Here you can find answers to frequently asked questions. We always strive to put all available information on our products at your disposal.
Please understand that we can not answer any technical questions on your heating system. To do this, an analysis of the problem on location is indispensable. In such cases, please contact a qualified specialist installer.

All radiators with a centre connection can also be operated in single pipe systems. Depending on the design, either a one-pipe radiator valve or a one-pipe radiator valve with a thermostat valve, for example from the eccolution system, is required.
Kermi compact radiators can be connected with the aid of a special separating plug even with a thermowell valve (lancer valve).
The corresponding separating plug for Kermi steel panel radiators is available in accessories. Additional products available on request.
Design and bathroom radiators from Kermi are factory-equipped with all popular heat sources, whether oil or gas. If you want to be completely independent of the hot water central heating, choose one of the Kermi models for electric operation. Delivered complete with electronically controlled heating rod, heat transfer liquid and controller. Simply connect to the power supply and feel its benefits. A cost- and time-saving solution primarily for old buildings.
With the new electrical solutions from Kermi, with additional electric operation, you can for example also enjoy perfect heating comfort between the seasons and always when your normal central heating is not enough. And incidentally, you will also always have beautifully warm towels.
If you decide to go for electric operation of design and bathroom radiators, you are deciding in favour of the most advanced technology and ultimate operating convenience. There are four different solutions available to choose from, depending on your tastes and requirements.
The accessories include a touch-up stick (article number ZK00100001 RAL 9016) as well as a spray can 150 ml (article number ZK00160001 RAL 9016) and a can of paint 500 g (article number ZK00090001 RAL 9016) which you can use to touch up minor damage to the paintwork.
You can also buy these parts from your qualified specialist installer or from specialist wholesalers.
Window niches for radiators used to be standard in most houses to install the very deep radiators. This solution is disadvantageous because it impedes convection, i.e. the circulation of warm air. The niche in the wall also weakens the insulation effect of the wall. An additional heat shield on the radiator can be useful.
If the required room temperature is reached, then don't worry about this. The thermostat controls the water supply such that this aspect of the radiator occurs in case of partial quantities of water. A remedy is provided by using a radiator with x2-technology where the front panel is flowed through first. The front panel becomes uniformly warm and the rear panel serves as a shield against the cold external wall during the part load operation (90 % of the heating period).
For more detailed information, please contact your heating engineer.
Most Kermi design radiators are suitable for recording heating costs using a heating costs allocator. As the positioning of the acquisition devices differ between the manufacturers, please contact the respective manufacturer for the details.
In general, plan steel panel radiators can have evaporation counters installed on them. Please contact the manufacturer of the acquisition device on this. As the positioning of the acquisition devices differ between the manufacturers.
Refer to the details in the technical documents on this, therm-x2 steel panel radiator technology.
To ensure that the heating system works without any problems, the flow rate of the hot water needs to be adjusted to the heat demand of every individual radiator. Kermi valve radiators are preset in the factory according to the standard heat output of the radiator. This saves energy costs and ensures optimal heating comfort.
Lift the plastic clip of the side panel and unscrew anticlockwise. From BL 1000 onwards with Plan-HK or BL 1400 with Profile-HK remove the retaining bracket from the top cover.
Installation of the top grille is carried out in the reverse order!
Remove a side cover at a slight angle from the radiator (see figure) and remove it from its attachment hooks after lifting the top cover.
Then separate the top cover by lifting it at one side and moving the second side cover.
For radiators which have not been used for a long time, the tappet may have become stuck due to deposits or the annular gap in the cross section aperture may be shifted by particles. After very long down times, real incrustation can be formed due to the precipitation from substances in the water. It often helps to remove the thermostatic sensor head and to move the tappet several times with an object which is not too hard (handle of hammer). To install it, move the thermostatic sensor head to position 5.
In many cases, the problems can be avoided by turning the radiator thermostats to position 3 in empty apartments. The valve is then kept continuously in motion and deposits can not be formed.
In some cases (heavy incrustation) the only alternative that remains is to replace the valve insert. Then as well it is important to ensure that times where the valve is at a standstill are avoided.
The valve "tapping" suggests that the feed and return valve on the radiator have been mixed up.
You can check this by allowing the radiator to cool down. If connected correctly, then afterwards when the valve is open, the pipe pointing to the middle should get warm.
If this in not the case, then a reverse manifold needs to be installed.

You can find the heat output of our radiators in the technical information of the relevant product. Kindly note correct selection of temperature pairing when determining the heat output. Determination of the standard heat output according to EN 442 is based on temperature pairing 75/65/20 °C. In practice, lower temperatures are common today. Please contact your specialist installer for the final calculation.
