Heating systems

To resolve the modernisation backlog in the heating market, we need the entire range of technology available. What is appropriate depends on the individual case – on the output required, the available fuel types and finally also on the individual requirements of the operator.

Oil and gas – high savings potential and a "green outlook"

Around 65 percent of the around 20 million heating systems in Germany are operated with gas, and 30 percent with oil. This means fossil fuels will continue to play an important role for a long time. Limited reach and the CO2 emissions associated with the oil and gas combustion call for not just more economical use of these natural resources, but also a "green outlook" in the form of higher biogenic ratios. With its high savings potential and low total investment, condensing technology is an economical solution. Through the use of an advanced, efficient oil or gas boiler, consumption can be reduced by up to 30 percent compared with an outdated heating system.

Particularly efficient – combined heat and power generation

Combined heat and power (CHP) represents efficiency technology with considerable potential, as it utilises the heat created during power generation for practical purposes. Compared with conventional, separate generation of power and heat (electricity from a central power station, heat from the heating centre or boiler room), CHP systems powered by natural gas reduce the primary energy consumption by around a third, and CO2 emissions by more than 50 percent.

An important prerequisite for economical operation of CHP systems to keep the system running for as long as possible. For this reason, CHP units have until now been largely used in buildings with high year-round power and heat demand, e.g. in hospitals, or commercial or industrial operations.

Systems based on fuel cell technology are ideal for use in new build detached or two-family houses as well as in modernised existing buildings with low heat demand. When modernising detached and two-family houses with higher heat demand, micro CHP units work particularly economically using a Stirling engine.

Biomass: CO2-neutral, convenient heating

With a share of 70 percent, biomass accounts for the largest proportion of renewables – for good reason: logs and pellets, for example, do not need to be imported, are available all year round, can be easily stored and provide CO2-neutral combustion. Advanced biomass boilers are suitable not only for convenient central heating of buildings and domestic hot water heating, but also for use in industry and manufacturing. In terms of convenience and ease of use, these heat sources are similar to an oil/gas heating system.

Air and geothermal heat – free and environmentally responsible

With their excellent performance characteristics, heat pumps can be used not only for new build and modernisation of residential buildings, but also for commercial applications. Aside from heat from outdoor air, the ground or an ice store system, waste heat from industrial processes can also be used as an energy source. Comparably low operating costs, environmental protection factors and independence from oil and gas are benefits of using this proven technology. Hybrid systems with an integral heat pump module that can be used instead of an outdated oil or gas boiler are a particularly innovative solution. This also applies to gas adsorption heating appliances, which are a combination of condensing boiler and gas operated adsorption heat pump and feature around 40 percent lower fuel consumption than conventional heating technology.

Solar energy – the ideal addition

A solar thermal system for DHW heating or central heating backup is worthwhile also in conjunction with a conventional heat pump or a condensing boiler. In summer, domestic hot water can be heated exclusively using solar energy. With central heating backup, the solar thermal system can save more than 30 percent on fuel costs across the year. Using PV systems, solar energy can be converted into electric current – to be exported to the grid or for consumption on site, i.e. to be stored or, for example, to operate a heat pump.

Industrial energy systems

Efficient energy systems and plants for industrial applications play an important role in helping to reduce operating costs and harmful emissions, creating competitive advantages. In this connection, Viessmann offers extensive system solutions that safeguard an economic provision of steam up to 120 tonnes per hour, heat up to 120 MW, refrigeration/cooling up to 2 MW and up to 50 MW of power. All fuel types can be used – fossil fuels, biomass and waste heat, as well as heat from the ground or outdoor air, or waste heat from industrial processes.

Viessmann develops and realises turnkey energy concepts based on an evaluation of the overall system of energy generation, the supply structure and consumption. The analysis of all processes forms the basis for the calculation of potential and the matching of all system components. Our range is rounded off by extensive services, covering everything from engineering to commissioning and service.

Refrigeration systems

Viessmann offers innovative cooling solutions such as refrigeration and freezer units with central cooling and fully wired versions, lamellar products, system packages, temperature controlled coldrooms, refrigeration cells and units, as well as accessories and services in connection with installation and maintenance. Thanks to a strong partner network, Viessmann is able to offer its customers holistic cooling solutions. Viessmann provides one single customer interface for selling, marketing and supporting refrigeration solutions. The production sites in Germany and Finland draw on many years of expertise in the area of refrigeration technology. The amalgamation of this expertise benefits primarily customers, who obtain holistic cooling solutions from a single supplier.
