Water contained in low cost, non-pressurized cylinders has proven to be the most practical and effective approach to the capture and storage of thermal energy for space and hot water heating.  Water stores 3 to 4 times as many BTU’s per lb. as rock or masonry.  It also releases this heat energy faster when you really need it. With over 35,000 units in use worldwide, Sun-Lite® Solar Storage Tubes are the most efficient and cost-effective way to store solar thermal energy and keep your greenhouse or sunspace cooler in the summer and warmer in the winter.
