Solar water heating. Ok. But what if the sun is not shining? No problem. A solar water heater not only converts direct sunlight but also indirect sunlight into heat, so it works even when the sky is overcast. True,there will be less solar heat available during the winter, but a back-up heater will boost the water temperature. The result is 100% comfort at all times, with plenty of hot water for a fraction of the cost.
