A Rated Compact Conservatory Pumpset. This unique product is the ideal solution for single zone underfloor heating systems. It effectively is a combined pump, blending valve and manifold. You can plumb 15mm copper flow pipework directly into it and then run your Underfloor heating pipe work from the blended flow produced by the pumpset unit. Often the pressure from the boiler pump is not sufficient to circulate the warm water from the boiler around the underfloor heating loops, so a circulation pump is essential to maintain pressure and flow in the pipework. The pump supplied on this unit is a Grundfos UPS2 25 – 60 pump. Also it has a thermostatic blending valve to keep the flow temperature consistent. Most underfloor heating systems run on approximately 50 degrees flow temperature, so the flow from the boiler (typically 70-80 degrees) will need blending down to this temperature. This is essential for the protection of floor finishes such as wood and laminate, which are sensitive and will react to excessive heat. The flow temperature is controlled simply by a dial on the blending valve, allowing you to select between 35 and 65 degrees.
