Replacing your old heating system

When replacing your old boiler with one of Vaillant's efficient wall-hung gas boilers, you can continually save up to 30% more energy and the same on costs. Plus it delivers the maximum comfort for your home. Besides this, Vaillant heating systems are durable, robust and particularly quiet.

Modernise your heating system with Vaillant

To run a modernisation project means not only to replace one thing. It's linked to a bunch of ideas which mostly affect the whole building to get best results.

But what needs to be considered by modernising the heating system? The old system consumes too much energy – you quickly notice it in your wallet.

You will benefit a lot more from a new heating system than you might imagine: Operating costs will decrease noticeably without any loss of comfort. Even after many years, a modern heating system provides comfort in your life.

For your modernisation project you can choose between different technologies, which perfectly fit to your needs. No matter, if you choose a compact and energy-saving gas condensing technology or an efficient and quiet heat pump. Vaillant offers the right technology that perfectly fits to your project and needs.

Vaillant helps you to find a solution that goes easy on the environment, saves money in the long term and meets your needs.

Our heating systems can provide you with a lot more than a warm and cozy home, as there are many different products to combine like heat generators, photovoltaic or solar thermal, ventilation, storages, that will store the hot water and heating control via app.

E.g. a Vaillant air-to-water heat pump generates heat for your home using outside air as the main energy source. The system ensures highest comfort and energy efficiency at the same time. And as a perfect all-round, it offers heating, cooling and hot water.
