H2 Ready Viessmann Vitodens combi boiler

With the Vitodens combi boiler being a hydrogen ready boiler it means that it 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 quick, fixed-price boiler quotes 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 full boiler installation, it’s probably underpriced for what it does. You may be thinking how? with all these new features this fancy boiler should come with a fancy price tag.

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 review

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!

Viessmann Vitodens 100-w 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). 

Viessmann Vitodens 100-w Compact Boiler

Making sure a boiler can fit in kitchen cupboards ensures that a 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! If you are looking for an even more compact boiler with the same amount of reliability, then why not take a look at the Viessmann Vitodens 050-w.

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 Bosch 8000 but if you chose to do so, it isn’t an eyesore.

Imagine an easy-to-use boiler that anyone can use. Well, that’s what Viessmann has 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. 

Viessmann Vitodens 100-w 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 review

The Viessmann Vitodens 100-w system boiler is a great boiler for large houses. Its 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 its own hot water cylinders for sale.

Viessmann Vitodens 100 Boilers Reviews 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. 

Viessmann Vitodens 100-w Performance Review – 9/10

Viessmann Vitodens 100-w boiler review  trust pilot

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. 

Viessmann Vitodens 100-w Reliability Review – 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.

Viessmann Vitodens 100-w Pricing Review – 10/10

We think the Vitodens 100 is only beaten on value for money by the smaller boiler in the Vitodens range, the 050-w. When you put together everything, performance, reliability, and the market-leading warranty, the new boiler price could be higher and still offer great value for money. We haven’t taken the looks into consideration as it’s a boiler, who cares?

Viessmann Vitodens 100-w boiler review warranty

Viessmann Vitodens 100-w Warranty Review- 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 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.

Viessmann Vitodens 100-w Gas Condensing Boiler Review Overall Score 9.25/10

9.25 was the highest score we had given any boiler until its little brother, the new Vitodens 050-w came along. 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.

Viessmann Vitodens 100 Boiler Thermostats & Controls

Viessmann Vitodens 100-w boiler review vicare smart thermostat

Keeping your home at the perfect temperature at the right times is a gift. Warm when you get out of bed and warm when you get home from work on a winter’s night.

You can use a regular thermostat with the Vitodens 100 or a smart thermostat. The choice is yours. Let’s take a look at what you can use.

Viessmann Vi Care Smart Thermostat.

Viessmann’s standard thermostat enables you to set temperatures manually and timings for your boiler to come on at certain times of the day. This is great and easy to use if you are in and out of your house at regular times.

Hive & Nest compatablity

The Vitodens 100 is compatible with both Hive & Nest.

These smart thermostats are universal so if you currently have one of these you can simply connect this up to your new Viessman boiler using the built-in WiFi.

Again, these smart thermostats enable you to control your heating from anywhere you can get an internet connection. 

Viessmann Vitodens 100-W Review Final overview

The Vitodens 100-w is one of the best boilers for the price we have come across. We also love the Worcester Bosch 4000, so why not take a quick look at that combi boiler before your buy,but it no doubt will be a big hit and installed in thousands of homes across the UK.
