I can honestly say that it has been a great pleasure to install solar thermal systems. Every customer, without exception, has been more pleased with the performance of the system than I would have expected.
In May 2008 we installed a solar thermal system for a retired engineer in East Devon During June he kindly recorded the weather on each day and also took the temperature of the water in his hot water cylinder at 9 a.m., 12 p.m. and 5 p.m. There were only two days in the whole month that he could record as clear blue sky but, nevertheless, he only had to turn his boiler on for one hour on one day for hot water. The solar system met all his hot water needs throughout the remainder of the month.
