Next generation fuel cell boiler is launched

May 1st 2019

Viessmann will launch its new Vitovalor PT2 fuel cell micro combined heat and power (mCHP) boiler at this year's Installer2019, May 7-9 at the Ricoh Arena Coventry, and the All-Energy Show in Glasgow on May 15-16 2019 at SEC Glasgow.

Under the new, stricter EU energy labelling scale, which comes into force in October 2019, Vitovalor PT2 will have the highest possible Energy-related Product (ErP) rating of A+++. This corresponds to an annual seasonal efficiency of up to 192%, making it a serious alternative to heat pump systems. Not only is the Vitovalor easier than a heat pump to add to an existing heating system, it has a 40,000 kWh heat load demand, double that of an air source heat pump, and generates electricity as well as heat. It can generate enough electricity to cover the basic demands of an average household, save up to 40% of household energy consumption and reduce CO2 emissions by up to 30% compared to separate heat and power generation.

Darren McMahon, Viessmann Marketing Director, commented, “This is Viessmann’s third fuel cell product in less than five years, reflecting the investment by Viessmann in this technology. Over 2,000 units were installed in Europe last year. Vitovalor PT2 has even higher levels of efficiency and is super-easy to install and operate, making it more attractive to a growing installer base and to customers. We're anticipating a great deal of interest in this new product.”

Now with fully-integrated hydraulics and a footprint of just 0.72m2, the new Vitovalor comes in pre-assembled modules that are exceptionally easy to install. The unit includes a 220-litre integrated stainless steel hot water cylinder that replaces its predecessor’s 45-litre cylinder. This makes it more suitable for larger properties. The new Vitovalor is now available in four heating outputs – 11, 19, 25 and 30 kW.

The Vitovalor PT2 is equipped with Viessmann’s brand new E3 control platform, which provides faster and more reliable communications between the end-user, installer and Viessmann. The system is quicker to assemble thanks to fewer flue and pipe connections.


At Installer2019, as well as unveiling the Vitovalor PT2, Viessman will be revealing some new domestic gas boiler innovations for the UK market. Installers are also welcome to try and set a fastest lap on a Panasonic Jaguar Racing Formula E driving simulator.


At All-Energy, Viessmann will also be showing the Vitocrossal 100, a floor-standing commercial boiler that has proved extremely successful because of its exceptionally compact size and manoeuvrability; the new Vitocal 200-G PRO, a heat pump up to 100 kW for residential and commercial buildings and the Vitobloc 200, a reliable, economical and environmentally friendly CHP unit suitable for a range of residential, commercial and industrial applications.
