The term "efficiency level” refers to the ratio of the emitted power of a system to the supplied power. The emitted power is divided by the supplied power to obtain this value. The efficiency level thereby determines the efficiency of a heating system and should ideally be 0%. This would be the optimal implementation because the supplied power would be emitted without losses.

A heating system stands and falls with its efficiency level. We place great value in this and therefore only offer highly efficient systems.
