Question 7- What is the main type of heating available in this dwelling?
[There is an image of box for question 7]
In case there is more than one type of heating device used you should choose the one that is most frequently used.
Consider central heating as a system that diffuses or distributes heat by means of a network of hot water pipes or hot air, produced by centralized heater (air conditioner, boiler, heat exchange, heat pump, etc.).
The heat recuperator can be considered as central heating or non-central heating, depending on whether or not it is connected to a system of hot-air distribution. Hence, for a heat recuperator that is installed in a fireplace, not connected to a hot-air distribution system you must choose the option "Heat Recuperator". In cases where the heat recuperator is connected to a hot-air distribution system it must be considered as central heating.
The air conditioner can also be considered as central heating or not (as mobile or fixed units).
[If the option is "none", go to question 9]
