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.
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.
“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 ...
