Save on heating costs with replacement radiators.

There is simply no other refurbishment measure that is as efficient as modernising a heating system. With the reductions it brings in energy costs and harmful emissions, it is a truly worthwhile investment. Ultimately, heat pumps, condensing technology, and solar panels represent the future of energy-efficient heat generation. But a new heating system pays for itself even more quickly if new, high-performance radiators are installed as well. As Kermi radiators feature the same connection dimensions, replacing older radiators is a breeze.

Subsidies for a wide range of modernisation measures are available at a national, regional, and local authority level. Your Kermi heating specialist is familiar with all the current subsidies available. It is important to note that applications must be made and approval granted before making the investment.
More information

There are many good reasons to replace your old DIN radiators today:

  • The large amount of water they contain makes DIN radiators cumbersome. Modern radiators can be finely regulated and ensure more efficient use of energy.
  • Modern radiators are considerably more powerful. They allow for lower operating temperatures and therefore save energy.
  • Replacing the heat generator requires the radiators to be adapted to the changed operating conditions.
  • With modern heat generators, such as condensing technology, heat pumps, and solar thermal energy, the savings effect can only be fully exploited once the radiators have been precisely adjusted to the new operating conditions.


  • Rust in old radiators can cause leaks.
  • Modern radiators give added value to comfortable living and residential quality, ensuring a cosy indoor climate.
  • The Kermi radiator design completes the new atmosphere you have created in your home.

Radiators with design aspirations.

Apart from the cost savings and the positive effect on the environment, design-related and practical aspects are important to consider in the process of choosing new radiators. In a modern living environment, old DIN radiators quickly look out of place. While old radiators used to be covered up and hidden, Kermi radiators become a visual highlight of every room soon after they are installed.

Easy, uncomplicated replacement with Kermi.

It is an undisputed fact that modern radiators are a sensible investment. And with Kermi, they can also be an investment that does not take much work to put in place. Whatever the connection situation is like, there’s no need to replace the existing pipes and connections.

Benefits for modernisation measures

  • Renovation and refurbishment can be performed while the property is occupied

  • Can be installed without chiselling or demolition work

  • Extremely low installation heights

  • Compatible with various floor coverings

For a long time, installing underfloor heating was a mammoth task. Not least because of the unsurpassed warmth they generate, surface temperature control systems have now become standard in both private and commercial new builds, and when carrying out modernisation work. The x-net panel heating systems from Kermi are exceptionally quick and easy to install, and are ideal for a low-cost, environmentally friendly combination of all energy-efficient heat generators, such as condensing boilers, solar systems, or heat pumps. Best of all, the efficiency and economy of the heating system grows with the size of the heat-radiating surface.
