Also, if you are looking for a cost-effective alternative to a boiler of a similar type and output made by another brand.
Who Makes Viessmann boilers?
Viessmann boilers are made by The Viessmann Group in Germany. Originally founded as a locksmith company in 1917, company founder Johann Viessmann started developing boilers in 1928. Johann’s fourth generation descendants remain involved in the company to this day.
With this rich company history comes an unrivalled level of technical innovation, especially as Viessmann began its notable use of steel components in the early days of the business. To this day, the higher build quality and famous German engineering is one of the key aspects which sets Viessmann apart.
Currently, Viessmann is headquartered in Allendorf in Germany with 12 global operating sites.
Types of Viessmann boilers
Viessmann combi boilers
Known for their reliability and excellent energy efficiency, Viessmann combi boilers are packed with industry-leading technology such as integral WiFi. They also boast modern and sleek designs making them a good solution when space is at a premium.
Both the Vitodens 100-W Combi and Vitodens 200-W Combi range are rated as some of the best boilers made by Viessmann, including across their other boiler types. In fact we rated the Vitodens 100 as one of our best combi boilers.
For those who need heating and hot water on demand, combi boilers are a great choice. If you are looking to replace an existing combi boiler with a new Viessmann boiler, the process should be straightforward.
Viessmann system boilers
System boilers store hot water and take their water directly from the mains. While they require a storage tank, the Viessmann system boilers can provide greater hot water capacity than combi boilers.
The 200-W range is one to consider if it meets your usage needs. That’s because it shares many of the core features of the 200-W combi range.
Viessmann regular boilers
Viessmann regular boilers are in the form of conventional open vent heat-only boilers.
Choosing a Viessmann regular boiler is necessary for properties with high demand for heating and hot water in addition to low water pressure.
Due to needing a cold water tank, an expansion vessel and a hot water cylinder, regular boilers suit older properties where the pipework wouldn’t cope with the demands of a more modern system.
Viessmann boiler models and price guide
As you might expect, the answer to ‘How much does a new Viessmann boiler cost?’ will depend on various factors.
Based on our research, we found the cost of Viessmann boilers to range between £790 and £3,287.
On the whole, we found Viessmann to offer some very affordable options based on the unit cost of the boiler alone.
However, one thing to remember is that depending on where you purchase your boiler from, the installer will not only charge for installation, but they will also factor in the cost of the boiler. It is sometimes the case that installers pass on any discounts to their customers, but this is not always the case.
So, you should collect several quotes factoring in the following average Viessmann boiler prices to help you choose an installer.

But some of the most common features that set Viessmann boilers apart include:
- Excellent build quality (i.e. stainless steel heat exchangers)
- Fantastic energy efficiency
- Compact space saving designs
- Weather compensation features to ensure continual ambient indoor temperatures
- Integrated WiFi including being mobile app compatible
- Quiet operation
Considering the top aspects which customers look for when purchasing a new boiler, it’s safe to say that Viessmann ticks all the boxes, especially where energy efficiency and smart technology are concerned.
A typical feature of German-engineered brands, Viessmann has also invested in the build quality of their boilers. Durable internal components can make all the difference, especially given boilers are subject to heavy use.
Viessmann boiler installation
When looking to buy a new Viessmann boiler, it’s not just the cost of the boiler itself to factor in but also the installation fees.
Based on our research, we’ve found the typical installation costs for a Viessmann boiler to be between £1,200 and £1,700.
Depending on the installer you choose, the total cost of a new boiler can sometimes be reduced, especially if the installer is able to pass on any trade discounts to their customers. That’s why it’s worth collecting several quotes before you make your decision.
As with all boiler installations, the engineer must be gas safe registered as a minimum. Opting for an installer with more experience or accreditations may cost more initially, but could save you money in the long run due to a better quality installation.
Another top tip is to look for plumbing and heating engineers that are accredited by Viessmann. If an engineer is on this very select list, it means they have trained at the UK Viessmann academy.
