Reduce your water heating bills by installing a thermal water heating system from Alternate Energy Technology. This system is built with a 80 gallon storage tank and is paired with a 64 square foot solar collector. The water is heated while flowing through drainback reservoir while simultaneously the heating water flows through the drainback reservoir. The water and heating water never come in contact in this closed loop system. The system is designed with a drainback reservoir allowing it to be used in colder climates.
