3.3.7 Question 9: Central heating
a) They say that one shared building has one shared installation of central heating when it is supplied, for the most part from its dwellings, by one single source of heat (one furnace for example) ; are equally considered as such the buildings using "integrated electric heating" or "central heating by hot air heating."
- Concerning the source of shared heat, it can be:
- either right to the building: in this case, check box 3 ;
- or shared among a group of buildings (generally neighboring buildings): in this case, check box 2 ;
- or shared among an important number of buildings dispersed on common territory and dependent on a communal institution or shared between districts (urban heating): in this case, check box 1.
- check box 4 in ALL other cases, even if it concerns a shared apartment building in which most of the dwellings have installations of individual central heating.
b) If you have checked boxes 2 or 3 of the main question, do not forget to specify the fuel used.
