Posted By: chipedwoodAlso I wouldn't recommend any solar equipment in the UK as it is not efficient enough to pay for itself even in the long run.
Posted By: StuartBstephendv - 6.7kwh seems very high for a 2 bed house! We are currently burning 7.9kwh in a not particulary efficient 4 bed home, I would hope to get this down considerabley with a new build.
Posted By: StuartBPaul, you are correct, excuse my maths. It was 70,000kwh for the year.
Posted By: StuartB4,681mWh for electric and 22,300 kWh for gas which is how I got to 70,000 for the year. Does this sound excessive/incorrect anyone?
Posted By: StuartBCanada is definitely somewhere I could live. The quality of life is so much higher than the UK. Lovely hot summers too which I guess helps you get through the freezing winter!
Posted By: tonyInsulate and get airtight then work out heat loss then think about how much solar heat you can use then think about an inter-seasonal thermal store (needn't be expensive) then see what you maximum base load will be then look at reducing that then size your generation or storage capacity.
Posted By: MarkHpmcc - we chose to have Warmcel blown behind our plasterboard between the timber frame. We already had 25mm of EPS (and then a 75mm gap). This seems to have been effective (we think the walls now have a u value of 0.35 or better), and although just as messy as ripping off plasterboard to fill the stud work with rigid insulation, it was about 20% of the cost if my memory serves...
Posted By: StuartBIs it possible to be 100% off grid for a maximum capital outlay of £15k? Location - rural, exposed south facing half acre plot in Scotland with am average wind speed of 6.1.What renewable technology would you use to provide all your heating and power needs for a 4 bed house? If it can't be done for less than £15k how much do you think it would cost?

Posted By: fostertomPosted By: renewablejohnWhat renewable technology would you use to provide all your heatingI answered you that but you poured scorn on it, poss because it wasn't a bolt-on 'technology' but something more integral in the (re)design of the house's fabric.
