“ I  have had Solar Options solar hot water evacuated tubes on my cow-shed for a number of years. It was Gerry’s first project on a Dairy hot water system for plant and vat wash and he seemed to get it dead on with the amount of tubes to heat the cylinders above and beyond 8 degrees, which is needed. He has been very approachable and only too ever to iron out any problems we have had in understanding the system.”
