In a commercial heating system, energy-efficient pumps are only half the story. But with the right system design, you can truly reap the benefits and significantly reduce the energy bill.
Plan your heating system from the outside in
Solely relying on efficient pumps only gets you so far. But by taking the entire commercial heating system into consideration, you can move energy savings to the next level. Innovative controllers, integrated frequency converters and silent-running variable speed pumps all deliver the required system intelligence to maximise the efficiency of your commercial building heating system. By thinking about the whole system and not just the pumps, you can quickly increase comfort levels, future-proof your building and not least, save energy. We offer pump solutions and system know-how to help you design and build the most efficient commercial heating system around.
How to save up to 80% pump energy
Sligo University Hospital retrofitted its heating system with new boilers and intelligent pumps from Grundfos. With remote monitoring and control and built-in intelligence that adapts the pumps’ output to the actual heating system pressure, the hospital is saving up to 80% on energy on the new pumps. Watch the film and read more.
Whatever your system challenges, there are several ways intelligent controls can help. In our controls application guide, you can learn everything there is to know about how to install and commission our solutions to fully optimise your HVAC system. Find out how to:
- Reduce energy consumption
- Increase system performance
- Reduce manual monitoring
Easy installation and commissioning
See how to secure easy installation and commissioning in HVAC systems with the Grundfos TPE3. The TPE3 can easily be connected to any building management system, increases end-user comfort, is fully flexible, and adapts to load requirement in your building.
The all-purpose MAGNA3 for any HVAC system
Learn how to make installation and commissioning easy with the Grundfos MAGNA3 application wizard. Your benefits include:
- Simple installation and commissioning
- Reduced energy consumption
- Increased system performance
With rising demands for energy efficient heating solutions, a broad perspective is needed to fully understand how a building is heated and the impact of air-based vs. hydronic systems. Learn more about the advantages and disadvantages of primary, secondary and tertiary heating systems as well as varied pipe configurations and system balancing.
Dubai buildings unlock up to 80% pump energy savings with simple pump swaps
A Dubai building owner is saving 50-80% electricity from the pumps in its air-conditioning systems. With a retrofit, the customer got new, state-of-the-art pump equipment and is providing a better environment to residents. The project is in line with Dubai’s goal of saving 30% of its pump energy by retrofitting 30,000 buildings by 2030.
How does one read a pump curve of a heating pump?
The pump curve of a heating pump displays the feed rate on the x-axis and the delivery head on the y-axis. The pump curve shown in the graph is curved, dropping off from left to right.
Every possible duty point of the pump is shown on the pump curve where the dependencies are as follows: high feed rate = low delivery head; low feed rate = high delivery head.
In a heating system, a system curve emerges as a function of the system hydraulics. This curve intersects with the pump...
What is the heating system filling water requirement?
VDI Guideline 2035 Part 1 has been in effect since 2005, and VDI Guideline 2035 Part 2 has been in effect since 2009. These guidelines represent recognised rules of the technology. Ongoing technical advances as well as efficiency improvements and energy optimisation mean that modern heat generators and heating pumps are designed with lower tolerances than they were in the past. These technical advances have led to increased demands placed on the medium pumped in the system, as defined by ...
Why does the heating system not reach a sufficient temperature?
Possible cause of the fault
Automatic night set-back is active
The hydraulic conditions have changed. The pump must adapt to these.
When night set-back is activated
Switch on night set-back using Button 4 (for MAGNA, use Button 3).
In "AutoAdapt" mode
Possible cause of fault: The "AutoAdapt" function is unable to correctly adapt the heating system.
Why is the heating system making noise?
Possible cause of the fault
The flow rate is too high
This can be resolved by setting the pump to a setting other than "AutoAdapt"
Note the pump setting that appears on the display.
Then use Button 5 to switch the pump to "AutoAdapt". (for MAGNA, use Button 3)
If the supply of heat is sufficient at this point, leave it at this setting.
If the supply of heat is not sufficient, restore the previous setting...
