Just had a guy round (collared wife at tesco) to see about installing PV, know idea why she invited him round knowing we cannot really have it. Had someone else before and our roof simply isn't big enough. Anyway, he got on about solar thermal for hot water. Works with combi he says, saves you loads he says. He recons 40% saving on gas bill (about £300 per year for us). Plus he says we get paid for it via Renewable Heat Incentive from april when it is introduced (recons £300 plus).
Says £3500 for install, they setup a 10 year payment plan which would cost £46 per month. So IF the system does what he says (300 + 300) = £600 per year. divide that by 12 months = £50. minus the 46 leave £4 per month gain. Not a great deal to be honest. Then this RHI is only for 7 years, so the last 3 years actually cost me. And all this is IF the system does what he says. I've tried doing some research but cannot find much. but everything I have read says these systems can save around £150 per year in gas (this is not the £300 he reckoned). Lastly, be the sound of it, the system will likely be knackered by the time the 10 years is up so I won't reap many benefits after that.
So, am I seeing all this in the right light? Anybody have anything to add? positive or negative.
Thanks
