Viessmann Vitodens 200-W Review

Doing a Viessmann Vitodens 200-W Review is easy-peasy, because it’s the best boiler available in the UK right now.

There is nothing else in the UK market even close to this.

A lot of manufacturers would like to call their models the best boiler, but it’s wishful thinking, without much substance.

Before we take a look at one of the best boilers in the world, let’s take a brief look at the manufacturer first:

Viessmann Vitodens 200-W Review – Viessmann App Information

For Home Thermostats and central heating, Viessmann’s ‘ViCare’ app offers new possibilities for internet-controlled heating operation, and with an intuitive and simple graphic interface, the system gives full control to the user over one heating circuit. A mere swipe of the screen allows you to set the required room temperature, as well as the option to switch between ‘standard’ and ‘party mode’.

The ViCare App can react accordingly to where you are in relation to the property. So for instance, if you’re leaving the property, you can lower the temperature with just a simple command.

On top of this, the app will always provide tips on how you can save energy – making a hugely beneficial addition to your heating system.

On top of this option, there are also many other brands with impressive products in the smart thermostat range. For a detailed comparison for two of the most famous brands, take a look at our Nest vs Hive comparison article.

Vitotrol App

As well as ‘ViCare’, Viessmann has also developed the ‘Vitotrol’ App that can be equipped along with any Vitotronic 200 control unit installed. The basic benefits for this app include:

  • Convenient operation via smartphone app
  • Allows users to access information on your heating system at any time
  • Heat distribution control
  • Ideal for all domestic properties
  • Can be used with all floor standing and wall-mounted Viessmann boilers
  • Any important alerts are displayed in easy-to-read format



High-Performance Heat Exchanger


stainless steel heat exchanger

Much like in other Viessmann boilers, the stainless steel Inox-Radial heat exchanger is extremely durable and offers a corrosion-resistant solution that other boilers in the current market don’t supply.

Stainless steel is highly resistant to corrosion for many pH levels.  For aluminum, if the proper fluids are not used to produce and maintain a narrow pH range, it can corrode much faster. and your heat exchanger will be permanently damaged – costing you more in the long run.

So while stainless steel might be more expensive to source or manufacture compared to aluminum, the investment will be more than worth it further down the line due to its corrosion-resistant qualities.

You can always appreciate the visual quality of the Viessmann 200-W with its sleek and professional look, but it’s also a very quiet piece of technology. With its internal design allowing it to operate at a noise level of only 39 decibels at a maximum of 26 kW, it works at a perfectly acceptable volume, even in busier areas of the house such as the kitchen.

Built to last with durability, and a high efficiency rate of up to 98%, it’s an incredibly easy choice.


Viessmann Vitodens 200-W Review – Weather Compensation

Viessmann Vitodens 200-W Review, Weather Compensation

All Viessmann boilers utilise the important weather compensation technology. And this Viessmann Vitodens 200-W Review won’t be complete without Weather Compensation.

But how does Weather Compensation work?

  • A sensor positioned on the north facing wall picks up information on the temperature outside and then sends back to the boiler controls.
  • A temperature sensor is installed on a north facing wall, which is wired to the internal controls of your boiler.
  • When there are changes in the outside temperature, the boiler will compensate by increasing or decreasing the temperature accordingly.

But what does this mean to the average user? You’ll be cosy and warm inside your house, and won’t even notice that the temperature has changed outside.

How does Weather Compensation Save Energy and Money?

Think about how the outside temperature drops at night, and how heat can then be lost through the walls. Even though improved insulation can definitely help, weather compensation seeks to minimise this.

Unfortunately, not everyone will have the luxury of excellent wall insulation – which is where weather compensation comes in.

Weather compensation uses data collected to determine when temperatures might fall again. By using this information, the boiler can then raise the temperature of the radiator and keep the property comfortably heated.

Without this weather compensation technology, the temperature is dependent on a room thermostat, which only takes effect after the inside of the building is too hot or too cold.
