BritTherm Automatic Сirculator Pump P5 Series P5 25/4-130 (661995702)

The BritTherm P5 25/4-130 Circulator Pump is the ideal choice for smaller heating systems or applications requiring lower head pressure. With a compact 130mm body and 25mm connections, it’s perfect for tight installations such as HIUs, combi boilers, or zoned circuits. Despite its modest 4-metre head, it offers all the intelligent features of the P5 Series: 10 operating modes, including AUTO, constant and proportional pressure settings, as well as three fixed speeds. Dual PWM control and built-in night mode ensure full smart system compatibility and energy efficiency.

Compact yet powerful, the BritTherm P5 25/4-130 is engineered for domestic heating systems that demand space efficiency without sacrificing smart control. With a 4-metre head height and 25mm connection, it’s ideal for applications such as HIUs, hot water recirculation, and small heating loops.

The pump is equipped with dual PWM inputs (GT and ST), allowing remote control integration with thermostats and controllers including Siemens, Honeywell, and others. It delivers 10 different operation modes to suit a wide variety of heating scenarios—from constant or proportional pressure for underfloor heating to fixed-speed options for traditional setups.

Its AUTO mode simplifies installation, automatically selecting the best settings for 80% of systems. The Automatic Night Power Reduction Function reduces electricity use to just 5 watts when heating is not required, contributing to lower energy bills.

Electrical and thermal protection ensures safety and reliability, making the P5 25/4-130 a dependable solution for modern heating systems.
