Viessmann Vitodens 200-W, 1.9 - 25 kW, DHW

Product detailed description

The Vitodens 200-W (combi) wall-mounted gas condensing boiler is ideally suited for flats or family houses. It can be mounted on the wall in bathroom corners or in storage rooms without any problems. The Vitodens 200-W (combi) also finds its place above a kitchen worktop, washing machine, or dryer. For anyone who values economy and a long service life, only high-grade stainless steel comes into consideration as a material. That is why the Vitodens 200-W (combi) boiler is also equipped with an Inox-Radial heating surface made of high-grade stainless steel, which offers the necessary reliability and guarantees a permanently high level of use of the combustion heat. 

FEATURES OF THE VITODENS 200-W (combi) BOILER 

Swivel display: Convenient operation in your field of view - Thanks to the higher-mounted 7-inch colour touch display, you can operate the Vitodens 200-W conveniently at eye level.

Lambda Pro

 

Another technical innovation from Viessmann is the fully automatic combustion control Lambda Pro. It automatically adapts to all types of gas and every flue gas system. In this way it ensures clean and efficient combustion. It also includes automatic adaptation of the flue gas draught.

 

Inox-Radial heat exchanger made of high-grade steel: Efficient with a long service life

 

The difference always lies in the stainless steel. The Inox-Radial heat exchanger made of high-grade, corrosion-resistant stainless steel is the core of the Vitodens 200-W (combi) units. It converts the energy input into heat with particular efficiency. Practically without losses, with an efficiency level of 98 percent, which is hardly possible to beat. And that comes together with the safety of quality stainless steel with an exceptionally long service life.

SIMPLE OPERATION

 

You can operate it completely simply and intuitively via smartphone, tablet, or directly on the large 7-inch colour touch display with adjustable height. The new electronic platform is characterised by very simple, clear operation and an understated design. It allows you to set heating appliances with a direct or a mixed heating circuit very comfortably. Clearly visible text and graphic indicators guide you through all the menu points. And thanks to the energy cockpit you have a complete overview of your energy consumption.

 

 

 

ViCare APP

Vitodens wall-mounted gas condensing boilers with the new electronic platform have an integrated WiFi interface. This allows a direct internet connection whenever needed. Through the ViCare app, operating the heating system is completely simple and intuitive. It creates a connection to the digital service and is in direct contact with the local specialist partner.

 

ViCare uses the GPS function of the mobile phone on request and thus detects the distance from the heating appliance. If the set distance is exceeded, the room temperature is automatically lowered. You can also add the ViCare thermostat to the system to enjoy even greater comfort and efficiency.

 

The app offers the following functions:

 

●  You have an overview of the state of the whole system in real time.

 

●  With a swipe of your finger you select the desired room temperature.

 

●  You set the desired hot water temperature.

 

●  Using the heating time assistant you can set switching times for heating and hot water in just a few steps.

 

●  Display of the current outdoor temperature.

 

●  Display of the temperature history over the last few days.

 

  

The ViCare app gives you an overview of the current operating state of the heating system. This gives you security and makes everything more predictable for you. Thanks to this you can program different switching times for each day according to your needs. 

 

In addition, it is possible to select normal or party mode in the app. Party mode can extend the heating period when you have a longer celebration with guests and want to keep the warmth for longer. There is also a quick-select saving mode available. It lowers the temperature when you are away from home. Not to mention a one-off hot water boost if you want to take a long bath. 

 

Normal and party mode is available for users with both Android and Apple devices. Please note that the control of your heating system must support this function. 

 

Current appliance status and direct connection to an experienced specialist 

 

In addition, the ViCare app offers automatic messages with a current description of your appliance's status. This way you can identify in time whether there is a problem or whether everything is fine. Similarly, through the ViCare app you have a direct line to a specialist partner as soon as a message appears on the heating appliance.  

 

Possible error messages are easy to recognise, because the ViCare app works through a traffic-light system: 

 

● Green: Everything is fine.

 

● Yellow: Maintenance is needed.

 

● Red: A problem has occurred.

 

If the field is red, the contact for a specialist partner is automatically displayed. For this function it is enough to select just the details of the chosen specialist partner and save them in the app. Another option is to connect the specialist partner directly to the heating system. This requires a service authorisation. You can do it with just two clicks. This allows the specialist partner to detect faults in time and possibly even fix them remotely or come to you with the right spare parts. 

 

Installing the ViCare app

 

Installing the ViCare app is easier than you think. 

The following prerequisites apply:

●  Internet connection (a data plan independent of time and volume limits).

●  Smartphones with the Apple iOS or Google Android operating system (the current version needs to be downloaded from the relevant store).

●  Viessmann Vitoconnect 100 internet interface, type OPTO 1.

●  Viessmann gas appliances installed from 2004, heat pumps installed from 2010, and solid fuel heating appliances installed from 2016. You can get precise compatibility information from your authorised specialist partner. 

 

Once the ViCare system has been installed and activated, the specialist partner will, based on your choice, be able to monitor your system using the Vitoguide app. 

 

 

ViCare THERMOSTAT 

 

 

 

You can also extend the system with a digital ViCare thermostat and enjoy even greater comfort and efficiency.

 

Note: The thermostat is not included in the package, it can be ordered as an option.

Frequently Asked Questions

• How do I choose the right output for a Viessmann condensing boiler? The basis is the calculated heat loss of the heated building (most reliably from the project documentation or an energy certificate). If you don't have a project, you can estimate roughly 60-100 W per m² of floor area for a commonly insulated house built after 2000, or 100-150 W/m² for an older, uninsulated house - the exact figure varies depending on the number of floors, room height, the number and quality of windows, and the building's orientation. An oversized boiler switches on and off more often (so-called cycling), which shortens its lifespan and reduces efficiency; an undersized boiler, on the other hand, cannot heat the house sufficiently on freezing days.

This particular Viessmann model is supplied in the output range of 1.9 - 25 kW. For a boiler type with output modulation, always choose according to the highest demand (the coldest days of the year), since the boiler can regulate its output downward on its own.

• Why is a condensing boiler more economical than a classic one? A condensing boiler also uses the heat hidden in the water vapour produced when burning gas - in a classic boiler this leaves unused through the flue, while in a condensing boiler it is cooled below the so-called dew point, the vapour condenses, and the released heat is returned to the heating circuit. Thanks to this, condensing boilers achieve an efficiency of approximately 105-110% relative to the calorific value of the gas, compared to the usual 85-92% for classic boilers.
• What type of flue gas discharge does this boiler need? Most modern condensing boilers are so-called turbo boilers (with a sealed combustion chamber) and require a coaxial (concentric) or separate flue gas discharge and combustion air supply routed through the perimeter wall or roof - so a functional chimney is not needed. You can find the exact type and maximum length of the discharge (according to a diameter of 60/100 or 80/125 mm) in the technical documentation for the specific model, or consult our customer service.
• What does the ErP energy class stated for the boiler mean? This is a mandatory efficiency label for heating appliances under the EU ErP (Ecodesign) directive, similar to the energy labels on refrigerators. Condensing boilers commonly achieve class A, or even higher in combination with room control (e.g. A+ when using weather-compensated control and a room thermostat).
• Can I install and connect this boiler myself? No. Connection to the natural gas supply, the electrical network, and the flue gas discharge is by law exclusively the job of a person with the relevant authorisation (most often an authorised service technician of the given brand or a gas appliance inspection technician). After installation, the boiler must be commissioned by the manufacturer's authorised service, which is usually also a condition for the warranty to be valid.
• What about servicing and the warranty? Most manufacturers require a regular annual service inspection by an authorised service centre in order for the warranty to remain valid even after its standard expiry (an extended warranty with regular servicing is common especially with the Vaillant, Protherm, and Viessmann brands). You can find the exact warranty conditions in the warranty card supplied with the boiler.
• What is included in the delivery of this specific product? The exact contents of the package (the boiler itself, possibly a hot water tank, room control, and other accessories in the case of a set) are stated in the product name and in its technical parameters higher up on this page.
