Hello dear house-building friends,
we are more or less about to build (have built) our house.
Our trade partner in the field of "energy technology" made a change to the ventilation system after we asked for a better offer during the negotiations.
Previously, he had offered the Alpha InnoTec LG 317 TB with the duct system type DEWI-AIR 75, now it is supposed to be the ventilation unit with heat recovery Vallox Controlled Residential Ventilation 090SC.
I cannot judge the difference except that the systems were offered as follows:
Alpha InnoTec LG 317 TB (€11,697 gross)
Vallox Controlled Residential Ventilation 090SC (€8,865 gross)
The price difference is obvious... but that’s not everything, right?.... Can someone explain the differences or give a recommendation/justification for one or the other variant?
I look forward to help/feedback and say thank you!
