Description The e2 models work according to the principle of the regenerative heat exchanger. The storage brick sits in the middle of an air flow of an EC axial fan. Thanks to a reversing air flow generated by a targeted directional change of the fan, the ceramic becomes charged with heat energy from the ambient air and emits it into the outside air. This works so efficiently that 96% of the heat energy in the air is recovered. The combination of e² and ego ensures hundred percent ventilation with heat recovery throughout the entire house, and is ideal for KFW houses.
