On domestic appliances such as refrigerators or washing machines, we are familiar with them: the EU energy labels. With the aim of keeping energy consumption as low as possible, we as consumers pay attention to the energy efficiency class of the device - it really should be A or higher.
If you look and the use of energy in private households more precisely, you can see that more that two thirds of the total energy demand is required for heating rooms and domestic hot water. There is therefore huge savings potential in our heating.
With the cutoff date of September 26, 2015, according to the EU standardised eco-design/ErP guidelines, specific minimum requirements also apply for heat sources, domestic water heaters, and combined systems.
These new minimum requirements with regards to energy efficiency, sound power level, and heat retention losses need to be met by the following products:
The following must be labelled with the EU energy label:
Why you are on the safe side with Kermi:
All system elements in the "Kermi x-optimised heating system" which the guidelines apply to, such as the x-change heat pumps and x-buffer heat storage, meet these new requirements or in most cases, far exceed them.
You get the green light when it comes to energy efficiency for Kermi x-change heat pumps.

Domestic hot water
The product label shows the efficiency class for the respective heat source. Efficiency is divided into classes from A++ to G. The Kermi x-change heat pumps are all in efficiency class A or higher.
The combination label marks a combination of a room heater with various expansions available to the end user. Thus for example, the combination of an x-change heat pump with an x-center controller is given a combination label. So with a balanced system, such as the Kermi x-optimised heating system - the energy efficiency can additionally be increased.
