Secure and future-proof The perfect heating sytem for your home.

Always the right decision

At Vaillant, you will find a large selection of climate-friendly heating systems that offer the right solution for every home. They convince not only with tested and durable quality, but above all with future-proof technology. So that you can benefit from your new heating system for a particularly long time - no matter what happens.


Climate-friendly heating technology

Heat pumps are particularly climate-friendly because they obtain about 2/3 of their energy from the environment. This makes them future-proof because the environmental heat is always available. This is also the reason why heat pumps receive the highest government subsidies*.

Meanwhile, heat pumps are no longer only suitable for new buildings - for example, our aroTHERM plus air-source heat pump is perfect for climate-friendly modernisation. Due to its high flow temperatures and small footprint, it is ideally suited for this purpose.

A resource-saving system

If it is not possible to use a heat pump alone in your home, you still don't have to do without it: A hybrid heating system consisting of a heat pump with gas condensing boiler is used if you have a high energy demand and require particularly high flow temperatures.

One advantage: you can continue to use your existing gas heating system in the future in a resource-saving way by supplementing it with a new Vaillant heat pump. The gas appliance can then be used for peak load when your heat demand is higher. If you need a new gas condensing boiler, we also offer particularly efficient products here, such as the ecoTEC plus and ecoTEC exclusive.

Independence on the roof

The system combination of a heat pump with a photovoltaic system provides you with a maximally efficient heating system. The self-generated PV electricity can be used directly to operate the heat pump - or for other appliances in your household, e.g. the washing machine or the TV set. By using your own electricity, you become significantly less dependent on energy providers and rising electricity prices. Ask your heating contractor - they will be happy to advise you on the subject of photovoltaics.

Replacement FAQ Frequently asked questions.

  • Heating replacement - what do I have to expect?

    At present, the duration of the heating replacement is significantly influenced by the availability of individual components and products. In addition, the market is determined by an increased number of enquiries, which is why the specialist companies are currently very busy. Please understand this and allow sufficient time to make an appointment with your heating contractor.

    Normally, a heating system replacement is a simple and clean process. In the first step, our specially trained specialist company looks at the structural conditions in order to adapt its recommendation to the conditions on site if necessary. The next step is the actual installation.

  • Is the request of an online offer binding?

    No, the enquiry is completely non-binding. With our service, we want to ensure that you quickly and reliably find the best heating system and the right heating contractor for your individual needs. Whether you accept the proposal of our specialist partner is, of course, entirely up to you.

  • What are the delivery times like at the moment?

    We recommend that you order the heat pump from your specialist tradesman as early as possible so as not to lose any time - in addition to the currently long delivery times and the time your tradesman needs for the precise planning and design of the heat pump. It is best to calculate with a lead time of several months. You can find more information here.

    If you choose a heat pump from Vaillant now, you are choosing a quality product from which you will benefit for a particularly long time.

*Please note that there is no legal entitlement to any subsidies. For example, the state subsidises heat pumps with 25 % - there is a further 5 % bonus for a heat pump with the heat source water, waste water or ground or for heat pumps with natural refrigerant. For the replacement of an old functioning oil, coal and night storage heating system as well as gas heating (condition: older than 20 years, except for gas floor heating systems) you receive an additional 10 % subsidy, provided that the building is no longer heated with fossil fuels. Funding condition according to the BEG guideline for individual measures (BEG EM) is an energy consumption and efficiency display since 01.01.2023. You can find more information in our funding guide.
