The yield (%) is the ratio between the actual efficiency and the maximum theoretical efficiency expected from the boiler.

It is automatically reached by the transformation of the electrical energy into heat energy, a stabilized nominal power which limits the energy consumption to the very minimum, without unnecessary energy consumption.

The boiler « Mini Europe » is among the best in the market, resulting from the low loss of its circuit thanks to the quality insulation of its hydraulic components. See our comparison below.

From electric energy to heating energy

Cold water arrives through the low point of the boiler, its temperature increases during its crossing due to the contact between the electric heating body and the high point. When it reaches the required temperature, the boiler switches off and then re-engages if the temperature drops.
