Viessmann Vitodens 050 boiler – Whats new?

With a new boiler comes new features, and Viessmann has really future-proofed the Vitodens 050-w combi boiler, especially as they’ve given it built-in wifi for use with smart thermostats and a super user-friendly touchscreen display.

They have also given the Vitodens 050-w a facelift with a slick black fascia at the bottom just to finish it off.

We think it looks great, however, one thing that hasn’t changed though is the great price of this combi, which makes it the best boiler in its class.

Why choose the Viessmann 050 over other boilers

vitodens 050-w hydrogen ready

Viessmann is the best-selling boiler manufacturer in Europe, and let’s face it, when it comes to boilers, most of us have no clue what we are looking for, or what company to trust when it comes to supply and fit.

You probably see a lot of Viessmann vs Worcester Bosch or Ideal vs Baxi and still have no clue which would be the best heating system for your home, so here are some reasons why you should choose the new Vitodens 050-w for your home.

Compact combi boiler great for kitchen cupboards

The Vitodens 050-w is a compact combi boiler perfect for hiding in kitchen cupboards at just 700mm high, 400mm wide, and 300mm deep, making this one of the most compact combination boilers on the market. Don’t let the small dimensions of this boiler put you off though it is a very capable boiler.

Easy to install & service

Due to its compact size and the way that the Vitodens 050 is designed, it can be installed with no side access – every bit of equipment can be accessed easily from the front.

This also makes any boiler service or repairs much easier, which in turn will save you money on labour costs when out of warranty. There is just so much going on for this model.

Gas combi boiler available in 3 different outputs for homes in the UK

The Vitodens 050-w range is available in 3 different outputs so that it is more available to homes in the UK and Viessmann has changed the outputs of the Vitodens 050-w and now comes in 25kw, 30kw & 35kW

It used to come in 24kw, 29kw, and 35kw but Viessmann have ensured that this value combi can still be the choice of most homeowners with the latest introduction of the new 35kw version.

If you fancy an upgrade though completely, check out the bigger brother Vitodens 100-w combi boiler which is another range to choose from.

Vitodens 050-w 25kw combi boiler perfect for smaller homes and flats

The Vitodens 050-w 25kw combi boiler is ideal for homes with up to 3 bedrooms and 1 bathroom making this energy-efficient combi boiler great with lower hot water demand and will help keep your utility bills down.

This boiler can also modulate down so it doesn’t have to run at full power all the time, which means even less energy is used.

This gas combi boiler too can modulate its power so it only uses as much power as is needed to heat your home.

Vitodens 050 35kw combi boiler

The latest update in the Vitodens 050-w range is the introduction of the Vitodens 050-w 35kw combi boiler for homes requiring a powerful compact combi.

This really means that Viessmann has covered more bases with the introduction of this 35kw output in the same compact unit.

The price is also a massive plus point as this combi is still fantastic value for money without paying premium prices.

Before you would have had to upgrade to the Vitodens 100-w to get this output, but not anymore and we expect this to be a top selling boiler in 2024.

Built-in wifi

If you are buying a replacement boiler you’ll be glad to know they now come with built-in Wifi so you can easily connect your boiler to a Viessmann smart thermostat or mobile device.

This helps you keep track of your heating bills by letting you have more control as it means you can see how long your boiler has been on and you can control your boiler by turning it on and off from anywhere you can get an internet connection.

Similarly, if you have any issues with your boiler, a Viessmann customer service agent can remotely connect to your boiler and diagnose the issue.

Stainless steel heat exchangers

Like the aforementioned comparison to BMW, Viessmann, a fellow German brand, engineered their 050-W boiler to last, and even though this Viessmann boiler is considered a budget boiler, the stainless steel heat exchanger is far more robust than other, higher-priced brands. 

This might not mean anything to you as a consumer, however, take our word for it when we say that the heat exchanger is a likely fault point in any broken boiler, making the reliability and chance of breakdown in our Viessmann boilers far less likely is the stainless steel heat exchanger.

This gives you peace of mind that your boiler, even on a budget, will remain in working order for years to come.

That’s why Viessmann is an award-winning, and continuously upcoming boiler brand, quickly catching up to the likes of Worcester Bosch.

This is why you often now see Worcester Bosch vs Viessmann boilers reviews comparing how good both manufacturers really are.

Viessmann Vitodens 050-W vs Worcester Bosch Greenstar 4000

Absolutely! To start, the Viessmann 050-W boiler has a water flow rate of 12 litres/min, whereas the Worcester-Bosch Greenstar 4000 has a flow rate of 10 litres/min.

Also, the heat exchanger on Viessmann being stainless steel makes it a much better choice when compared to Worcester Bosch’s Aluminium heat exchanger, as stainless steel is much more reliable and likely to last.

It really is a no-brainer when it comes to budget boilers for 1, 2, and 3 bedroom homes. 

Viessmann is the winner but if you want to know more, read our Vitodens 050 vs Worcester 4000 review.

Viessmann 050-W pros and cons – the benefits:

Viessmann boiler getting installed

Guess what? It just seems to get better when it comes to the Viessmann 050-W.

The electronic boiler control unit for thermostatic / weather compensation mode is already included and integrated into the Vitodens 050-W. Oh, as well as a frost stat.

Coupled with its already particularly low noise level when in full operation and a compact, eye-catching design, the Vitodens 050-W is among the best combi boilers and of the smallest wall-mounted boilers available on the market today. 

We have yet to hear of any consistent Viessmann boiler problems too which is good considering they are installing thousands of boilers every month!

Is the Vitodens 050-w good for flats?

Apartment block

Yes, the 25kw 050-w is perfect for multi-level buildings and flats, and also being able to have 5 boilers connected to a vertical flue system over several floors. 

Its low installed height makes it easier during the replacement of old boilers, with improved access to serviceable parts such as the plate heat exchanger and inherent ease of wiring with all Viessmann boilers, making it easy for your annual boiler service to be performed.

Viessmann Vitodens 050 review – Additional options:

Analogue time switch with day program and digital time switch with the seven-day program. The time switches can be plugged into the wall-mounted boiler’s control unit.

Boiler Accessories

Hardwired analogue room thermostats (24 V) with and without day program.

Analogue wireless Viessmann room thermostat with a day program for the optimum room temperature for your home.

What is the difference between the Vitodens 050 and Vitodens 100?

The main difference between the Vitodens 050 and 100 is the performance in terms of energy efficiency. The Vitodens 050 is around 92% energy efficient, whereas the Vitodens 100 is more energy efficient at 94%.

The components such as the PCB that control the energy efficiency in the Vitodens 100-w are superior to the 050, therefore, justifying the extra cost. This also means that there is a difference in boiler modulation ratio, where the 050 manages at a ratio of 1:8 the 100 manages an even more efficient 1:10 ratio.

Which is the best combi boiler in the UK?

Well, you’re in luck, as you have found what we believe to be the best combi boiler, the Vitodens 050. When compared to the other combi boilers such as the Worcester Bosch 4000 and Ideal Logic, the Vitodens 050-w reigns supreme with its stainless steel heat exchanger, reliability and best price tag in terms of value.

The Viessmann Vitodens 050-w last thoughts:

Viessmann Vitodens 050-W boiler

Using the above Viessmann boiler review, you should be armed with the knowledge to make a considered purchase of your next boiler. If you want to consider other boiler brands, then check out the direct competitor to this boiler in our Worcester 4000 vs Viessmann Vitodens 050-w boiler review

The next boiler up from the 050-W would be the Viessmann Vitodens 100-W combi boiler. If you have high hot water demand but don’t have space for a hot water tank then why not consider the Viessmann Vitodens 111-w storage combi boiler too?
