In accordance with the present invention, a system for collecting solar heat that is much more efficient than currently available systems may be constructed by using electronic components that are currently widely available and low in cost. To that end, a programmable logic circuit receives data provided by temperature and water volume sensors and next actuates electromechanical valves, water pump and heating electrical resistor in accordance with pre-programmed instructions, such that the efficiency of the residential/commercial or industrial solar heat collection system is significantly enhanced. The programmable logic circuit may be a set of logic keys, a CPLD, an FPGA associated with a CPLD or an RISC, CISC or ARM technology microprocessor. The water volume sensors are key-locked buoys and the temperature sensors comprise thermocouples. The control interfaces of electromechanical valves, water pump and electrical resistor are constituted by optoisolators. |
