Between the solar collector array and the cylinder, insulation of pipework is also important. Solar Craft use well-insulated, stainless steel, DN16 flexible piping for solar thermal systems to save time, reduce the cost of installation and most importantly to ensure a leak-free solution. The HeatCon Duo-Flex stainless steel solar pipe is designed to withstand high temperatures associated with solar heating system. This solution contains two flexible stainless steel pipes inside EPDM closed cell insulation, along with an integrated sensor cable for monitoring solar panel temperature with a solar controller. Our pipe provides excellent heat retention and insulation, optimizing the performance of solar water heating system.
