Pump Sets & Mixing Packs

Underfloor heating pump sets are an essential component in a wet underfloor heating system, responsible for circulating warm water through the system’s network of pipes laid beneath the floor. These pump sets ensure that heated water is efficiently distributed to provide consistent and uniform heating across the entire floor surface. Here’s an overview of what comprises an underfloor heating pump set and its functions:

Components of Underfloor Heating Pump Sets

1. Circulation Pump: The core component, usually a low-energy, high-efficiency pump that moves heated water from the boiler or heat source through the manifold and into the underfloor pipes.
2. Mixing Valve: This device adjusts the temperature of the water being circulated by mixing hot water from the boiler with cooler water returning from the floor circuits. This is important for maintaining the optimal floor surface temperature, which is typically lower than that used in standard radiators.
3. Flow Meters and Gauges: These monitor and control the rate at which water flows through each circuit, ensuring even distribution and efficient operation.
4. Isolation Valves: These valves allow for the isolation of the pump set from the rest of the heating system for maintenance or troubleshooting without needing to shut down the entire system.
5. Thermal Insulation: To enhance efficiency, the pump set and associated pipework are often insulated to prevent heat loss.
