Purchasing a new Viessmann heating system – tips and information

(Bild: © /

First step: research in advance

Before you decide on a Viessmann heating system and sign the purchase contract, there are a few points that need to be clarified. To avoid unpleasant surprises, the purchase should be well planned. Start by setting a budget. Remember that a heating system is more than the heat generator itself – depending on the new heating system that you choose, a cylinder, storage room, gas connection or borehole may be necessary. With an air source heat pump from Viessmann, for example, you don't need to be concerned about any of these aspects.

The answers to these questions should be clarified in advance by consulting an energy advisor or heating system contractor:

  • Should an existing heating system be supplemented or completely renewed?
  • Should the heating system be planned for a new build?
  • Should I change to another energy source?
  • What is the condition of the building?
  • How many occupants are there in the house? What is the heat demand?
  • Is there space for a storage room or cylinder?
  • What does my own usage behaviour look like?


What are the arguments for purchasing a new heating system?

There are essentially three different scenarios: the heating system breaks down and needs to be replaced, you're planning a modernisation project or a new build needs a heating system. The motivating factors for the latter option are different. A new heating system from Viessmann not only runs much more efficiently than the 20-year-old boiler in the cellar, but buying a new Viessmann heating system also saves on heating costs.

In addition, it is often no longer just a question of the heating system merely providing heat and hot water. What's more, innovation, digitalisation and, above all, the environmental aspect are playing an increasingly important role. With a new heat pump from Viessmann, you can heat with environmental energy from the air or the ground, for example. In addition, a fuel cell heating system from Viessmann not only has an ecological advantage, but also the benefit of technical innovation.

Purchasing a new heating system – but which one?

If you are planning to purchase a Viessmann heating system, our product range offers a wide selection of options. You can select and customise the right model according to your needs. First of all, you have a choice of different energy sources:

  • Gas
  • Oil
  • Electricity
  • Wood
  • Environmental energy

Depending on your selection, the systems range from a compact wall mounted gas boiler, an electric underfloor heating system or an air source heat pump through to various combination options. It can often be worthwhile to combine two systems such as a gas boiler and a solar thermal system. Whether or not this is a sensible combination is something that you should decide with one of our trade partners on site.


The new heating system from Viessmann has to be the right fit

A new Viessmann heating system should not only suit your budget and usage behaviour. The building itself and, in particular, its insulation are also important influencing factors when it comes to choosing the right heating system for your home.

Some heating systems are particularly suitable for new build, for example. In that case, Viessmann offers a range of options for supplying your home with heat:

But heating is not the only thing that you can achieve with Viessmann appliances. In a new build in particular you also need to consider ventilation and/or power generation. Ventilation and heating can go well together – the Vitovent  300-F along with an air source heat pump. Alternatively, you can cover some of the electricity demand of a heat pump with a dedicated photovoltaic system on the roof.
