{"product_id":"esbe-single-room-ufh-mixing-pump-pack-with-grundfos-upm3-flex","title":"ESBE Single Room UFH Mixing Pump Pack with Grundfos UPM3 Flex","description":"\u003cp\u003eA single room underfloor heating mixing pump pack with a Swedish-made ESBE valve and a Grundfos UPM3 Flex 25-70 130 pump. Use it to add wet UFH to one room, such as an extension, kitchen or conservatory, straight off a radiator or boiler circuit. The PWM-ready pump suits jobs where the boiler will control pump speed. The ESBE valve has a built-in bypass and holds a steady 35–60°C to the floor loop, and the pack mounts on its own wall back plate.\u003c\/p\u003e\u003ch3\u003eWhy installers use it\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eGrundfos UPM3 Flex:\u003c\/b\u003e up to 7m head and PWM speed control from the boiler or heat pump.
