Taco Comfort Solutions says its Taco 0015e3 is the only three-setting, ECM-powered circulator on the market. With three settings, the 0015e3 replaces all three-speed hydronic circulators in its class. Its variable speed, high-efficiency ECM motor also uses up to 85% less electricity, according to officials.

The company also says the circulator is ideal for hydronic systems zoned with circulators or zone valves, and provides three maximum-feet-of-head pressure settings to match system requirements — Low (5 ft), Medium (10 ft), or High (18 ft), with a maximum flow of 16 gpm.  

Other features include Taco’s BIO Barrier® to protect the pump from system contaminants, especially black iron oxide that otherwise tends to collect around strong ECM magnets. Also, SureStart™, which automatically unblocks a locked rotor and purges air from the circulator. The 0015e3 is double insulated, which eliminates the need for a ground wire.
Due to its energy-saving ECM design, the company said the circulator qualifies for most state, regional, and utility efficiency incentive programs. An integral flow check is included, and both two-bolt or two-way flange models are available.
