The Vitovalor PT2 fuel cell heating system from Viessmann
Vitovalor PT2 (formerly Vitovalor 300-P), the fuel cell from Viessmann, is the ideal energy centre for the modern detached and two-family house. The system combines heat and power generation on a very small footprint. The Vitovalor PT2 offers considerably higher electrical efficiency than that available through current combined heat and power (CHP) solutions. This reduces the amount of heat extracted and makes the fuel cell heating appliance particularly suitable for use in new build and renovation projects.
The Vitovalor PT2 is the innovative alternative for decentralised power generation. Against the backdrop of discussions on energy and rising electricity prices, this solution is steadily gaining in relevance. In the future, CHP technology will be an important part of power generation.
Vitovalor PT2 is the fuel cell for larger homes
With 30.8 kW, the Vitovalor PT2 provides enough thermal output to cover the entire heat demand of a detached or two-family house. The maximum amount of electrical energy generated over the course of a day (18 kWh) is enough to cover the basic needs of an average household. The integral gas condensing boiler switches on automatically when the heat generated by the fuel cell module is insufficient, such as at peak times or when a lot of hot water is required for a brief period.
Vitovalor scoops two more UK awards in 2018
The fuel cell mCHP appliance won the 2018 Innovation of the Year: Technology - Physical and also Home Energy Product of the Year, at the Energy Awards ceremony in London.
The awards ceremony brought together over 600 of the most senior operators in the energy market, both local and international, to recognise and celebrate the very best of the energy industry. For more information, see Energy Awards 2018.

How the Vitovalor PT2 works
The Viessmann Vitovalor PT2 basically uses the principle of combined heat and power generation. It thus generates electricity and heat at the same time. The prerequisites for this are oxygen and hydrogen obtained from natural gas. This is because, unlike conventional heating systems, so-called "cold" combustion occurs. This means that through a chemical reaction of oxygen and hydrogen, chemical energy is converted to thermal as well as electrical energy. You can find out exactly how this works under How the fuel cell works.
The design of the Vitovalor PT2 fuel cell in detail
The Vitovalor PT2 fuel cell heating appliance consists of two units: the fuel cell module and the peak load module with gas condensing boiler, integral 220 litre stainless steel DHW cylinder, plus hydraulics, sensors and control unit. The units are compact, visually matched and together require a footprint of only 0.72 square metres.
Central source of information – the control unit of the Vitovalor PT2
The Vitovalor PT2 is equipped with a large colour touchscreen that allows you, as the system owner, to keep an eye on everything – from system pressure, boiler temperature of integrated peak load boiler, flow temperatures of the various heating circuits, to the current DHW temperature. In addition, the control unit provides information about the outside temperature as well as the thermal output of the fuel cell itself. If you connect the system to the ViCare app, you can conveniently control and monitor this function while on the move.
In addition, the Vitovalor PT2 has an integrated electricity, gas and heat metering function. This is particularly useful for providing billing information for state electricity subsidies and energy tax rebates.
Self-learning energy manager – an advantage of the Vitovalor PT2
A major advantage of the Vitovalor PT2 is the integrated energy manager, which is capable of learning and reacts to the individual needs in the home. The Vitovalor only starts when sufficiently long runtimes are expected. This ensures that the fuel cell produces electricity that can actually be consumed within the home.
Energy transition – a community effort
There are many good reasons to generate your own electricity. These include greater independence from rising electricity prices, fossil fuels and conventional power supply utilities, as well as making your very own contribution to the energy transition. With ViShare, you become part of the Viessmann Group's Energy Community and purchase low-cost 100% green electricity. The contractual partner in the ViShare Energy Community is Energy Market Solutions GmbH (EMS), a subsidiary of the Viessmann Group.
