EcoTimer
Customisable time programme for Kermi electric radiators
With EcoTimer, you can transmit a customised time programme to FKS, WKS, and WFS control units. The app establishes a Bluetooth connection with the control unit. Once the app has detected the room control unit, it is possible to rename the control unit, create time programmes for individual days that reoccur weekly, and transfer these to control units.
The app allows you to control the “Off”, “Eco”, and “Comfort” operating states based on the time of day. The Comfort temperature is set using the rotary knob on the room control unit. In the Eco operating state, this temperature is reduced by a value that can be freely selected via the app. In the Off operating state, only frost protection is active, ensuring that the room temperature does not drop below 7 °C.
It is also possible to read out previously imported time programmes from the room control unit and adjust them.
Easy to establish a connection with the EcoTimer app
- Enable location in app authorisations
- Activate the location on your mobile phone after connecting for the first time
- Pair the controller via Bluetooth (switch the controller on/off first)
- Open the app
- Connections
- Switch the controller on/off briefly
- Start a search and select the “Thermostat” displayed
Online calculation tools

Online applications for heating and heat pumps
The right products are the foundation for creating the perfect solution. Choosing them is simple with our calculation tools:
KermiQuickfinder is your simple online calculator for determining heat demand and radiator specifications. The x-net web design application is your practical assistant for calculating panel heating. Here, you can also find an annual COP calculator and a tool for calculating the combined energy label – in other words, the efficiency label for combined systems. For specifically calculating noise immissions from Kermi heat pumps, we recommend our noise calculator – because a feel-good atmosphere is part of creating the right indoor climate.

x-flair power calculator
Our x-flair output calculator provides a quick way of determining the heating or cooling output you need.
For heat pump radiators:
- x-flair Profil
- x-flair Plan
- x-flair Line
NEW: With the x-service app, you can easily perform all calculations and valve settings for the x-flair and all other Kermi radiators from your smartphone.
KermiQuickfinder
The simple online calculator for determining heat demand and radiators.
With the KermiQuickfinder, you can determine the heating load of a room on the basis of house type, room size, and heat source, and then the correct radiator dimensions for the required Kermi product line. Your wish list can then be printed out.
Noise calculator
Noise calculator for calculating noise immissions from Kermi heat pumps during day or night operation on the basis of the German Technical Guidelines for Noise Reduction (TA Lärm) forecasting process.
Annual COP (ACOP) calculator
With the APF calculator, you can calculate the annual COP for Kermi heat pumps in accordance with VDI 4650. The annual COP is the basis on which subsidies are awarded under the various market incentive programmes.

Heating label (ErP labelling)
Online application for calculating the combined energy label according to the ErP guideline.
Background: Since 26 September 2015, all quotations for heat generators and domestic hot water heaters or storage tanks and compound systems must have an energy label according to the EU Ecodesign/Labelling Directive 813/2013 or 814/2013. To generate the efficiency label (packaging label) in the case of compound system quotations, VdZ has developed a heating label web tool. This sector solution contains all the relevant data for Kermi x-change heat pumps and x-buffer storage units. The combined energy label generated by the application can either be downloaded or integrated into the heating engineer software via an interface.
