The primary application of a buffer tank is to reduce heat pump, chiller, or boiler short cycling. Hydronic buffer tanks
are used in systems operating below the design load condition, which is most of the time, or in systems having several
low BTU cooling or heating loads calling at different times. This can cause the heat pump or the boiler to short cycle,
resulting in reduced operating efficiency and shorter equipment life.
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.
