Non-Mixing Pumpset with Wilo PARA

Non-Mixing Pumpset is the ideal solution for low-temperature underfloor heating (UFH) in heat pump systems. This compact, prefabricated non-thermostatic kit includes the high-efficiency Wilo PARA A-rated circulator pump. It connects your circulating pump, flow, and return lines directly to the UFH manifold—no blending valve required.

Moreover, the non-mixing pumpset suits low water temperatures (typically 35–55°C). Therefore, it simplifies installations for air source heat pumps (ASHP), ground source heat pumps (GSHP), solar-assisted systems, or low-temp boilers in homes, bathrooms, extensions, conservatories, or single-zone setups.

The pack includes a four-way connector, connecting elbow, and flow tee piece. Furthermore, it features a handy ½” FBSP tapping for temperature/pressure gauges, sensors, or overheat thermostats.

Key Features

• Non-thermostatic design. Thus, optimised for heat pump and low-temp UFH—no mixing valve needed.
• Flexible setup. Choose left-hand or right-hand connection.
• Versatile pipe entry. Side or bottom options for added ease.
• Angled pump flange. As a result, flow and return pipes stay level.
• Connections. ¾” inlets to 1” outlet manifold; pump uses standard 1.5″ BSP at 130mm centres.
• Durable materials. Nickel-plated brass body/connectors with EPDM seals.
• Robust specs. Handles up to 90°C, 6 bar pressure, 32 lpm flow (pack level).
• Wilo PARA pump. High-efficiency A-rated, glandless circulation, low power consumption (e.g., 3–43W typical), silent operation, EEI ≤ 0.21, multiple control modes (constant/ variable pressure, constant speed).
• Pre-assembled & compact. Bolts straight to manifolds—no extra brackets or drilling.

Benefits

First, it cuts installation time dramatically. Pre-fabricated kit and pump connect in minutes.

Second, it saves labour costs. No separate fittings, valves, or custom pipework required.

Third, flexibility is excellent. Fits tight spaces, retrofits, new builds, or heat pump upgrades.

Moreover, it’s perfect for renewables. Pairs seamlessly with ASHP/GSHP/solar—safe, efficient, no overheating risks.

Additionally, the ½” tapping boosts safety. Add overheat protection or monitoring easily.

Finally, the Wilo PARA ensures top performance. Significant energy savings, reliable circulation for single or multi-loop manifolds, low-noise operation.

This UFH Heat Pump System Control Pack delivers a fast, flexible, energy-efficient non-mixing solution for heat pump underfloor heating. Reliable, pro/DIY-friendly, and optimised for modern low-temperature renewable systems.
