TECHNOLOGY BROCHURE Both highly efficient and renewable A futureproof energy mix in a single appliance.

Heating with hybrid appliances – futureproof as standard When it comes to energy and heating, there are a lot of solutions out there. The decision to go with one heating system or another is not an easy one. One thing's for certain: prices for fossil fuels and electricity are subject to strong fluctuations in the long term. So it's all the better if you do not have to rely on a single energy source for your heating, but can instead invest in a futureproof hybrid solution. With hybrid appliances, two independent heat generators are integrated in a single unit: a gas condensing boiler is combined...

Compact hybrid appliance from Viessmann: A futureproof energy mix in a single appliance The Vitocaldens 222-F compact hybrid appliance combines two energy sources in a single appliance: a highly efficient source with an advanced condensing boiler for gas, and a renewable source with a heat pump that uses free environmental heat. With economy always in mind Hybrid appliances from Viessmann amalgamate the benefits of a heat pump with those of a highly efficient condensing boiler. Consequently, in operation they always achieve an optimum mix of renewable and Anyone wanting greater independence from...

10 year guarantee on stainless steel heat exchangers for oil/gas condensing boilers up to 150 kW For conditions and product overview, see www.viessmann.de/garantie Condensing boiler for gas with stainless steel Inox-Radial heat exchanger: long term reliability and efficiency The condensing boiler: efficiency with a stainless steel heat exchanger Condensing technology is one of the most efficient forms of generating heat. The reason: this heating technology not only recovers the heat that occurs during the combustion of gas. It also utilises the residual heat in the flue gases for heating – heat...

CONTROL UNIT Which energy source is the most cost effective for heating? It's easily controlled – completely automatically The Vitocal 250-S split air source heat pump and the Vitocaldens 222-F compact hybrid appliance are equipped with a Vitotronic 200 control unit. They also have an integral intelligent Hybrid Pro Control energy manager. Heating systems are normally controlled subject either to room or outside temperature. The intelligent Hybrid Pro Control energy manager thinks ahead and regulates the system with variable settings. The user can customise these settings and change them at any...

Hybrid Pro Control thinks of everything. Even electricity from a photovoltaic system When calculating the most cost effective operating mode, the Hybrid Pro Control energy manager also takes into account electricity generated on site by a photovoltaic system. Low cost or environmentally responsible? You, the user, can choose: the heating system can be run to prioritise either environmental responsibility or cost effectiveness. Simply select your preferred setting; Hybrid Pro Control does the rest. Whether away or at home: everything is always under control Even when you're away from home, you...

Viessmann combines highly efficient condensing technology with the utilisation of free environmental energy The Vitocaldens 222-F compact hybrid appliance makes it possible to find the optimum combination of renewable and conventional energy sources. Constantly fluctuating energy prices mean it is difficult for consumers to make the right decision in favour of both economically and environmentally responsible heating systems that will remain viable in future. The compact hybrid appliance now offers a futureproof solution for the modernisation of heating systems. Futureproof modernisation Powerful...

The perfect solution for any application: In the compact hybrid appliance from Viessmann, heat is provided by a powerful gas condensing boiler and a heat pump. The two systems operate on a flexible, alternating basis or supplement one another. Your heating system automatically determines which system should be used for more economical or environmentally responsible heating based on the currently set energy prices. This depends on which operating mode you previously selected. DHW at any time – even when demand is high. Ideally, the hot water is generated economically using the heat pump. Compact,...

When it comes to retrofitting existing condensing boilers with free environmental energy, Viessmann has the right system for you The Vitocal 250-S split air source heat pump is ideal for use in conjunction with a wall mounted or floorstanding condensing boiler. heat pump takes over heating operation, depending on the selected reference value and according to the currently set energy costs. A heat pump makes an ideal addition to a heating system for gas or oil. For a futureproof solution, and to protect the environment. Not only do you utilise free environmental energy, but the heating system can...

Ideal for retrofitting existing condensing boilers: In a detached house, the Vitocal 250-S split air source heat pump covers up to 80 percent of the demand with free environmental energy plus electricity.

Split air source heat pump The Vitocal 250-S supplements existing floorstanding or wall mounted oil or gas condensing boilers up to 30 kW. Depending on the size, the output of the heat pump itself is up to 19.5 kW. This means that it covers the majority of the annual heat load, saving costs – in a detached house, up to 80 percent of the required energy for heating and DHW can be covered with free environmental energy plus electricity. Hybrid Pro Control: the right mix of energy for maximum efficiency The Vitotronic 200 control unit with the Hybrid Pro Control energy manager controls both the heat...
