The Taco X – Pump Block (XPB) represents a breakthrough in the design, control and installation of heating systems. The patent
pending design combines a variable speed mixing control (VSMC), heat source circulator, system circulator, and heat exchanger into a
single unit. This combination delivers complete isolation between the heat creation source side of the system (boiler, water heater, etc.)
and the heat delivery side of the system (radiant tubing, glycol based snowmelt, baseboard, etc.). Extremely versatile, the
X – Pump Block can be set up to operate in outdoor reset, setpoint or delta T limiting mode.
