How many M-WRG ventilation devices does a one-family house need?
The number of units depends on the number and dimensions of the rooms which will be equipped with M-WRG. In individual cases the layout can be done by us if we are provided with necessary data (house type, area of habitable rooms, floor plans, profiles, elevations, insulation certificate). However, you can calculate roughly as follows: Per 20 to 30 m2 of floor area one M-WRG unit. (The desired use is also very important, as in living room vs. bedroom in respect to the noise level of the device.) A typical one family home will need at least 4-6 devices.
