Solar Plumbing

Many types of solar hot water systems are possible. I personally like the serpentine, closed loop system, with a multi-tank, non pressurized heat storage vault and double barrier heat exchange or even better the new improved MTD design. A multi media show the drain down system and more shows are available from the  Multi Media Page  

Since the drain back system is popular and easy to install I made a partial screen web based show available for FREE that illustrates the nature of this hydronic system. View & here the show by clicking this Drain Back graphic . 


Every Solar hot water system has it's own plumbing advantages and disadvantages.

Here are the basic solar hot water heating systems available today.
