June 17, 20224 yr Hi all, Just to briefly introduce myself: We completely refurbed a 1960s bungalow 10 years ago, building a SIP two storey extension, more than doubling its size, adding cavity and external wall insulation to the original bungalow at the same time. We installed underfloor heating driven by a Mitsubishi Ecodan 85 ASHP. We also added 4kW of PV panels, solar hot water, MVHR, and rainwater harvesting. We did all that back in 2009-10 and at the time I got a lot of help from the old Navitron forum. Since when we have been enjoying the house and been very pleased with the results. I have joined Buildhub now because: Whilst originally the PV FITs were covering our electricity costs, that's a long way from true now. So I am looking at what further efficiencies we might make. I think we will do another house project in a few years, maybe a new build but we'll want it to be as efficient as possible, so I could be seeking thoughts, ideas etc. As an aside I am secretary for our small village hall, which is a converted stone 19th chapel. The heating costs have gone through the roof (as does most of the heating tbh!) so I might be looking for any ideas members have about managing heating costs for a building that is unoccupied most of the time. I apologise that it looks from that list as though I am just on the take but hopefully, with our experience of a major eco-rebuild I can offer some ideas in return. Anyway, that's me introduced!
