A perfect match – System technology

"The whole is greater than the sum of its parts". Following this philosophy, Viessmann supplies more than high quality, reliable and effective heating components.

In fact, all products are part of a matching total concept, where all components complement one another. After all, only perfect interaction between all system components can draw out the maximum potential of our innovative leading technology.

Viessmann system technology incorporates everything you need for a reliable and economical heating system: From the Vitotronic control unit with wireless remote control, powerful Vitocell DHW cylinders for the highest DHW convenience, right up to high grade solar thermal systems for cost effective central heating backup.


Weather compensation

With ever increasing fuel bills and the need to be as eco-friendly as possible, it's important that we all look for ways to save fuel and carbon emissions - and money!

All gas boilers now have to be condensing boilers and this represents a huge step forward in environmentally friendly heating, with fuel savings of up to 35% compared to conventional boilers.

But there is a way to save even more - up to 15% in fact, with just a simple outdoor sensor and some very clever Weather Compensation controls, available with the Vitodens range of
condensing boilers.

For a relatively small investment you'll not only save up to 15% more fuel each year but you'll also enjoy an incredibly comfortable home - with a pleasant indoor temperature - whatever the weather.

Standard control units from 1.5 to 2000 kW

With increasing demands for efficient, multi mode and user-friendly heating systems, the control unit gains ever more importance. As a response to this demand, Viessmann now offers a standard range of control units in the shape of the Vitotronic 200/300 that is suitable for all small boilers, wall mounted boilers, medium-sized boilers and heat pumps.

Operation with user prompts

Operation with user prompts is easy and intuitive. This is supported by standard controls, a large backlit graphic display with several plain text lines, a high contrast monochrome depiction and a context-sensitive help function accessible via the "?" key. Special functions, such as heating curve, solar yield and switching times are depicted graphically.


Remote control units

With their attractive design and white, high-gloss casing, the remote controls in the new Vitotronic control unit range are ideal for use in living spaces.

Thanks to a standardised operating philosophy, the new Vitotronic units are straightforward and intuitive to use and quickly provide an overview of the heating system at all times.


Vitotrol app

The Viessmann Vitotrol app enables you to operate Viessmann heating systems equipped with Vitotronic control units. Operation from anywhere and at any time is easy, intuitive and convenient. Alongside its operating functions, the Vitotrol app features general and context-sensitive help functions. The Vitotrol app is available for mobile devices with iOS or Android operating systems.

In order to operate the app, the wall mounted boilers / small boilers / medium-sized boilers / heat pumps / wood boilers with Vitotronic 200 (see "Usage requirements" for control unit types) must be equipped with the Vitocom 100 LAN1 interface and linked to the domestic broadband router. Configuration of the DSL router is not required.


Domestic hot water cylinders

In the Vitocell cylinder range, you'll find exactly the right DHW cylinder for your requirements. Depending on your DHW demand and the installation conditions, you can choose a DHW cylinder for installation adjacent to or below the boiler.

Hygienic DHW provision

The quality of the inner surface of the DHW cylinder is crucial to providing DHW hygienically. For this reason, Viessmann relies on two high quality materials: the first being Ceraprotect enamel coating for safe, lasting protection against corrosion for the Vitocell 100 range. Secondly, stainless steel is the "guardian angel" of the Vitocell 300 range, satisfying the highest hygienic requirements.


Data communication

From holiday home and utility building to large apartment complexes - the Viessmann TeleControl range offers intelligent solutions for data communication with heating systems and building services.

This applies to all available heating systems: Oil or gas condensing boilers, medium and industrial/commercial oil/gas boilers, solar thermal systems as well as pellet boilers and heat pumps.


Freshwater modules

Freshwater modules are used for convenient and hygienic DHW heating in accordance with the instantaneous water heater principle. In contrast to conventional DHW cylinders, the drinking water is not used for storing thermal energy but instead is only heated when required, by means of a powerful plate heat exchanger. The energy for this DHW heating is drawn from a heating water buffer cylinder, which can be heated by a wide range of systems – by solar thermal systems, or by solid fuel boilers, conventional oil/gas boilers, heat pumps or other systems.
