Solar Thermal Installation
Our house had been refurbished during 2008 and at that time a new hot water storage cylinder was fitted. The hot water cylinder was equipped with twin coils but only the lower coil, which was connected to the gas central heating boiler, was used initially.
In the spring of 2014, CTD were approached to install a solar thermal system to supplement the domestic hot water heating system. The work necessitated installing 2 solar panels on the south-facing roof and connecting these via a sealed pumped system to the secondary coil on the hot water cylinder. A controller was also installed which managed heating of the hot water. In brief, whenever the temperature difference between the solar panels and the water stored in the cylinder exceeded around 6degC, the solar pump would circulate hot fluid produced in the solar panels to the cylinder.
CTD installed the system in June 2014 over a period of 2 days. We were surprised and delighted at how much solar energy was available to heat our domestic hot water; in fact, the boiler was hardly used at all during the summer months.
We were pleased with the work that CTD carried out on our behalf; the plumbers and electricians were extremely competent and installed the various components in a neat and orderly way.
Based on our experience, we would have no reservations whatsoever in recommending CTD for similar installations.
