(7) The predominant type of heating is that which heats the majority of the rooms. "Long-distance heating" should not only be the response concerning supply from a "long-distance heating plant", but also in the case when a "block heating system" supplies multiple buildings of an apartment complex with heat. "Other heating" is chosen for a solar heating system, for example.
(9) This question is only to be answered by those with oven heating (single ovens), dwelling central heating (level heating) and house central heating in buildings with one or more dwelling. With regards to house central heating in a larger building and long-distance heating, it is to be supposed as a rule, namely that the dwelling occupant/ owner does not know the type of heating fuel.
(10) Here every heating fuel should be noted that--as long as it is technically possible--the chosen heating from Question 7 appears on the first line in consideration, if in the case the chosen ordinarily used heating fuel in Question 9 is not available (i.e. transposition to a coke [Koks] heating due to oil deficiency).
