Viessmann Vitodens 200-W Review

Doing a Viessmann Vitodens 200-W Review is easy-peasy, because it’s literally 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:

Who are Viessmann UK?

This Viessmann Vitodens 200-W Review takes a detailed look at the winner of Which? Best Buy Boiler award for the 2nd year running in 2017 and 2018, and on track to repeat it in 2019.

Viessmann are going against Worcester Bosch and Vaillant in the fight for UK central heating dominance.  Both of its rivals have been present in the UK almost 4 times longer, and so obviously have a better foothold in the UK market.  But Viessmann have caught up quickly and are knocking at the door for UK central heating supremacy.

Just think how it could help warm your house ready for when you arrive home!

We’ve done a detailed review and FAQ article for EPH Combipack 4 which answers all your questions.





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.



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 temperature sensor is installed on a north facing wall, which is wired to the internal controls of your boiler.
  • The weather compensation sensor will send information about the outside temperature to your boiler controller constantly.
  • When there are changes in the outside temperature, the boiler will respond by increasing or decreasing the radiator temperature.

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?

If you think about how the outside temperature drops at night, then that means that heat is lost through the property walls. Better insulation helps alleviate that issue.

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

Because the outdoor weather compensation sensor detects the fall in temperature as soon as it happens, the boiler is able to raise the radiator temperature and keep the inside temperature stable.

So even if it suddenly becomes freezing outside, your boiler will react accordingly to ensure you’re always living at a comfortable temperature.

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.



Designed for lasting efficiency
