The Grundfos COMFORT PM range for hot water recirculation, low noise permanent magnet motor allows the energy consumption of to be reduced to as little as 5-7W.
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
Minimise water waste
All Grundfos COMFORT pumps – with or without the AUTOADAPT function – combined with a return pipe deliver instantly hot water all over the house. This eliminates the expensive – and annoying – wait for the water to get warm and reduces the annual consumption of domestic water. The results are lower costs while still ensuring the comfort of instantly hot water.
All three Grundfos COMFORT PM pumps AUTOADAPT, COMFORT Digital Timer and the continuously running COMFORT pump are equally compact and designed to greatly facilitate .installation – even in confined spaces. Connect the plug and start pumping
The AUTOADAPT function has been developed for domestic hot-water systems with hot-water tanks as primary heating source.
In domestic hot-water systems with integrated temperature control functionality
for raising and lowering the temperature on the recirculation pipe, Grundfos
recommends using the fixed speed COMFORT models.
To get the full advantages of the COMFORT AUTO model with the AUTOADAPT feature, Grundfos recommends installing the pump in systems with hot-water storage tanks.
- Minimum energy consumption
- Minimise water waste
- Easy maintenance and replacement

Grundfos offers an efficiency analysis of your existing pump system, providing you with suggestions for increasing efficiency and thus for achieving cost savings over time.
Increase the efficiency of your existing system
Conducting an efficiency analysis of your existing pump system provides you with a basis for increasing efficiency and thus for achieving cost savings over time. An efficiency analysis results in suggestions for increasing efficiency and will show how this will save you money.
Grundfos offers the following levels of analysis for assessing the efficiency of your pump system:
- Installed base checks.
A basic evaluation is carried out purely on the basis of the data from the identification plate on the pump, comparing its performance with that offered by newer, more efficient technology and materials found in modern pumps.
- Pump efficiency quick check.
Pressure and the consumption of the pump in kWh are measured. Flow is estimated on the basis of available pump data and the results of the measurements.
Some of the resulting suggestions for improving efficiency might include a speed control upgrade, a motor upgrade, differently dimensioned pipes, the installation of a controller, or perhaps an agreement for routine service.
Complete pump audit
The efficiency analysis offered by Grundfos makes up the first step in our Pump Audit, a diagnostics tool that we use to check whether the pump system is operating at the optimal energy consumption to guarantee that your costs are kept to an absolute minimum – now and in the future. See "Replacement analysis" to find out more about the Grundfos Pump Audit.
Repair and maintenance
Grundfos Service can advise you on efficiency issues, offering suggestions for saving money in the long term.
Not all our products need spare parts. Our pumps are designed to provide low energy consumption and the highest possible performance throughout their lives. For some pumps, the greatest efficiency and reliability are achieved by replacing worn-out pumps rather than repairing them.
Naturally, you can always call Grundfos for repair and maintenance of pumps you have purchased from us. It is important to remember that an upgrade or even a replacement pump can be cheaper than repair in the long term.
Effective service – wherever you are
Grundfos Service is always close by. Working in collaboration with our local authorised service partners we offer worldwide service. Help from qualified pump professionals is never far away, whether you need immediate assistance or are interested in hearing about opportunities for making savings.
Grundfos Remote Management
Grundfos Remote Management is a cost-effective, secure and reliable way to monitor and manage pump installations from an Internet PC at a very low cost.
Connecting pumps and people
With a secure and reliable remote management system, you can monitor and manage your pump systems from an Internet PC at a very low cost.
Grundfos Remote Management is a cost-effective and straightforward system for monitoring and managing pump installations in commercial buildings and in water supply and wastewater systems. It reduces the need for onsite inspections, and in the event of an alarm or warning, the relevant people are notified directly.
The system offers a wider range of benefits and functions than mobile-phone-based monitoring. For those who do not require remote process automation, Grundfos Remote Management is the ideal solution for monitoring and remote control, rather than traditional SCADA (Supervisory Control and Data Acquisition) systems. Initial investment is minimal, and a fixed low fee covers data traffic, hosting costs and system support, including back-up of all data.
Efficient alarm management
The on-call schedule in this new telemetry system ensures that alarm messages from onsite controllers go directly to the relevant people. The system manager can log on from a PC anywhere and plan who is to receive alarm messages from each installation at any given time of the day. Managers can plan for years ahead, and can easily handle day-to-day exceptions to the schedule.
Optimise service and maintenance
Changes in pump performance can be tracked using trend graphs generated automatically by the system. This tracking can give an indication of any wear or damage in the installation, and service and maintenance can be planned accordingly.
The communication interface (the CIU271 modem) enables data transmission via GPRS/SMS from your Grundfos pumps and controllers. The built-in multi-purpose I/O board allows you to connect sensors and switches.
The purpose of CAPS is to provide a complete tool that contains both an extensive catalogue of Grundfos products and a sizing program to select the most suitable pump for your application.
There is also a comprehensive pump replacement selection function for central heating circulator pumps, hot water pumps and wastewater S pumps, and a function for producing professional quotations that include curves, drawings, quotation texts, wiring diagrams, etc.
Last but not least, the software contains the instruction and operating manuals for nearly all Grundfos pumps in multiple languages. Service drawings, exploded views and parts lists are available for all sewage products as well as several other pump types.
CAPS is available in two versions: WinCAPS, available on CD-ROM, and the online version WebCAPS, available at the Grundfos website. Additional features available in WebCAPS include CAD Drawings and Literature.
Not all our products need spare parts. Our pumps are designed to provide low energy consumption and the highest possible performance throughout their lives. For some pumps, the greatest efficiency and reliability are achieved by replacing worn-out pumps rather than repairing them. Our latest generations of products offer improved comfort, better functionality, and improved value for money.
