By drawing on a diverse range of examples, this brochure shows how the most varied energy solutions can be put into practice with the comprehensive range from Viessmann. Everything from a single source – with completely matched systems.
At home 6
Today's new builds are designed for maximum efficiency. Above all, this means using systems that obtain energy from the environment. Not only heat, but also power, to achieve the greatest possible level of independence from the public grid.
At work 16 The ideal working environment is also dependent on pleasant room temperatures. Many renewable heating solutions are possible, using energy from the ambient air, groundwater or the ground.
Production 24
In production plants and commercial enterprises, energy is required in all of its various forms – as hot water, steam and also, of course, electricity. Viessmann offers efficient, powerful technology for all applications.
Hospitals 28
High cost pressures, and the need for a continual supply of energy, mean that particularly efficient solutions are required in the healthcare sector. Modernising a heating system can significantly reduce the energy demand and energy costs. 4/5
Public and leisure facilities 32
Public buildings for cultural and leisure activities have different requirements for heat provision. Whilst one may need large volumes of hot water for its spa areas, another requires low temperatures for the preservation of cultural artefacts.
Retail and tourism 38
Shopping centres and retail businesses require relatively little hot water, but their customers expect pleasant temperatures and good ventilation. In hotels, on the other hand, a convenient hot water supply plays an important role.
Local authorities 44
Rural areas are best placed to take advantage of renewable energy generation. A local heating network can supply all of the households in a bioenergy village efficiently and cheaply with heat and power from renewable sources.
The company 48
Viessmann is one of the world's leading manufacturers of efficient systems for heat, cooling, steam and decentralised power generation. As a third generation family run business, the company has been supplying heating systems with low emissions for many decades.

Two Vitobloc 200 CHP units, each with an
output of 140 kWel and 207 kWth, and four Vitomax 200-LW hot water boilers, each with an output of 2.3 MW, were installed in the new plant room of the Ökumenisches Hainich Klinikum (Hainich Ecumenical Hospital). The two CHP units cover the base load of heat required. At low outside temperatures, the hot water boilers start up as well. The power Vitobloc 200 CHP units (left) and four Vitomax 200-LW generated at the same time by the CHP units hot water boilers in the plant room of Hainich Ecumenical Hospital is used by the hospital itself and provides around 40 percent of the energy required.
The demand in a medical facility for domestic hot water of the highest possible quality necessitates pasteurisation at a temperature of 70 °C. This is achieved without chemical additives. The entire energy system is integrated into the building management system via BACnet. 30/31

Schwarzwald-Baar Hospital, Titisee-Neustadt
The energy centre at the Schwarzwald-Baar Hospital is equipped with an advanced energy system from Viessmann for a reliable supply of heat, hot water and steam.
The base load is covered by two Vitoflex 300-FSR biomass boilers with flat moving grate combustion. The woodchips required for this are sourced locally.

Leisure park, Schwarzwald, Titisee-Neustadt
The "Badeparadies Schwarzwald" leisure park has a heat demand of 13,000 MWh. To meet this, a Vitobloc 200 CHP unit supplies the base load all year round. At around 8000 operating hours, its main job is to generate power for the leisure park itself. The simultaneously generated heat is used for central heating and DHW, resulting in an energy utilisation level of over 90 percent for this CHP system. In the summer, the CHP unit becomes the sole provider of power and heat.
Independence from fossil fuels The main provider of heat in winter is a Vitoflex 300-UF woodchip system that Vitoflex 300-UF biomass boiler with underfeed combustion supplies around 60 percent of the heating energy. The operators deliberately chose wood as their fuel type, as this makes them less dependent on fossil fuels. Two Vitoplex 300 low temperature boilers spring into action if there is a higher demand. Vitoflex 300-UF biomass boiler
CO2 neutral operation The plant room only expels flue gas and conditioned water vapour from its chimney, as the flue gas is cleaned using advanced depluming systems. This enables compliance with statutory limits without difficulty. Vitobloc 200 CHP unit The concept in place at this leisure park is advantageous in that it makes efficient use of energy and employs wood as a regenerative fuel. This allows CO2 neutral heat generation, as the carbon dioxide released into the atmosphere is balanced out by the amount that the wood absorbed during its lifetime.

Wettesingen bioenergy village
In the bioenergy village of Wettesingen near Kassel, approximately 200 homes receive their entire heat supply from renewables. The technology used comes from Viessmann's comprehensive product range. An existing biogas plant was supplemented with a CHP unit and three wood combustion systems, as well as a low temperature gas boiler with biogas burner for peak loads. The overall thermal output is approximately 2600 kW, while the electrical output is 900 kW.
30 percent reduction in heating bills The price for heating in the Wettesingen bioenergy village is based on all investment and running costs. Compared to the costs for individual heating systems that use fuel oil, the community's heat supply is now around 30 percent cheaper. Since the price of oil and gas can be expected to continue to rise, the price benefit will become even greater in future. As is the case with the CHP units, the Vitoplex 200 also runs on biogas. As part of ongoing expansion plans, the system was supplemented with a containerised heating system, including a
Vitoplex 200 low temperature boiler that Vitobloc 200 burns biogas. The boiler was installed in the CHP unit container at the factory and the container itself simply needed to be set down on the prepared foundations.
