Grundfos Important Facts System

To save your customers wasting time, money and water on a daily basis, they need to install a hot water recirculation system. In practice, this means that a plumbing system has to include one string for cold water (conventional) and another for hot water.
Installing a Grundfos circulation pump in the hot water string ensures that hot water is always available throughout the system. Turn on a hot tap anywhere in the house and the water will always be hot. No waiting. No waste.


The COMFORT pump with AUTOADAPT sets new standards for energy-efficient comfort in private homes. In the course of only a couple of weeks the intelligent pump learns the consumption pattern of the household and adapts to it. The stored data ensures that the pump runs only when required, cutting back on both water and power consumption – which in turn saves money. Energy savings of up to 85% can be achieved.

The COMFORT pump with AUTOADAPT is part of Grundfos’ popular COMFORT circulator range.

Instantly hot water has been the popular characteristic of Grundfos’ COMFORT pump. Now, we take the solution one step further with the introduction of the new COMFORT pump with AUTOADAPT.

Reliability is never compromised.

Should the consumption pattern change, e.g. during holidays, the COMFORT pump with auto adapt recognizes the standstill after 24 hours and automatically adapts to holiday mode.  On the return of the occupants, the intelligent pump will automatically resume the same consumption pattern as before the holiday. Consequently, the access to instantly hot water is never jeopardized.

Disinfection operation
Once every week, the system’s boiler significantly increases the water temperature. The increase is recognized by the pump sensor and hot water is circulated for 15 minutes for disinfection purposes. To further ensure that bacteria growth is efficiently prevented, the system is automatically flushed if the pump has been on standby for eight hours.
