So, after a few teething problems (an airlocked panel- slight modification to include air bleed valve, and a pin-leak in one joint) The panels are heating our water!
Thought I would share the cost of the system too so people can decide if it’s worth it or not….
Excluding the roof itself (i.e the structure and polycarbonate roof sheets), the aluminium (reclaimed from our old mobile home), the other bits and bobs like gas/solder/flux… the plumbing bits cost a total of £170.
Quite a lot of time has gone into the fabrication and installation, and we already had the twin coil cylinder installed so this perhaps is not a true reflection of a retrofit system, but my feeling is that it will VERY QUICKLY repay the investment.
There is a point also I should make about this type of installation- it will not pass muster with building regs and SAP reports as it does not have HETAS approval or efficiency ratings, and is not installed by a qualified engineer- so clearly it’s not worth doing….? A rant for another day methinks!
Anyhow, hope you have found this interesting.
Till next random post….
