In this guide, we will tell you all the background information you need to know about Viessmann to let you make an informed decision over whether this is the sort of company you want to buy from.

A Potted History of Viessmann

The Viessmann Group is a German company based in Allendorf, in the north-western state of Hesse.

It was set up in 1917 by Johann Viessmann, who set up a small workshop specialising in the construction of steel boilers. After World War II, the company was taken over by Johann’s son Hans who grew and modernised the production methods.

The 1970s saw Viessmann expand outside Germany for the first time with factories opening in first France and then Canada.

After the fall of the Berlin Wall in 1989, Viessmann expanded quickly into the new markets of Eastern Europe, while also adapting to new boiler technologies.

Today, Viessmann employs more than 12,000 people and reports annual sales of € 2.37 billion.

It is active in more than 74 countries around the world including the UK and is still run by the Viessmann family.

Viessmann has been based in the German town of Allendorf since the 1940s and this continues to be home to the company’s manufacturing base.

Viessmann has 23 production companies in 12 countries around the world but the boilers that are supplied to EU markets, and the UK, are all manufactured at its German headquarters and comply with strict German and EU manufacturing standards.

Reasons to buy a Viessmann boiler

If you are in the market for a new boiler, there are no shortage of reasons why you should consider a Viessmann boiler.

  • German Engineering – Viessmann boilers are German engineering at their finest. And at the risk of stereotyping, that means they are built to an extremely high standard and are super-efficient.
  • Long warranties – The length of a boiler’s warranty is usually an indication of how long the manufacturer expects it to last without problems. If you buy a Viessmann boiler through Heatable, you can get a 10-year warranty with most models. That is the longest boiler warranty you will find anywhere.
  • Top-notch aftercare – Viessmann offers excellent customer service. If your boiler develops a fault and is under warranty, it is their stated aim to get an engineer to you within 24 hours.
  • Environmentally friendly – Gas boilers are generally seen as being bad for the environment. But if you opt for a Viessmann boiler, you can be sure that you are buying an A-rated boiler that is as energy efficient as any gas boiler on the market right now.
  • European Reputation – Don’t just take our word for it. Viessmann’s reputation in mainland Europe goes before it. It is the most popular boiler manufacturer in most European countries and the company’s 2.4 billion Euro turnover illustrates its popularity all too clearly.
  • Cost-effective – All this quality German engineering is usually expected to cost a bit. But actually, Viessmann boilers are among the most affordable cost-effective boilers on the market right now. When you buy Viessmann, you can be confident you are getting a high-quality boiler for less.

Viessmann’s technical USPs

These are all big selling points for Viessmann, but if you want to drill down into the detail of the technical advantages of a Viessmann boiler, there is plenty to be impressed by too, including:

  • Stainless steel heat-exchanger – All Viessmann boilers include a heat exchanger made with stainless steel. This helps this vital component stay clean and last longer. It is also something Worcester Bosch don’t offer.
  • Combined PRV & condensate pipe – Your boiler’s Pressure Release Valve (PRV) and its condensate pipes usually require two holes to be put in your wall. But Viessmann has combined these into a hybrid pipe meaning one fewer hole is needed. This should make installation easier and more affordable too.
  • Built-in shock arrestors – Boilers can make all sorts of noises which is very annoying. But they don’t have to. If they have a shock arrestor, the noise they make should be reduced to a minimum. And all Viessmann boilers come with a built-in shock arrester.
  • Weather compensation device – The UK weather is very unpredictable and this can affect the temperature you want your house heated too. All Viessmann boilers are fitting with a weather compensation device which monitors the outdoor conditions and adjusts your heating accordingly. It’s very clever and a really useful feature.
  • Compact size – Compact sizes are not an optional feature with Viessmann. All their boilers come in the smallest possible sized case to save as much space as possible in your home.
  • Smart tech compatible – If you want to move into the 21st century with a smart thermostat, you can with Viessmann. All of their boilers are compatible with all the top smart thermostats.
