At the AHR Expo, Las Vegas, NV, January 31, 2011 -Taco’s newest solar technology combines all the components needed for a closed-loop water heating system into a single, pre-engineered package. There are just five easy connections to make: two for the solar collector(s), two for the storage tank’s heat exchanger, and one for the expansion tank. The solar pumping station (SPS) includes isolation ball valves, air elimination, flow meter and a safety group.
The SPS is now available in three variations: with a standard Taco circulator; a variable speed controller built into the circulator; or a separate variable speed controller with a graphics based digital display. The display version features multilingual text, data storage with statistics and graphical analysis, and it monitors energy collected with simple heat metering.
The unit continually adjusts pump speed to maximize solar collector output, a feature that increases system performance by 20%. If a higher Delta-T is maintained through the collector, then higher source temperatures are achieved over longer periods of time regardless of weather conditions.
Taco’s new solar products work with any solar thermal application, whether drain-back, open loop, or closed loop. They offer user-definable output for heat dump, 1 or 2 storage tanks, storage tank supplement or booster pump. Also the all-in-one design means each Taco product is pre-engineered, pre-plumbed, pre-wired and easy to install.
