The Vitovalor PT2 is one of the most innovative heating appliances currently on the market. It stands out on account of its high efficiency and makes users considerably more independent of electricity price rises. Certain conditions must be met for commissioning:
Please note that the PACE Funding scheme is no longer available.
Viessmann's Vitovalor is the world's first mass-produced fuel cell boiler and one of the micro-CHP products backed by PACE. By combining the production of heat and power it provides energy savings of up to 36 per cent compared to separate heat and power generation and reduces CO2 emissions by more than 30 per cent.
PACE aims to bring fuel cell micro-cogeneration technology closer to mass market affordability and to establish Europe as a global leader in the technology. PACE funding has ensured that the Vitovalor is within reach of a much greater proportion of UK homeowners. There are now around 100 heating engineers trained to fit the Vitovalor in the UK and more training planned for 2019.
The Vitovalor is designed for power-optimised operation with the longest possible runtimes. Together with a gas condensing boiler, a total heating output of 30.8 kW is available with a 220 litre unvented hot water cylinder. The ideal installation locations for the Vitovalor are well insulated detached and two-family houses with a low heat demand, such as new build and modernised existing buildings. The fuel cell heating appliance works particularly efficiently when the return temperatures are very low – ideally with an underfloor heating system. Efficient operation with radiators that have a maximum return temperature of 50 degrees Celsius is also possible.
A gas connection is required to operate the Vitovalor. Hydrogen, the actual fuel for the Vitovalor, is obtained from gas in a conversion process. You can find detailed information about this process by clicking on How the Vitovalor works. If no gas connection is currently installed, this could be arranged retrospectively. Ask your local supplier whether this would be possible.
The electrical connection is made via a 3-core power cable. If you intend to operate the Vitovalor with a photovoltaic system or another energy system, ensure that the electricity meter is set up correctly. If it is set up incorrectly, this would result in false statistical data from the energy manager. In addition, bills from the local energy supplier would not be accurate.
The Vitovalor consists of two units: the fuel cell developed by Panasonic and the gas condensing module from Viessmann. The two units can be transported separately, or sited freely in the room. As a compact heating appliance, Vitovalor requires a footprint of less than 0.72 square metres. The minimum required room height is 1800 centimetres. If the units are installed side by side, they take up a width of 1200 centimetres.
Every house has its own heat demand. Efficient operation is only possible when the output of the fuel cell heating appliance exactly matches this heat demand. If you have a heat load calculation, you should therefore bring it with you to the consultation. It contains all the important information about the property required for correctly sizing the heating system. Further information about the existing heating system, such as the year of manufacture, output and consumption, make the search process much easier and should also be provided wherever possible.
