Today we are looking at the brand new for 2021 Viessmann Vitodens 050-W 25kW & 30kW combi boiler review and the Viessmann Vitodens 050-W system boiler review.

What’s new about the new release Viessmann 050

With a new boiler comes new features, and Viessmann have really futureproofed the 050. They’ve given it Hydrogen ready capabilities, built-in wifi and a super user-friendly touch screen display. They have also given it a facelift with a slick black fascia at the bottom just to finish it off. We think it looks great.

Choosing the new Vitodens 050 over other boilers

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 to 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.

That’s why we here at Boiler Central have vetted several types of boilers, filters, and associated materials to come up with the utmost reliable and low maintenance systems that cater to a range of homes and family sizes.

A Which Best Buy Viessmann Combi boiler Review

The Viessmann Vitodens 050-w combination boiler is one of the reasons that trip advisor gives 4.5-star reviews to Viessmann.

Customers rate the Vitodens 050-w for being such a reliable, compact, lightweight and quiet operational combi boiler.

The Vitodens 050-W has a reasonable price tag for the quality of this gas condensing boiler.

The Viessmann Vitodens 050-w combination boiler supplies heating and hot water but is only a 1 unit system meaning it does not take up a large amount of space.

kitchen cupboard fit combi boiler

The Viessmann Vitodens combi comes in a 25kW and 30kW output flow rate, meaning it is reviewed to suit homes with up to 3 bedrooms for both new build homes and older homes.

The boiler comes with a 7-year warranty and can connect to the Tado smart app allowing you to control your heating system wherever you are in the world. However if purchased through Boiler Central, you can get a huge 12-year warranty on all Viessmann boilers.

A Which Best Buy Viessmann System Boiler Review

The Viessmann Vitodens 050-w is also available as a gas system boiler. The system boiler is part of the Viessmann boilers which are known for their reliability.

System boilers are great if you have a home with 2 or more bathrooms and have a demand to have hot water to multiple taps at once.

The system boilers store the hot water. Unlike the Viessmann combi boiler, the Vitodens 050 system comes with a boiler to live in the kitchen cupboard and a hot water cylinder to live in the airing cupboard.

A low-cost gas condensing boiler with a compact design, the Vitodens 050 offers a super quiet operation that integrates into any home effortlessly without compromising on quality.

The Viessmann 050-W is the ideal new boiler installation for both new builds and any home renovations.

Stainless Steel Heat Exchangers: 

Viessmann 050-w Stainless Steel Exchanger

Like the aforementioned comparison to BMW, Viessmann, a fellow German brand, engineered their 050-W boiler to last.

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 at 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 boiler reviews compare how good both manufacturers really are.

Is the Viessmann Vitodens 050-W really the best choice compared to the Worcester Bosch Greenstar 25-i?

Viessmann 050 boiler in kitchen

Absolutely! To start, the Viessmann 050-W boiler has a water flow rate at 12 litres/min, whereas the Worcester-Bosch Greenstar 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 the Worcester-Bosch’s Aluminium heat exchanger and with 98% efficiency compared to the Worcester-Bosch’s 94%.

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

Viessmann is the winner!

Viessmann 050-W – The benefits:

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

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

Coupled with it already being particularly low noise 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. 

It’s even perfect for multi-level buildings and flats, being able to have 5 boilers connected to a vertical flue system over several floors. 

It’s low installed height makes it easier for 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 make it easy for your annual boiler service to be performed.
