Grundfos Single Circuit Pump & Mixing Valve Unit
Description
The Single Zone Temperature Controller and Pump Assembly is a compact, high-performance temperature control unit designed to precisely regulate the water temperature and circulation in underfloor heating systems. Intended to operate as an extension to an existing radiator circuit, it manages the flow temperature supplied to an underfloor heating loop with heat output up to 3 kW.
This unit features an automatic thermostatic mixing valve that blends water to the required temperature, ensuring consistent and accurate control within +/- 2°C despite fluctuating boiler flow and return temperatures. It is suitable for multiple heat sources including oil and gas boilers, wood burning stoves, solar thermal collectors, air and ground source heat pumps, and pellet burners.
Its lightweight and compact design allows direct connection to pipework without the need for additional brackets or mounting supports, simplifying installation.
