Upgrade your plumbing system with the BritTherm B3 Bronze Circulator Pump—a state-of-the-art circulator designed for superior performance, energy efficiency, and peace of mind. This intelligent, automatic pump is the ideal solution for the circulation and recirculation of both domestic **hot and cold potable (drinking) water**, thanks to its high-quality bronze casing. 

Smart Performance and Unrivalled Efficiency

The B3 series is engineered to meet the most stringent Ecodesign (ErP) regulations, boasting an Energy Efficiency Index (EEI) as low as 0.16. This makes it one of the most cost-effective and environmentally friendly pumps on the market. Its cutting-edge design features **9 built-in intelligent operating modes** that automatically adjust to the specific needs of your water system for optimum comfort and minimal power consumption:

  • AUTO Mode: Automatically determines the optimal operating range, ensuring peak performance and efficiency.
  • 3 Fixed Speeds: Provides traditional manual control (often referred to as 'Old School' modes) for simple power adjustment.
  • 2 Constant Pressure Modes (CP1 & CP2): Maintains a steady system pressure regardless of changes in flow rate.
  • 2 Proportional Pressure Modes (PP1 & PP2): Dynamically adjusts the pump's operation in proportion to flow rate changes, ensuring efficiency under varying demands.
  • Night Operating Mode: Drastically reduces energy consumption to as low as 5 watts during low-demand periods.

Key Features and Benefits

The BritTherm B3 is built to last and engineered for reliability:

  • Bronze Construction: The durable bronze body makes the pump perfectly suited for **potable water** (domestic hot water) applications.
  • WRAS Approved: All components in contact with drinking water comply with strict WRAS standards, guaranteeing safety and quality.
  • Exceptional Guarantee: Benefit from a leading **6-year manufacturer's guarantee** (registration required) on all B3 models.
  • Integrated Safety: Includes built-in electrical and thermal protection systems to guard against pump damage and ensure a long working life.
  • Quiet Operation: Designed for a low noise level, providing minimal disruption in domestic and light commercial environments.
  • Max System Pressure: Robustly handles up to 10 bar.
