Flat stations - EvoFlat 4.0

The modern replacement for traditional centralized heating and domestic hot water solutions

Flat stations are decentralized heating systems installed in flats and apartments to provide residents comfortable heating and on-demand domestic hot water with the highest energy efficiency. The stations incorporate a compact plate heat exchanger, which delivers instantaneous hot water on demand and a differential pressure control valve to control the heating flow to the tenants’ radiators and underfloor heating.
The modular concept allows to order the station exactly as needed; nothing more, nothing less

Efficient Flat Stations for Direct Heating and Domestic Hot Water

Our flat stations offer seamless integration for direct heating with or without mixing loop and domestic hot water systems. With a direct flow from the network into the building, flat stations ensure swift and efficient operation. Underfloor heating variant comes specialized mixing loop that grants you precise control over the supply temperature for the apartment.

Direct substations are the ideal choice for networks operating at maximum PN10 or PN6 levels.


Efficient distribution systems - floor heating for flat stations

Our prefabricated underfloor distribution units cater to both floor heating and cooling applications. These versatile systems can be installed separately or directly connected to the Danfoss flat station range, in combination with a boiler or as an extension of the existing heating system. In addition, we offer recess boxes with mounting rails for seamless installation experience.

Experience a new level of efficiency and flexibility in floor heating distribution with our advanced solutions.

Features and benefits of flat stations

Cost-effective solution ideal for new installations, refurbishment and renovation projects offering low service and maintenance cost

Quick and easy installation.

Less space used, can be seamlessly integrated into walls, stairwells, or shafts

Precise energy metering and consumption monitoring

EvoFlat 4.0 - Better | Lighter | Easier

Completely new, industrial & modular, design to help you win project tenders. The modern replacement for traditional centralized heating and domestic hot water solutions.

EvoFlat 4.0 is the cost-effective choice for new build as well as renovation and refurbishment projects, thanks to its ease of installation in existing buildings. EvoFlat 4.0 stations are designed to align with diverse project needs. With the flexibility to connect to any available energy source, your investment remains secure, unaffected by the unpredictabilities of the future.

Within EvoFlat 4.0 flat stations lies a new innovative heat exchanger Danfoss XB05, designed with a revolutionary dimple pattern. It is complemented by a new TPC-M proportional controller that ensures instant domestic hot water. Additionally, two separate differential pressure controllers for DHW and heating guarantee a consistent heating experience.

Redefining Heat Pump Excellence with Evoflat 4.0

In the world of heating and cooling technology, the Evoflat 4.0 stands out as the perfect choice for heat pump systems.

Engineered with innovation and precision, this advanced flat station is designed to elevate the performance of heat pumps while optimizing efficiency and comfort in your building.

  • With enhanced insulation, the Evoflat 4.0 minimizes heat loss, ensuring that the energy generated by your heat pump is directed precisely
    where it's needed and optimizes chilled water distribution.
  • Boasting a remarkable combination of high capacity, high flow, and smaller dimensions, the XB05 heat exchanger redefines what's possible.
    With its innovative dimple design, heat transfer is taken to new heights, resulting in a lower temperature difference (dT) and maximizing the
    effectiveness of your heat pump system. This groundbreaking innovation is currently unmatched in the market.
  • Designed for heat pumps, the 4-pipe variant features separated risers for both heating and domestic hot water. This separation ensures optimal
    performance and distribution, allowing your heat pump to operate at its peak efficiency while delivering comfortable hot water whenever needed.
  • Finally, the advanced electronic controller guarantees quick responses to changing demands, precise supply temperature, and optimal
    return temperature control.


Embrace the future of heating and cooling technology by choosing the EvoFlat 4.0.
