Solutions and benefits thanks to Kermi

Kermi system x-optimised

In the Kermi system x-optimised heat generation, heat storage, heat control, heat transfer, and living space ventilation interact perfectly. Interfaces are optimised, energy losses between system components minimised, and energy efficiency improved many times over.

The x-fold optimisation of every component in the interaction considerably increases the efficiency of the whole system even further. Depending on the type of construction, type of house, and fittings, with the Kermi system x-optimised and using Kermi Smart Home energy savings of up to 36 % are possible.

Kermi system x-optimised

Heating control at home. Easy while out and about.

Simple and easy control of your heating system with your heat pump on your tablet.

Controlling the heat in your own home when you want and where you want - Kermi Smart Home makes it possible. The intelligent system for digital, location-independent control of the "Kermi system x-optimised" conveniently conducts all the components of the heating system via smartphone and tablet. Other devices such as home lighting or shutters can be incorporated into the system.

Using x-center base, the headquarters of Kermi Smart Home, you can easily control your x-change dynamic heat pumps while at home or while out and about. This allows you to control individual rooms as well as the entire heating system using timer programmes or scene creation, such as Holiday or Party modes. For intelligent living and maximum comfort for a sense of well-being.

x-center control

For an optimal result. And a regulated process.

The x-center controller controls the Kermi system x-optimised and guarantees efficient and resource-saving operation of the heating system by regulating the flow temperature. Equipped with a clearly arranged display, the x-center controller is proving to be extremely user-friendly in the process. We intentionally kept it easy to use and decided in favour of a intuitively identifiable screen design. Thanks to this user-oriented user interface with clear menu guidance, it is straightforward and really easy to use the Kermi system x-optimised. This means the device can be controlled without any problems after being given brief instructions when the system is commissioned.

therm-x2 steel panel radiators. The radiator for the housing sector.

With the innovative, patented x2-technology the energy-saving therm-x2 radiator is setting new standards. With serial flow through the radiator panels, in comparison to conventional  radiators, it saves up to 11 % more energy, generates up to 100 % more comfortable radiant heat and its heating period is up to 25 % faster. Another huge advantage: Thanks to these strengths, the therm-x2 harmonises perfectly with modern heat sources, in particular with the heat pump.

Comprehensive programme. Short delivery times.

The plus for the construction and housing sector

100 % more radiant heat can save costs. Fewer complaints because of cold radiators can definitely save bother and costs. 

Sample calculation:
30 min craftsman's work (60 € / hr.) + travel to and from the site
-> 30 € + 30 € = 60 € / complaint
Complaint in approx. 3 % of the housing stock
For example, 30000 dwellings x 3 % = 900 complaints / year
-> 900 x 60 € = 54000 € savings / year

100% more radiant heat can save costs

Wowi valve. The valve insert for the housing sector.

Even though most radiators are hydraulically balanced in theory, this balance is no longer provided immediately deviations from the design basis occur. Particularly at peak times with high heating demands, the radiators can be supplied at different levels.

The Wowi valve from Kermi is the solution for this problem.

To carry out the hydraulic balancing, the new valve insert with integrated flow control only needs to be adjusted to the required amount of water depending on the radiator output and system temperatures. And that is extremely simple: The specialist tradesman will find the right adjustment value for the respective radiator at a glance thanks to an appropriate overview. The valve then controls the maximum flow independently of any differential pressure fluctuations which may occur.

This ensures that oversupplying the radiators is prevented, even when other residents turn their radiators on or off. Unnecessary complaints, for example if the radiators are too cold, are now a thing of the past.

Valve insert with dynamic flow control.

  • Even supply of all radiators in the loop
  • No complaints from residents because of radiators that are too cold, for example
  • Cost saving, as differential pressure controllers in the loop usually become superfluous
  • Supports trouble-free operation even for existing buildings with an unknown pipe system
  • Time savings, as unavoidable differential pressure dependent determination of radiator adjustment values no longer necessary
  • Saving energy costs due to high energy efficiency
  • Grant amounting to 30 % through the subsidy programme “Optimisation of the heating system” from the Federal Ministry of Economics and Technology (BMWi)
