The pump supports 10 automatic operating modes, ensuring efficient performance in both fixed and dynamic systems. With automatic night power reduction to 5 watts and integrated protection systems, it's a durable, cost-effective solution for larger heating circuits.

The BritTherm P5 32/8-180 is a robust circulator pump designed for demanding domestic HVAC systems. Whether installed in a boiler, HIU, or heat pump setup, this model provides outstanding performance and control. Its dual PWM modes (GT and ST) enable seamless integration with a wide range of low-voltage thermostats and controllers, including Siemens and Honeywell.

Equipped with 10 automatic operating modes, it adapts effortlessly to various system types. AUTO mode covers the majority of heating setups, while CP1 and CP2 maintain consistent performance for underfloor heating. PP1 and PP2 dynamically adjust to changes in flow rate, making it perfect for variable demand systems. Traditionalists will appreciate the inclusion of three fixed-speed settings for manual control.

Energy-saving functionality is built in, with an automatic night mode that reduces consumption to just 5 watts, maintaining comfort while cutting energy use. Thermal and electrical protection safeguards the pump from damage due to external faults, adding reliability and peace of mind.
