Micro CHP Fuel Cell
Boilers & Heating Systems
Proven and reliable: Fuel cell technology from Viessmann and Panasonic
For Viessmann, innovating without giving top priority to reliability and durability would be unimaginable. So, for our new fuel cell boiler, we once again turned to proven technology. This is why the Vitovalor was developed in cooperation with Panasonic. The fuel cell module in the Vitovalor is sourced from this renowned multinational electronics company – which has manufactured more than 34,000 appliances in series production for the Japanese market.
This combined heat and power (CHP) solution generates electricity and useful heat simultaneously, giving you a highly efficient solution that can help you to reduce your energy bills and cut your carbon footprint. Similar in size to a standard domestic boiler, our CHP systems are ideal for use in a range of environments, including detached or semi-detached homes and small commercial buildings.
Powered by a compact fuel cell, these CHP boilers produce electricity that can be used on site to power a range of appliances, while any excess electricity can be exported to the grid. At the same time, our fuel cell CHP solutions harness the heat generated during this process to produce hot water for use in your heating and hot water systems.
Just like a conventional gas boiler, most micro CHP heating systems are powered by natural gas, but our cutting-edge design can also use bio natural gas.
The Benefits
Reduce costs and emissions
Proven and reliable technology
The latest innovation in heating technology
The incredibly efficient, cutting-edge Vitovalor PT2 represents the latest in heating technology. It provides simultaneous heating and hot water using advanced fuel cell technology to convert hydrogen into energy, offering independence from rising electricity prices. The system combines heat and power generation on a very small footprint and offers considerably higher electrical efficiency than that available through current combined heat and power (CHP) solutions; making it the ideal future-thinking energy centre for modern family homes.
The benchmark for sustainable power generation
How the Vitovalor PT2 Works
The Vitovalor is a fuel cell heating appliance that uses the principle of cogeneration to generate both power and heat. To do so, the fuel cell requires not only oxygen but also hydrogen, which is obtained from natural gas in an earlier process.
This technology, especially developed for detached and semi-detached houses, runs at a very high overall level of efficiency and is designed for power-optimised operation.
Construction
The Vitovalor PT2 consists of two units: a fuel cell module and a gas condensing module for covering peak loads. The two units can be transported separately, enabling fast installation even in basement rooms where space is tight. The first unit of the Vitovalor, made by Panasonic, houses the reformer, inverter and fuel cell stack (a series of multiple fuel cells). Before the direct current generated by the fuel cell is fed into the household power circuit, the built-in inverter converts it into alternating current.
The second unit of the Vitovalor serves primarily to provide heat during times of peak demand. That is, when it is very cold outside or when a lot of hot water is required at short notice. It consists of a gas fuel cell appliance, a DHW cylinder, a heat exchanger and a heating water buffer cylinder with integral indirect coil for DHW heating. Other components in the second unit are a weather-compensated control unit, hydraulic components and an electricity meter. Both units are supplied via a common gas line. They also share a common flue system, which makes installation as easy as for a wall mounted gas condensing boiler.
