Heating Engineering

During the World Climate Conference, the German government pledged itself to have reduced carbon dioxide emissions by 25 % in the year 2005 compared to 1990. Over 30 % of energy in Germany is required for the heating of buildings, and as this type of energy is almost exclusively generated by the burning of fossil fuels, it is one of the most important areas in which the greenhouse effect can be reduced.


By using new boiler and burner technologies it is possible to achieve a low-emission combustion combined with a high degree of efficiency. German companies are amongst the leaders in the development and production of energy-efficient burners and boilers, whereby condensing boilers, which are fired with fuel oil or natural gas, are the most efficient.
Carbon dioxide is produced whenever carbonaceous energy sources are burnt during energy conversion. The amount of carbon dioxide varies, however, depending on the primary energy source. The amount of climate gas given off by natural gas is only half that given off by brown coal per kWh generated. And the popular heating oil is also less beneficial than natural gas in this respect. For this reason, natural gas is the preferred energy source today, and its use is rewarded by tax privileges.
Fossil energy sources are being used less and less for the heating of buildings. Condensing boilers which burn wood are gaining more and more popularity, in part thanks to state subsidies. For the private sector, a suitable material which helps reduce CO2 emissions is the wood pellet.

Project-IconCentral heating installation fired with wood chips
An enterprise of the power industry established a central heating installation fired with wood chips in a development area. In this way the development area is supplied to eighty per cent with heat from the renewable energy source wood. Thus, not only CO2 emissions were avoided, but also dust emissions reduced. To this end a waste gas condensation plant was established in the heating installation. Expand…

Project-IconData-based heating water monitoring system
The project developed a data-based tool for monitoring the state of heating water. The software module can identify harmful physical and chemical processes at an early stage and can thus prevent corrosion and a decrease in heat transfer. Expand…

PDF-IconDevelopment of a heat storage oven heated with solid fuels
The objective of the support project is to develop a storage heater using solid fuel, which is characterized by the possibility of controlled heat storage and heat emission. The firebox heated with wood is enclosed with a solid material mineral storage. Storage is charged directly via the two walls of the firebox or via a heat exchanger installed in the waste gas flow of the firebox. The process of storing and emitting heat is controlled depending on the temperature. This development is to make it possible to store the short-term high heat released when burning small pieces of wood for later use in living quarters (detail information in German).

PDF-IconDevelopment of products with plastic capillary tube mats for environmentally-careful area heating and cooling
The project goal of the „Clina Heating and Cooling Elements GmbH" is to open up further application types for plastic capillary tube mats from polypropylene within the field of heating and cooling of buildings. By means of this technology regenerative energy sources can be increasingly used for the air conditioning of buildings. The project is promoted with federal funds by the agency responsible for the project Jülich PTJ.

PDF-IconEmergency District Heating in Choibalsan, Mongolia
The Energy Authority of Mongolia has initiated a project which aims to contribute both to the habitability of the town of Choibalsan and to safeguarding economic development opportunities in Eastern Mongolia by maintaining the local heat and power supply. A refurbishment of individual turbines and boilers is intended to improve both energy reliability and the efficiency of the power plant. The project is being subsidised with KfW (Reconstruction Loan Corporation) funds.

Link-IconHeating and cooling buildings with SolarEis
A SolarEis storage system in the town of Constance on the edge of Lake Constance supplies a hotel with heat via a gas-absorption heat pump in winter, at the same time building up a stock of ice with which to cool the building in the summer. This combination uses significantly less primary energy than a conventional heating and cooling system.

In the context of a project promoted by the Federal Ministry of Economic Affairs and Employment a system was developed for the single room temperature control and energy cost distribution for industrially established housebuilding. Project aim was the demand-oriented control of heating and ventilation systems. It could be shown that an improved thermic protection entails a decrease of power demand and costs.

Link-IconMicro gas turbine heats housing estate
In the context of the Prize of the German Gas Economy 2002 the project “Housing Estate with Micro Gas Turbine” was awarded in the category “Prize for Rational and Environmentally-careful Natural Gas Use”. The project aim was to supply a housing estate with local heat. A micro gas turbine based on cogeneration is used. With the operation of the turbine only very small quantities of pollutants are set free, which are far below the regulations of the TA Air (German technical directive).
