Open system vs closed? Barrier vs non-barrier tubing? Boiler vs water heater?
The debate ends here. The patent pending X-Pump Block combines a variable speed mixing control, heat source
circulator, system circulator, and heat exchanger into a single unit. This combination delivers complete isolation
between the heat generation side of the system (boiler, water heater, etc.) and the heat delivery side of the system
(radiant tubing, glycol based snowmelt, baseboard, etc.). Just four pipe connections and your installation is complete.

Application
The X-Pump Block (XPB) is a complete mixing system with an attached brazed plate, counterflow
style heat exchanger for system isolation. Integral to the unit is a variable speed heat source circulator,
constant speed system circulator and the electronics to drive it all. The XPB can be set up to operate
as an outdoor reset control, a setpoint control or a delta T limiting control. This unparalleled flexibility
within a single unit creates a pumping and control package that can be used in systems combining any
style heat source (boiler, water heater, etc.) with any style heat delivery method or system condition
(radiant tubing, glycol based snowmelt, open system, etc.). With just 4 piping connections needed, the
XPB greatly reduces the time and space required for installation.
The features of the X-Pump Block makes it easy and cost effective to include a hydronic based radiant
floor warming system in any kitchen and bath remodel project, especially in homes which have an air based
heating system. The XPB also makes the perfect companion for basement “radiant ready” packages, jobs
where space is at a premium, and small snowmelt areas such as handicap accessible building entrances.
Operation
Hot water from the heat source, such as a boiler, enters the X-Pump Block’s integral heat exchanger
at port (A1) and exists at (A2). The variable speed circulator controls the speed of the water flowing
through the A side of the heat exchanger to satisfy the heat transfer requirements between the A side
of the heat exchanger and the B (system) side. The heat exchanger is a counterflow style, so system
water enters at port (B1) and exits at port (B2). A constant speed
circulator moves the water around the B (system) side. In
certain applications, such as snowmelt, the system pump motor
can be switched with the variable speed motor in order to
protect the heat exchanger from freezing up by ensuring
constant flow on the heat source side.
Sizing and Piping
The X-Pump Block can handle transfer loads of up to approximately
50,000 BTU. Your current method of piping virtually remains the
same; yet complete system isolation is achieved. The only addition
needs to be a separate expansion tank and relief valve on the system
side. 1 outdoor sensor, 2 strap-on sensors and a line cord are
included for fast plug n’ play wiring.
