Grundfos Comfort PM High Efficiency Domestic Hot Water Circulator Pump 240v with 1.5m Cable

The Grundfos Comfort B PM and BX PM pumps are designed for recirculation of domestic hot water in single-family and two-family houses securing hot water instantly to all faucets. The pumps have a corrosion-resistant pump housing suitable for drinking water and are powered by a single-phase, high-efficiency ECM with permanent-magnet rotor. COMFORT B PM and BX PM meet homeowner requirements for continuous operation. COMFORT BX PM has a built-in isolating valve and a non-return valve (fitting). This ensures that maintenance can be carried out without draining the system. The non-return valve also prevents reversed flow during operation. designed for:

  • domestic hot-water systems in single and two family houses
  • small heating systems
  • cooling and air-conditioning systems

The Grundfos COMFORT PM range sets new standards for energy-efficient hot water recirculation in domestic homes. Thanks to a low noise permanent magnet motor, energy consumption is reduced to as little as 5 to 8 Watts, while the superior AUTOADAPT function found on the BA PM model, ensures that the pump runs only when required, which minimises both heat and power waste. The result is maximum comfort with a minimum of water, heat and electricity consumption.

The pump is suitable for open and closed systems however, it must be installed indoors and should only be fitted into pressurised hot water circulation systems.
