A system utilizing solar energy collectors for heating water, which system embodies a piping circuit whereby water from a storage or supply tank is pumped in a continual upward path through the collectors to a peak elevation and thence through sized return piping so as to return with any entrapped air to the storage area, with the return piping being vented adjacent to the storage area to allow escape of such entrapped air to the storage area, with the return piping being vented adjacent to the storage area to allow escape of such entrapped air while the water is circulating through the system and to allow influx of air to replace water in the collectors when the pump is not operating.
