[QUOTE="binky, post: 523308, member: 490"] you make some very valid points that I would agree with, in particular Solar Thermal - I've met customers with thermal panels in place and extolling their virtues long before PV became a thing. PV does have the advantage of being more flexible in application though. A bit of both is always good. Jumpers, marvellous things, it's only the youngsters that have grown up with central heating :D. I've had a few customers who wanted to go 'off-grid' the numbers just don't stack up unless you like living a bit like a hermit in the middle of nowhere - numbers will have improved now of course. Ultimately, reducing energy use is the way forward, a friend has a 'passive haus', he has a 1 kw electric heater for the occasional cold weather as a back up, which he reckons only really gets used if they go away for week in winter. He has no central heating system what so ever, a major cost saving and maintenenace free of course! He does have a mechanical ventilation system for the whole house, which he switches off in warmer weather. Installing insulation can be a pain in older properties, this is part of the reason you see houses flattened and completely new houses built in their place. With VAT on a new buid being 0% in can be cost effective and you get a modern glass box if that's your thing! Batteries are getting cheaper and do payback more than they cost due to cost reduction and improved tech, but they still aren't a 'no brainer' option. 20 year payback? 15 years ago that was probably true, however, solar panels have dropped an awful lot in price. I've just priced a simple to fit 8kW system fat £5500, when I started with solar it was £12-14k for 4kW. Not sure about other tech as I don't fit that. [/QUOTE]
