Viessmann Vitodens 111-W Combi Boiler Overview
The Viessmann Vitodens 111-W combi boiler packs three standout features that make it a popular choice for modern homes: an integrated 46-litre hot water cylinder, cutting-edge heating technology, and smart controls.
You'll appreciate the MatriX-Plus burner that runs quietly while delivering impressive 98% efficiency. The stainless steel heat exchanger guarantees long-lasting performance, while the Lambda Pro controller automatically adjusts to different gas types – including up to 20% hydrogen mixtures.
What's really convenient is the WiFi connectivity that lets you control your heating through the ViCare app.
Whether you're in a cosy apartment or spacious house, this compact unit (900x600x480mm) can handle multiple hot water demands simultaneously.
The intuitive LCD display makes daily operation a breeze, and you can even add weather compensation for ideal comfort.
Viessmann Vitodens 111-W Combi Boiler Performance and Efficiency
Outstanding performance defines the Viessmann Vitodens 111-W combi boiler, delivering an impressive 35kW output for both heating and hot water needs. You'll love the integrated 46-litre stainless steel tank that can fill your bath in under 10 minutes, with a flow rate exceeding 18 l/min.
| Feature | Benefit |
|---|---|
| A-rating | Lower energy bills |
| 98% efficiency | Maximum fuel usage |
| 1:6 modulation | Precise temperature control |
| H2-ready | Future-proof investment |
The boiler's Inox-Radial heat exchanger and MatriX cylinder burner work together to maximise efficiency. You'll notice the difference in your energy bills, thanks to its up to 98% efficiency rating. Plus, it's ready for the future with its ability to handle a 20% hydrogen blend in natural gas.
Viessmann Vitodens 111-W Combi Boiler Pros and Cons
Making sense of the Viessmann Vitodens 111-W's strengths and limitations will help you decide if it's the right fit for your home.
You'll love the impressive 18 litres per minute hot water flow rate and the built-in 46-litre storage tank. This means you can fill your bath in under 10 minutes while someone else runs the kitchen tap – no more morning rush hour battles!
The 94% efficiency rating and hydrogen-ready capability make it future-proof, while the WiFi connectivity lets you control your heating from your phone.
However, there are some trade-offs to contemplate.
The boiler's larger size means it won't fit in standard kitchen cupboards, and it comes with a higher price tag than typical combis.
You'll also need annual servicing to maintain the warranty – though that's a small price for 12 years of coverage.
How Does The Viessmann Vitodens 111-W Combi Boiler Compare To Similar Models From Other Manufacturers?
When stacking up against its competitors, Viessmann's Vitodens 111-W stands out with some impressive advantages.
Its 46L integrated cylinder trumps the Vaillant ecoTEC plus's 20L storage and offers a built-in storage solution that the Worcester Bosch Greenstar 8000 Style doesn't have at all.
While the Worcester Bosch matches the Vitodens' 18 l/min flow rate, you'll get better efficiency from the Vitodens at 94% compared to the Vaillant's 85%.
The Vitodens also comes with smart features like cylinder loading and weather compensation that you won't find in comparable models.
There's one small trade-off – the Vitodens' warranty is shorter at 5 years (though extendable to 10) compared to Worcester's standard 10-year coverage.
But given its superior storage capacity and efficiency, it's a minor compromise.

How Much Does A Viessmann Vitodens 111-W Combi Boiler Cost?
Looking to invest in a Viessmann Vitodens 111-W? You'll need to budget between £2,500 and £3,276 for a complete installation, depending on your specific requirements.
The boiler unit itself ranges from £1,836 for the 25kW model to £1,976 for the 32kW version (including VAT). While these prices might make your wallet wince a bit, remember you're paying for premium quality that's about £800 more than standard combis.
Installation costs typically run £500-£1,000, plus around £300 for essential extras like filters and flues. If you're converting from a system boiler to this combi, expect to pay about £4,000.
The good news? The 111-W's impressive 98% energy efficiency rating means you'll likely recoup some costs through lower energy bills over time.
Plus, its smart WiFi features help optimise your heating expenses.
