New for 2019, Taco Comfort Solutions’ 0018e high-efficiency, Bluetooth-enabled circulator brings a new level of control to residential and light commercial hydronic systems, the company notes. The ECM-powered 0018e features Bluetooth communication to a mobile app, providing real-time control, diagnostics and reporting, such as installation history, power consumption, performance and runtime. Installers can select between multiple constant-speed, proportional-pressure and constant-pressure modes, as well as activeADAPT. The BIO Barrier protects the pump from system contaminants, especially black-iron oxide that otherwise tends to collect around strong ECM magnets. SureStart automatically unblocks a locked rotor and purges air from the circulator. The 0018e features 18 feet of maximum head with a maximum flow of 16 gpm. It’s also double-insulated, which eliminates the need for a ground wire.
