Buying a New Viessmann Heating System - Tips and Information

Step One: Preliminary Research

Before you choose a Viessmann heating system and sign the purchase agreement, there are a few things you need to clarify. To avoid unpleasant surprises, it’s important to plan your purchase carefully. Start by setting a budget. Remember that a heating system is more than just the heat generator itself: depending on the new heating system you choose, you may need a cylinder, a storage room, a gas connection, or a well. With a Viessmann air-source heat pump, for example, you don’t have to worry about any of these aspects.

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

• Should your existing heating system be supplemented or completely updated?
• Should you plan for a heating system in new construction?
• Should you switch to another energy source?
• What is the condition of the building?
• How many people live in the building? What is the heating requirement?
• Is there room for a storage room or a cylinder?
• What does my own energy use behavior look like?

What are the reasons to buy a new heating system?

Essentially, there are three different scenarios: the heating system is broken and needs to be replaced, you’re planning a modernization project, or a heating system is needed for a new building. The motivations for the latter option vary. A new Viessmann heating system not only operates much more efficiently than a 20-year-old boiler in the basement, but also allows you to save on heating costs.

Moreover, heating systems often no longer simply provide heat and hot water. Innovation, digitalization, and, above all, environmental considerations are playing an increasingly important role. With a new heat pump from Viessmann, you can heat your home using, for example, air or geothermal energy. Furthermore, a fuel cell heating system from Viessmann offers not only environmental benefits but also the advantages of technical innovation.

Buying a new heating system – but which one?

If you’re considering a Viessmann heating system, our selection offers a wide range of options. You can select and customize the right model to suit your needs. First and foremost, you have a choice of various energy sources:

• Gas
• Oil
• Electricity
• Wood
• Ecological energy

Depending on your choice, systems range from a compact wall-mounted gas boiler, an electric underfloor heating system , or an air-source heat pump, to various combination options. It often makes sense to combine two systems, such as a gas boiler and a solar thermal system. Whether this is a sensible combination should be discussed with one of our sales partners on-site.

The new heating system from Viessmann must be suitable

A new Viessmann heating system should not only fit your budget and usage patterns. The building itself, and in particular its thermal insulation, are also important factors in choosing the right heating system for your home.

For example, some heating systems are particularly suitable for new buildings. In this case, Viessmann offers a range of options to provide your home with warmth:

• Gas heating system
• oil heating system
• Wood heating system
• Heat pump
• Micro-CHP and fuel cell
• Hybrid heating system

But heating isn’t the only thing Viessmann equipment can achieve. New buildings, in particular, also require ventilation and/or power generation. Ventilation and heating can be combined effectively – using a Vitovent 300-F with an air-source heat pump. Alternatively, you can cover part of the heat pump’s electricity needs with a dedicated rooftop photovoltaic system.
