The Taco Solar Pumping Station combines all the components needed for a closed loop solar water heating system, including a variable speed circulator, isolation valves, an air eliminator, flow meter, and safety components. The variable speed solar control continually adjusts the circulator speed to maximize solar collector output and improve system performance by 20% by preventing short cycling. The Solar Pumping Station simplifies installation with just 5 connections for the solar collectors, storage tank heat exchanger, and expansion tank.

Solar Pumping Station
The Taco Solar Pumping Station (SPS-PC-1) 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.
The solar control continually adjusts the speed of the circulator to maximize the output of the
collector, increasing the usable higher temperature water throughout the day while eliminating
short cycling and increasing system performance by 20%.
