Viessmann Boilers Reviews

Viessmann produces various heating equipment for domestic, commercial, and industrial use. Their product line includes gas and oil boilers, air and ground source heat pumps, and solar solutions.

Viessmann designs products with sustainability in mind. This results in some of the most energy-efficient boilers in the UK, like their 200-W gas and LPG boiler which is 98% efficient.

A key feature of Viessmann gas condensing boilers is their patented stainless steel heat exchanger. It has great efficiency and doesn’t degrade over time, unlike aluminium heat exchangers.

Overall, Viessmann boilers are recognised for their reliability, durability, and energy efficiency. We think Viessmann produce some of the best boilers in the world today.

Boilerhut review

Here at Boilerhut we think Viessmann make some of the best boilers in the world. Big statement.

Their build quality is fantastic. They only use the best materials, ensuring that boiler components last a long time. For example, their stainless steel heat exchanger.

Most companies and boiler models still use aluminium for their heat exchangers. Unfortunatley, aluminium doesn’t stay very efficient over it’s lifespan. This means every year of use an aluminium heat exchanger will lose efficiency which costs you money.

Stainless steel don’t lose efficiency at all. In fact, it gets better for the first year or so.

Their customer service is always great. When we install a Viessmann boiler we become the customers first point of contact, and that’s where we differ from other installers. We want to look after customers for the life of that boiler.

We know what it can do, how it was installed and how to work with Viessmann if there are any issues at all. The integrated WiFi means we can monitor the boiler from our head office and even fix certain issues that might arise…without having to visit your home.

Do things go wrong?

Yes of course, manufacturing isn’t perfect for any business. But if an issue is found and the boiler has been serviced correctly Boilerhut and Viessmann will work together to fix your boiler. Under the 10 to 12-year warranty (model dependent), all parts and labour are covered.

If you are looking for a new boiler, we can help. We have great pricing on Viessmann boilers and can often beat many other premium brands and installers – whilst still being able to look after you for 10 years.

We can often install a boiler the next day. We’re 5* rated on Trustpilot and have finance options available. Quotes are no-obligation and instantly available after a few questions.

Viessmann boilers are a great choice for many households. But, like all brands, there are advantages and disadvantages. We think that you should be aware of all the details before choosing.

Viessmann advantages

Long lifespan: Viessmann boilers are built with high-quality components that contribute to their extended lifespan. This is further enhanced by the incorporation of quality parts like the Inox-Radial stainless steel heat exchanger, which promotes long-term efficiency.

Quiet operation: Viessmann boilers are quiet, ensuring a peaceful home environment.

High efficiency: Viessmann boilers are among the most efficient on the market, with many models operating at 98% efficiency. This translates into significant energy savings and lower heating costs.

Weather compensation: Viessmann boilers incorporate a range of smart heating features, including weather compensation. This system compares the outdoor temperature to the thermostat settings and adjusts the boiler’s operation accordingly, ensuring optimal heating efficiency and comfort.

Extended 10 or 12-year warranty: While a standard 5-year warranty is provided, Boilerhut can extend it to 10 years (on the 050 and 200 models) and 12 years (on the 100-W model) as we’re a Viessmann premium installer. This extended warranty provides peace of mind, knowing that your home heating system will receive the necessary care. As long as the manufacturer service plan is followed, the Viessmann boiler warranty covers individual parts within the boiler, such as the signature stainless steel heat exchanger.

Viessmann disadvantages

Higher cost: Viessmann boilers can be more expensive than some competitors, such as Baxi and Vaillant. However, if you get a quote with Boilerhut you may be surprised. Often a premium Viessmann boiler and installation will be cheaper than our competitors.

Occasional system errors: Like other brands, Viessmann boilers are not immune to occasional errors and faults. The system does show error codes to assist in troubleshooting or informing your boiler engineer.


Viessmann boilers are well-regarded for their super-efficiency, dependability and ease of use. This is backed by excellent customer support and long warranties.

Viessmann boilers offer a combination of great features. This is why we chose to partner with them: if we didn’t think they were good, we wouldn’t install them.

Their range suits a lot of different homes and family requirements. They are a premium product with industry-leading components. In our experience, Viessmann boilers do their job well and for a long time. Not only this, they will save you money compared to older boilers and a lot of competitor models.
