The Viessmann Vitodens 111-w storage combi boiler is one of the best storage combi boilers available.
The Vitodens 111-w storage is a cross between a system boiler and a combi boiler whereby the external hot water cylinder is inside the boiler itself rather than in an airing cupboard or loft space. It makes the actual unit slightly bigger but it is still relatively compact.

Viessmann Vitodens 111-w boilers review
In this review, we will look at the Viessmann Vitodens 111-w benefits, price, technical specification, and anything else we can think of that will help you in deciding on whether this is the right storage combi boiler for your home.
The Vitodens 111 is a fantastic kit, but it isn’t suitable for everyone and it definitely isn’t a gas boiler for a kitchen cupboard so let’s review this innovative boiler.
Viessmann Vitodens 111 w technical specification
You must remember that this boiler isn’t a standard combi boiler.
It is designed for larger homes with higher hot water demand.
The built-in hot water tank means it can deliver a lot of hot water to multiple taps simultaneously.
This makes it larger than a typical combi boiler but saves space on the external hot water cylinder.

Viessmann Vitodens 111-w review & benefits
We have outlined some of the main features of the Vitodens 111-w storage combi, but what does this mean to you?
We have broken it down further to see if this boiler is for you.
Viessmann Vitodens 111-w dimensions
This boiler is larger than average combi boilers, with dimensions of 900mm high, 600mm wide and 480mm deep.
Therefore, it can’t be described as a compact combi boiler and won’t be fitting in most kitchen cupboards.
However, in terms of capabilities, this combi boiler can still fit in smaller spaces, making it suitable for domestic use.
It is targeted at larger homes, so there is potential for more room for the Vitodens 111.
If you’re looking for a compact combi boiler, why not try the baby brother of the Vitodens range, the Vitodens 050-w combi.
Viessmann Vitodens 111 w flow rate
This boiler’s high flow rate greatly appeals to houses with four or more occupants.
The flow rate is 18 litres per minute and can fill a bathtub in under 8 minutes. It can do this all whilst another tap is turned on!
Viessmann Vitodens 111-w Technology
This storage combi boiler has been designed to be future-proof.
Viessmann has given it built-in Wifi and an easy-to-use LED touchscreen, and it is hydrogen ready.
Built-in Wifi
The built-in Wifi means that this boiler can be used with smart thermostat technology.
Viessmann has its own smart thermostat app called ViCare.
This app means that you can control your heating from anywhere that you can get an internet connection.
It also means that you can track how much energy your home uses, which is great for saving money.
Hydrogen ready boiler
Hydrogen looks like it is going to be the fuel of the future if they can farm the hydrogen efficiently.
Being hydrogen ready means that this boiler is capable of running on a mix of hydrogen and natural gas.
This helps to lower carbon emissions and the carbon footprint.
LED touchscreen controls
Viessmann has ensured that this boiler is user-friendly with an easy-to-use touchscreen display.
All the icons and numbers are easily identifiable, and it gives you exactly the information you need to operate it.
Viessmann Vitodens 111 Storage combi review conclusion
Don’t take our word for it; there are already hundreds of reviews online regards this boiler from Viessmann.
We rate this boiler, but be careful if you are strapped for a bit of space in your home.
The price of the Vitodens isn’t cheap either, so if you don’t need all the power and performance of a storage combi boiler, you may want to consider a standard powerful combi boiler such as the 111-w’s brother, the Vitodens 100-w.
