BritTherm Automatic Сirculator Pump P5 Series P5 25/8-130 (661995718)

The BritTherm P5 25/8-130 Circulator Pump is expertly engineered for HVAC systems, including boilers, heat pumps, and heat interface units (HIUs). Offering an 8-metre head and a compact 130mm body length, this pump includes two PWM control functions (GT and ST) for seamless integration with popular controllers such as Siemens and Honeywell. With 10 automatic operating modes, it delivers versatile, energy-efficient performance for a broad range of domestic heating applications.

The BritTherm P5 25/8-130 Circulator Pump provides reliable and flexible heating system circulation with an 8-metre head, ideal for moderately high-pressure needs in boilers, heat pumps, and HIUs. Its 130mm length design fits neatly into many installation environments while maintaining robust performance.

This pump incorporates two unique PWM functions (GT and ST), enabling remote operation via two low-voltage cables compatible with a wide variety of controllers and thermostats, including Siemens and Honeywell models.

With 10 automatic modes, including the simple AUTO mode for quick commissioning across 80% of heating systems, the pump adapts easily to different system demands. It features two constant pressure modes tailored for underfloor heating or stable flow systems and two proportional pressure modes for systems with variable flow rates. Additionally, three fixed speed modes offer manual control options for more traditional setups.

An energy-saving night mode reduces power consumption to just 5 watts without sacrificing heating performance. Electrical and thermal protection features guard the pump against damage caused by external faults, ensuring long-lasting, reliable operation.
