Heat transfer stations: District & local heat stations from ewers

Whether district heating or local heating: we build high-quality and sustainable heat transfer stations for capacities up to 10 megawatts and larger. They are suitable for private and commercial purposes, such as: Single and multi-family homes, residential complexes, offices, stores, administrations, industry, agriculture, hospitals, boiler or heating houses and much more.

Our local and district heating transfer stations work smoothly with different heating circuits and distributors. In addition, you can also get the stations with drinking water heating systems. The connection is direct or indirect, i.e. primary or secondary. We deliver each heat transfer station with precisely fitting insulation and high-quality gaskets.

Not only can we supply you with district heating and local heating stations – we also offer a wide range of accessories, such as storage technology in various sizes. At ewers, you get a comprehensive package for quick installation and convenient use of your heat transfer station.

Why a heat transfer station from ewers?

The local or district heat transfer stations from ewers are characterized by their high quality and sustainability. This is demonstrated by the fact that our heat transfer stations both operate ecologically and maintain a high level of performance over the long term.

The reason for the longevity of our heat transfer stations lies in their nature. Among other things, we assemble the local and district heat transfer stations from high-quality castings. These are made of gunmetal, a rustproof material. We also use rust-resistant nodular cast iron and durable gray cast iron. The high-quality materials help to ensure that you make a sustainable investment in your future with our heat transfer stations.

We use our materials as follows:

  • Gunmetal is used primarily & secondarily.
  • Spheroidal graphite cast iron is used primarily
  • Grey cast iron is used secondarily

Planning and construction from one source

Another reason for the high quality of our products is our vertical range of manufacture. We design and manufacture our heat transfer stations ourselves. The castings for our heat transfer stations are developed in-house – we have them produced regionally in Germany.

In production, we turn, mill, weld and assemble them ourselves – we also wire the stations ready to plug in. The advantage: You get a product whose individual parts are perfectly matched to each other. Our employees can also maintain and repair them more effectively. Since we do not need any special tools for maintenance, we can replace spare parts easily and without any problems.

Frequently Asked Questions (FAQ)

District heating generally refers to the supply of heat for heating buildings and providing hot water. The heat usually comes from combined heat and power plants, or cogeneration units. Almost any conceivable energy source can be used here.

The prerequisites and conditions for connection to the district heating network are stipulated in the utility’s TAB. Exceptions and/or additions to the currently valid standards are specified. The TAB must be complied with when executing a district heating connection.

The transfer station transfers the heat of the district heating water from the district heating network to the house installation. This transfer usually takes place via a heat exchanger in the heat transfer station.

The district heating transfer station is the link between the house connection pipe and the house control center. It is used to transfer the heat to the building control center in accordance with its intended use, e.g. with regard to pressure, temperature and volume flow.

The heating water from the heating network flows through the house system.

The heating water of the domestic system is separated from the heat network by a heat exchanger. In the case of indirect connection, one obtains a primary and a secondary circuit.

The part of the system through which the heating water of the district heating network flows is called the primary circuit.

The part of the system through which the heating water of the domestic system flows is called the secondary circuit.

A heat exchanger (often referred to as a heat exchanger) hydraulically separates the heating water of the district heating network from the heating water of the domestic system.
