Viessmann Vitodens 100-w combi boiler – Whats new?

There is a lot of updating and revamping going on in the boiler world, and Viessmann have wasted no time in making sure that their brand new 100-w is getting ahead of the times. With the misleading media speculation over the ‘banning’ of gas boilers, the 100-w is ready to be snapped up by worried homeowners.  

Being H2 ready means that this boiler is ‘exempt’ from being banned as it is capable of running on a mix of natural gas and hydrogen. It is only boilers that can run solely on natural gas that will be removed from production, but by the time the new rules kick in we envisage that all new boilers will be H2 ready. 

An LCD touch screen display, built-in Wifi and a facelift are all part of what makes this boiler an upgrade on the old Vitodens 100, but does this come at a price? Get a quick, fixed price online now for this boiler with Boiler Central.

How much does the Vitodens 100 cost?

This is a premium boiler and at around £2,100 including installation, it’s probably underpriced for what it does.

The new Vitodens 100 cost about £0 (yes, zero) more than the old one, even with all this new stuff. This is Viessmanns best selling boiler, it had to be the new boiler cost had to be the same and be aimed at the same market.

The main features of the new Vitodens 100-w

We have highlighted some of the outstanding features of the Vitodens 100 already,we’ll look at them here in more depth and some of the key points about this boiler that make it what we believe, superb value for money. If you think the Vitodens 100 is out of your price range, try boiler finance to see if you can pay monthly instead!

H2 Ready (Hydrogen Ready)

Hydrogen looks like it is going to be the next green fuel to be used to power boilers. The Vitodens 100-w is capable of working with 20% hydrogen mixed into natural gas to keep carbon emissions down, so you can buy this boiler in confidence knowing you have at least 12 years peace of mind (that’s the available warranty length). 

Compact Boiler

Making sure a boiler can fit in kitchen cupboards ensures that the boiler is an option for more people in the UK. If space is lacking in your home and you have a boiler in your kitchen as many people do, it’s usually in a cupboard. If you’re moving your new boiler, always check by measuring first though!  

New Look Boiler

The Vitdodens 100-w has been given a facelift. A black band at the bottoms has been added to give this boiler some character rather than a big white lump. We’re not convinced you’d exactly want to have it on show like other new boilers such as the Worcester 8000 but if you chose to do so, it isn’t an eyesore. 

LCD Touchscreen Display

Imagine an easy to use boiler that anyone can use. Well, that’s what Viessmann have done. With a very simple design and easy to use controls, there’s no more guesswork involved. If you want to make it any easier, you can control your boiler through the ViCare app instead. 

Built-in WiFi & Remote Access

You may think that built-in WiFi is a bit unnecessary, but when you look at the benefits you can see why it’s a selling point of the Vitodens 100-w. You can control your heating from your phone, tablet or computer using the app, and in the rare event a Viessmann boiler has any issues, an engineer can actually remotely take control of your boiler to diagnose any problems. How good is that for letting you get on with your busy life!

Viessmann Vitodens 100-w System Boiler

The Viessmann Vitodens 100-w system boiler is a great boiler for large houses. It’s power is perfect and it’s economically even better. The Vitodens 100 system boiler requires a hot water cylinder to work, so ensure that this is definitely the type of boiler you need. If you don’t have a hot water tank already, you would have to buy one and pay for the installation on top of your boiler. Viessmann does have their own hot water cylinders for sale.

Viessmann Vitodens 100 Boilers Verdict

Like any good review, we have given this boiler scores out of 10 in the main areas that people look for in boilers such as performance and reliability, pricing and warranty. Let’s see how well the Vitodens 100 scores. 

Performance – 9/10

The Vitodens 100-w is a high-performance boiler. It’s designed as such and it delivers. It’s economical and easy to use. We think the LCD display could be a little better and more intuitive but it’s simple and works. 

Reliability – 9/10

Being a German company, you get all the reliability you would expect. Built to last and given a 12-year warranty as a big stamp of approval from Viessmann means they are confident in their own work, and rightly so. The old Vitodens 100 was reliable, this is even more so. The new boilers also come with full TrustPilot endorsement for that extra backup.

Pricing – 10/10

We think the Vitodens 100 is unrivalled value for money. When you put together everything, performance, reliability and the market-leading warranty, this boiler could be priced higher and still offer great value for money. We haven’t taken the looks into consideration as it’s a boiler, who cares?

Warranty.- 9.5/10

Technically we should have given the Vitodens 100-w 10 out of 10 because they offer 12 years warranty which is on par with other industry-leading warranties. We have knocked half a mark of due to the fact you have to find a Viessmann trained installer. The good news is they aren’t hard to find! There are some T’s and C’s to follow but they’re the same across all boiler manufacturers.

Overall Score 9.25/10

9.25 is the highest score we have given any boiler. We love the Vitodens 100-w. It just does everything well without being too flashy. It is a boiler after all and you want it to tick over nicely and do its job without causing you any problems or hitting you in the pocket. This boiler does that from the start with its value for money price and ease of installation. This boiler is a great back boiler replacement in terms of cost and output.
