Pumps for District Heating
With decades of district heating experience from Denmark and other northern markets, DESMI delivers energy-efficient pump solutions for both heat production and the transmission and distribution network.
District heating distributes hot water from a central energy source - such as CHP plants, waste-to-energy, industrial surplus heat, or renewables - through a network to residential and commercial buildings, before returning the cooled water for re-heating. The result is a flexible, scalable way to supply heat efficiently while supporting the transition to lower-carbon energy sources.
Because heat is the world’s largest energy end-use - around half of global final energy consumption - improving heat efficiency is one of the strongest levers for cutting emissions at scale.
