. I am concerned that a solution needs to deal effectively with radon gas - if that is a real risk for my location.
Solar thermal considered for garage roof, to heat hot water. However, I now have a diverter to put surplus solar PV into hot water immersion. This is not an optimum solution from an overall (public) energy efficiency perspective but it is effective for me. Diverted 535kWh since Dec-21, despite pool using most of solar PV in summer.
