Our solar hot water panels were deteriorating badly but the bloke found some replacement ones that he thought would be useful. We found the contact details for Hot Water Hotline who provide reconditioned solar Panels. Mike gave some very useful advice over the phone, then came and checked to see if they were ok. He then removed the old dodgy panels and installed the 'new' ones for us, for a reasonable price and giving us peace of mind that it was done right.
