Question 4.1 (more than one answer is possible)
A centralized system refers to a system that heats all the apartments in the same building, but is located outside the premises like, for example in one of the service areas of the building (cellar, basement, etc.). A system connected to a remote city heating system is also considered centralized.
A fixed independent system refers to a system that heats a single house and is normally located inside or nearby the house (for example, the boiler could be located in a special internal area or on the balcony/terrace; solar panels could be located on the roof, and so forth), and is independently operated.
A fixed individual system refers to a system that is not connected to the centralized system or regular independent system, and which cannot be moved like, for example, fireplaces, individual gas heaters, heat pumps, electrical plates, coal, kerosene, wood and LPG (liquefied petroleum gas) heaters.
If there is no heating system, or there are mobile heaters like electric, gas or other types, place a cross in box 5 ("Does not have ...").
