The BritTherm P3 25/4-180 circulator pump is designed to deliver exceptional heating system performance with nine automatic operation modes. Its compact design and accessible control panel make installation simple, even in confined spaces, while its advanced modes ensure energy-efficient and reliable operation for any domestic heating system.

The BritTherm Automatic Circulator Pump P3 Series P3 25/4-180 offers advanced functionality tailored to domestic heating needs. With nine built-in automatic modes, this pump adjusts intelligently to the system’s requirements, balancing comfort and energy savings.

The pump’s AUTO mode activates with a single button press, optimising operation for the majority of heating systems. It features two constant pressure modes (CP1 and CP2), which maintain steady pressure regardless of flow changes, and two proportional pressure modes (PP1 and PP2), which respond dynamically to pressure fluctuations in proportion to flow rate.

For manual control, three fixed speeds can be selected, allowing full range use of the pump’s power. The automatic night power reduction function cuts energy consumption to just 5 watts during off-peak periods, ensuring efficient operation without compromising heating quality.

Electrical and thermal protection systems safeguard the pump from damage caused by external factors, enhancing its durability and reliability.
