Steve Dyck of Guelph Solar Mechanical provided consultation and installation services for an evacuated tube solar hot water system for my home-office in Fall 2009. I was very happy with Steve's technical review of various components and design considerations that I had proposed. Steve provided critical thought and modifications to equipment required for my domestic water and space heating application. I have also been very pleased with the performance of the system's performance which has seen 100% of our domestic needs satisfied while a reasonable contribution to space heating via infloor hydronics and hot water radiators was observed in winter months.
