Description for Taco SPS-PC-3

The variable speed circulator in the Solar Pumping Station continuously optimizes the flow through the collector to achieve maximum energy gain. For example, there is no benefit of pulling 80° water out of the collector when you are trying to maintain 120° in a tank. If a proper Delta-T is maintained through the collector then higher source temperatures can be achieved over longer periods of time, no matter the weather conditions.

The Taco Solar Pumping Station (SPS-PC-3) combines all the features needed for a closed loop solar water heating system. Just 5 easy connections to make: 2 for the solar collector(s), 2 for the storage tank's heat exchanger and 1 for the expansion tank. The Solar Pumping Station includes a circulator with an integral variable speed solar control, isolation ball valves, air elimination, flow meter and safety group.

    • Q:

      My storage tank is in the basement and my solar water collectors are on the roof. This will be a closed loop system. Will this unit have enough to pump that far? The specs say 15 feet.

        Closed loop systems have a static head of 0 and generally only have to overcome the friction head of the system. As such head pressures in closed loop systems are generally lower.
