How many litres of heating oil or m3 of NG can you save with M-WRG?
This depends on the building (e.g. on the insulation), on the geographical position of it, quality of the heating device, and on the important factor of user attitude. You can save roughly 30 litres of heating oil or cubic meters of NG per device and year (in conditions similar to German winter). For a typical one-family home with a floor area of 130 m2 this would be app. 150 l or m3 per year.
