The BritTherm P5 32/6-180 Circulator Pump is engineered for HVAC systems including boilers, heat pumps, and HIUs. Featuring a 6-metre head and 32mm connections, it offers reliable pressure and flow for domestic heating applications. Its two PWM control functions allow remote operation via low-voltage cables, compatible with popular thermostats such as Siemens and Honeywell. With 10 automatic modes and energy-saving features, it adapts seamlessly to various heating system demands.

The BritTherm P5 32/6-180 Circulator Pump is a high-performance pump designed to meet the needs of modern HVAC systems, including boiler circuits, heat pumps, and heat interface units (HIUs). Its robust 32mm pipe connections and 6-metre head make it suitable for systems requiring higher pressure and flow.

This pump features two unique PWM functions (GT and ST), allowing remote control through two low-voltage cables, making it compatible with a wide range of controllers and thermostats, including Siemens and Honeywell.

Users benefit from 10 automatic operation modes:

• AUTO mode enables quick, one-button activation for around 80% of heating systems.

• Two Constant Pressure Modes (CP1 and CP2) optimise performance in underfloor heating and systems with stable flow rates.

• Two Proportional Pressure Modes (PP1 and PP2) adapt to systems with dynamic flow changes.

• Three fixed speed options provide manual control over the entire power range.

The pump also includes an automatic night power reduction function, lowering energy use to just 5 watts without compromising heating performance. Electrical and thermal protection systems safeguard the pump from failures due to external conditions, enhancing durability and reliability.
