Q&A
Q: What is the Taco VT2218?
A: The Taco VT2218 is a high-efficiency ECM (Electronically Commutated Motor) circulator pump designed for hydronic heating and cooling systems.
Q: What applications is the VT2218 suitable for?
A: Ideal for closed-loop hydronic systems, including radiant heating, snowmelt systems, hydro-air fan coils, and zoning with zone valves. It can also be used in constant speed mode for zoning with circulators, indirect water heaters, or primary boiler loops.
Q: Is it compatible with water/glycol mixtures?
A: Yes, the VT2218 is acceptable for use with water or a maximum of 50% water/glycol solution.
Q: What additional components are included?
A: The VT2218 comes with sensors and an Integral Flow Check (IFC®) included.
Maintenance Tips
-
Ensure circulator matches your system’s specifications.
-
Adjust operating modes (Delta-T, constant speed, set point) to system needs.
-
Purge air from the system to prevent air binding and overheating.
-
Maintain proper system pressure within recommended range.
-
Check for unusual noises indicating wiring or valve issues.
-
Inspect regularly for wear, leaks, or damage.
