adding that the high-temperature heat provided by the solar collectors is transferred to a hot water loop, connected to the PCM storage tank, where the circulated water heats the PCM tubes.
“This work focuses on the Italian version of the RESHeat project,” the scientists said, noting that the proposed system adopts a hot water storage tank instead underground heat storage unit ...
Installing solar power ... A normal water heater, at least one based on electric resistive heaters, attempts to maintain a small range of temperatures within the insulated tank.
