Bastion A-Rated Single-Room Underfloor Heating Pump and Mixing Pack – 3kW, 7.5m Head Circulator

Efficient, Comfortable Heating for Individual Rooms

Enhance the comfort of smaller areas with the Bastion single-room underfloor heating pump and mixing pack, featuring an energy-efficient A-rated circulator with a maximum head of 7.5 metres. Designed for applications such as bathrooms, conservatories, home extensions and other individual heating zones, this compact assembly provides a convenient solution for extending water-based underfloor heating to areas of up to 20m², subject to system design and heat demand.

The unit connects to a compatible existing boiler or central heating circuit, helping simplify installation and minimise alterations to the property's heating infrastructure.

The integrated Bastion circulator combines efficient water circulation with low electrical consumption, operating within a stated input power range of 5–39W. A built-in thermostatic mixing valve blends and regulates the water supplied to the underfloor heating circuit, helping maintain an appropriate operating temperature and promote consistent heat distribution.

Key Features and Benefits

• Bastion A-Rated Circulator Pump: Features a canned-motor design for efficient circulation, reduced operating noise and dependable performance, with electrical consumption ranging from 5W to 39W.

• 7.5-Metre Maximum Pump Head: Provides additional circulation capability for suitable domestic heating installations. Actual performance depends on the required flow rate and the hydraulic resistance of the system.

• Multiple Operating Modes: Supports Auto Adaptation, proportional pressure, constant pressure and constant-speed operation. PWM signal compatibility enables integration with suitable external control systems.

• 3kW Heating Capacity: Designed for small underfloor heating zones, providing effective warmth when correctly matched to the room's heat loss and system requirements.

• Flexible Floor-Area Coverage: Suitable for areas of up to 20m² with 200mm pipe centres or 15m² with 150mm pipe centres, depending on insulation, floor construction, heat demand and installation design.

• Integrated Thermostatic Mixing Valve: Blends primary heating water with cooler return water to regulate the underfloor circuit's supply temperature. The stated temperature control accuracy is ±2°C, subject to the valve's operating conditions and specifications.

• Broad Heat-Source Compatibility: Suitable for appropriately designed systems supplied by gas or oil boilers, compatible wood-burning heating systems, solar thermal installations, air-source heat pumps, ground-source heat pumps and other suitable renewable heat sources.

• Convenient Installation: The compact assembly is designed to connect directly to compatible pipework without requiring separate mounting brackets in suitable installations. Supplied accessories include a pre-connected three-core power cable and 25mm gaskets.

• Energy-Conscious Operation: Efficient pump technology and individual-zone heating control can help reduce unnecessary energy consumption while providing comfortable, draught-free warmth.
