HF-22-BT-4 Heat-Flo 22 Gallon Stainless Steel Hydronic Buffer Tank With Four 1-1/4" NPT Connections

The primary application for the HF-22-BT is to reduce low-mass modulating, condensing boiler short cycling. The high and low left side connections are used for boiler supply and return. The top connection is used to supply the distribution system and the low right connection is the return from the distribution system. If the top connection is piped to the line supplying the air purger and vent, the tank will be self-venting.
