Combined with the intelligent AUTOADAPT function this sets new standards for
energy-efficient hot water recirculation in private homes.
Thanks to the new Grundfos COMFORT range now features three variants for hot water recirculation. All three Grundfos COMFORT pump with AUTOADAPT, Digital Timer and the fixed speed COMFORT pump can significantly reduce the power consumption. In fact, the electricity costs of operating in AUTOADAPT mode requires a mere 1-2 €* per year. Compared to conventional pumps that run continuously this equals a cost reduction of up to 96 %. Moreover, heat energy savings amount to as much as 48 %.
The principle of the AUTOADAPT function is really very simple.
In the course of only a couple of weeks the COMFORT pump learns the hot water consumption pattern of the household and adapts to it. The stored data ensures that the pump runs only when required – which significantly cuts back on both water and power waste. Should the consumption pattern change, e.g. during holidays, the COMFORT pump will 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
