Carbon-neutral heat pump solutions for district heating
While district heating already has an environmental advantage over individual heating systems, there is a need to reduce its overall carbon footprint. The added attraction of setting the sector free from the price and supply volatility of the fossil fuel markets is leading utilities and decentralized energy suppliers towards large-scale heat pumps powered by renewable electricity. Heat pumps not only produce cost-efficient heat but also help integrate renewable energy into the grid.
MAN technology for district heating and cooling
We scale our heat pumps to the temperature and power needs of our customers. Large-scale MAN heat pumps can supply the heating and cooling needed for local residential and industrial or commercial needs. The heat sink temperature for warm water ranges
between 70 °C and 140 °C, suitable for heating water and making steam. The power output ranges from 10 to 90 MWth per heat pump unit. For hot water production, we offer solutions
with two different working principles: the transcritical compression cycle (TCC) and the vapor compression cycle (VCC). MAN electro-thermal energy storage (MAN ETES) heat pumps add
energy storage and management capability.
MAN transcritical compression cycle (TCC) heat pumps
MAN TCC heat pumps make good use of the special properties that CO2 offers as a refrigerant fluid – it works very efficiently at high and low temperatures as well as being non-flammable. Operating with an optimized transcritical compression cycle (TCC), our heat pumps have a perfect range for most district heating and cooling requirements: from 0°C to 150°C and up to 50 MW (170.61 MMBtu/h) of thermal heat and 30 MW of thermal cold (8,530 metric tons of refrigeration)
How industrial heat pumps can support the electricity grid with balancing power
Did you know that large-scale heat pumps can contribute to grid stability by providing balancing power? Our new white paper examines the technical factors, describes the balancing power markets, and demonstrates the benefits for heat pump operators. Download the white paper for more details about how ancillary services increase the economic viability of large heat pumps.
Rethink your heat supply: Heating, cooling, storage and energy management with MAN ETES
Get to know MAN´s ETES technology, an innovative heat pump system coupled with thermal storage that provides heat and cold in addition to electricity, and its wide range of applications. Our technology can be employed in various fields such as district heating and cooling or industrial processes.
MAN vapor compression cycle (VCC) heat pumps
When the district heating network supplies water or steam, we can provide vapor compression cycle (VCC) heat pumps that use ambient or waste heat sources. The heat pump cycle is driven by a well-proven radial geared compressor. For district heating systems based on superheated steam, we can also deliver an additional steam compressor to feed into the network. This can either be separate or integrated with the heat pump compressor. The systems ensure reliable production of hot water (up to 140 °C) and steam (up to 280 °C).

MAN Heat pumps for district heating
Heat pumps are one of the mainstays of our energy supply and are becoming increasingly relevant for a sustainable future.
We are pleased to invite you to our MAN ExpertTalk, which will focus on MAN Heat pumps solutions for district heating.
First, we will be looking at the development of the heat pump market in Europe and the USA and presenting our transcritical and vapor compression cycle technologies. We will also be looking at the potential for sector coupling, explaining our position on PFAS, outlining plans for butane and propane, and reporting on the Esbjerg and Aalborg projects.
We are looking forward to an exciting exchange with you in our live session.
Your host will be Raymond Decorvet.

Heat pumps in action: two case studies
The use of MAN heat pumps in two Danish cities demonstrates how renewable energy can be harnessed to heat homes and factory facilities.
MAN ETES heat pumps replace coal in Esbjerg
We have installed two MAN ETES heat pumps in the Danish port town of Esbjerg to replace its coal-fired heat and power plant. The pumps use energy from the local wind farms to multiply the heat of water from the sea. CO2 serves as an eco-friendly refrigerant – instead of being emitted as a greenhouse gas. The new heating system should save 100,000 metric tons of CO2 emissions per year.

Climate-neutral district heating in Aalborg with three MAN heat pumps
The Danish city of Aalborg is set to reduce CO2 emissions by 160,000 metric tons annually with the installation of three MAN heat pumps. With a total heat output of 132MW, the new seawater heatpump plant in Aalborg will be one of the largest of its kind in the world. Using renewable electricity produced by the utility plant operator Aalborg Forsyning, the heat pumps will raise the seawater’s temperature from a range of 1-15°C up to 98°C.
