District heating systems distribute heat to residential, commercial and industrial buildings. Grundfos offers a variety of efficient and reliable pumps that contribute to making district heating one of the most popular heating systems in the world.
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.
District heating has the potential to reduce CO2 emissions and heat losses while increasing consumer comfort. Discover how Grundfos iSOLUTIONS can help your district heating systems run with lower temperatures and optimal efficiency with the use of intelligent solutions.

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 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...
