Intelligent, reliable and efficient district heating systems
District heating systems distribute mass amounts of heat over potentially large areas. And in order to keep the customers happy, three factors are important: reliability, efficiency and intelligence. Grundfos supplies a wide portfolio of pumps to power plants, in boiler houses and in the distribution lines, all combined to ensure that heat is distributed optimally – satisfying all heating demands throughout the district heating network.
Keeping a district heating system running reliably requires attention to detail. Grundfos can help with that. Pressure, flow and temperature are the three main parameters to consider, but water purity and pH-value also play a part in deciding the level of wear and tear in your pipes. However, these parameters can be controlled with a flow filter system and an effective water treatment system, both of which feature Grundfos pumps.

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.
Remedy
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...
