XPB-1 X-Pump Block, 2 @ 1/25 HP, 3/4" FNPT Connection

The Taco XPB-1 is a complete mixing system that puts an end to the debate of using an open system vs. closed, utilizing barrier vs. non-barrier tubing, or boiler vs. water heater. This model combines a variable speed mixing control, heat source circulator, system circulator and heat exchanger all into a single unit. Through this innovative combination, the XPB-1 is able to create complete isolation between the heat generation side of the system (boiler, water, heater, etc) and the heat delivery side of the system (radiant tubing, baseboards, etc.). With such unheard of flexibility, you can combine any style heat source with any style heat delivery method. It requires only 4 piping connections, reducing the time and space needed for installation. The XPB-1 is ideal for hydronic based radiant floor warming systems, basement radiant heating, or projects where space is a premium.
