Viessmann Vitodens Combi Boiler – What makes them so good?
If you haven’t picked up already that we think the Vitodens 100-w boiler is a top boiler, then let us convince you further. Some of the things you may not even care about in a new boiler like its stainless steel heat exchanger, flow rate, or its low weight but all matter in terms of performance, reliability, and suitability for your home.
Vitodens 100-w Performance – Getting the most from your boiler
Viessmann boilers are designed with a broad range of UK homes in mind. The Viessmann Vitodens 100-w caters for them by offering 3 different outputs (kW). This means that they are suited for small to medium-sized homes with low to high water demand. The higher the output, the better this gas-fired combination boiler will be at keeping up whilst maintaining good water pressure and maximum efficiency.
With the different outputs come different flow rates. The 26kw Vitodens 100-w has a flow rate of 10.6l/min and the Vitodens 100-w 35kw has a flow rate of 14.3 L/min.
Don’t be tempted to think you are better off just getting the larger boiler if you want to fill your bath quicker as it may not be economical for you to do so in terms of your gas bill. The higher output will burn more gas, so if you have a smaller property with low overall demand, go for a lower output to save you money!
How Reliable is the Vitodens 100-w combi boiler – Stainless Steel Heat Exchanger For Life!
Becoming renowned for reliability is something that any company selling a product would love to be. Viessmann have ensured that they use only the best internal components in their boilers such as the Inox-Radial stainless steel heat exchanger which is covered by the 10-year warranty.
This speaks volumes on its own, backing their product to the end. The Vitodens 100-w wall-mounted boilers can be hung in kitchens and close to living areas due to their quiet operation.
To ensure that the Vitodens 100-w is always performing to the best of its abilities or is not going to break down when you need it the most it protects itself with an outside temperature sensor, provides information on the current operating status & can be remotely connected to a local Viessmann trained installer for monitoring. How about that for protection.
12 Years Warranty – Peace of mind for years to come
12 years is a long time. If someone said you could have a brand new car that will last you 12 years with no extra costs on top you’d snap their hand off. This excessive warranty just shows how confident Viessmann are in their modern construction methods used in the Vitodens 100-w.
Not only is this combi boiler suitable for most homes in the UK, but it’s also suitable for your pocket in the long run. This is the only Viessmann boiler with 12 years warranty. Other combi boilers from other manufacturers such as the Worcester Bosch 8000 also come with 12 years.
To ensure that you are eligible for 12 years warranty there are certain steps you will need to take to make sure that your warranty is valid. The main one being that you must get your boiler serviced every year by a Gas Safe registered installer to make sure your heating system is in order.
Vitodens 100-w TrustPilot reviews
Other people’s experience with a brand matters. That’s why we are doing this review, but let’s take into account some real-life experiences of Viessmann Vitodens 100-w boiler owners. They hold an excellent rating on the top review platform TrustPilot, meaning they are currently rating 4.5 stars out of five for over 1000 customers.

Will the Vitodens 100-w Fit in a cupboard?
The Viessmann Vitodens 100-w has a compact design which means it will fit in most standard-sized cupboards. Its low weight, quiet operation & size mean it can be working hard to keep your home warm in the depths of winter with you probably having to remember which cupboard you chose to store it in if you should have to check on it.
If you are unsure about whether the boiler will fit in a specific cupboard and you need to get the tape measure out then the boiler is 700mm high, 400mm wide, and 350mm deep. It’s by no means the smallest boiler in the world, there are a lot smaller on the market if you need to get the right boiler for a particular space.
Viessmann Vitodens 100-w Features & Controls
Using condensing technology, 94% of the fuel used by the Viessmann Vitodens 100-w boiler is turned into heat. This in turn ensures that it produces low CO2 emissions which means it’s doing its bit for the environment too.
The matriX plus burner coupled up with the Lambda Pro technology used in the Vitodens 100-w means longevity & clean, efficient running for the lifespan of the boiler, not just at the start.
Touchscreen Display & Built-in Wifi Technology
The brand new design of the Vitodens 100-w incorporates a new LCD digital touchscreen display with built-in WiFi technology which means you can control your boiler from your phone or tablet using the ViCare thermostat and downloadable app.
This can also mean that Viessmann can remotely access your boiler to diagnose any faults with the boiler, should there ever be any.
ViCare Thermostat – Control Your Heating With Your Phone
Whilst you can always control your central heating with Viessmann’s standard boiler thermostats which work just as well as any, you can really take control of energy efficiency, domestic hot water output & how hot each room with the ViCare thermostat.

Viessmann Vitodens 100-w Vs Worcester Bosch 8000
In regards to other boilers, the most direct competitor to the Viessmann Vitodens 100-w combi boiler is the Worcester Bosch 8000 combi boiler. The Worcester 8000 has been out for over a year now and has fast become a popular choice due to its pioneering technology and not for the cupboard high gloss finish.
But where the 8000 has had its year in the sun the Vitodens 100-w offers everything the 8000 does but for slightly less money. The ostentatiousness of the 8000 is the only thing that sets it apart. The Vitodens 100-w just gets on with the job knowing how good it is. There’s not much in it, just personal preference.
Conclusion – Final Review Of The Vitodens 100-w
The Viessmann Vitodens 100-w is a clear-cut top-of-the-range combi boiler. Designed to be exactly that and priced accordingly, this powerhouse could easily be on top of the market for years to come. Coupled up with smart thermostats such as the Vicare app, Nest, or Hive, you could end up with a boiler for the future right now.
Not forgetting also that it is Hydrogen ready, which looks like it is going to be the next main clean fuel source for domestic boilers once they can get hydrogen harvesting costs down.
