Q. 10 Means of heating
34. Record the primary heating source as follows:
Mark the box for code 1 when dwellings have heat provided by a central power station, power plant, etc., through hot water distribution points for central heating and domestic hot water, usually to a large number of housing units, with radiators used to transfer the heat to the spaces in the dwelling. Included in this code are the district's heating centers (local heating).
Codes 2, 3or 4 will be marked , depending on the situation, when dwellings are heated by their own domestic system, that is installations for heating built in the buildings (steam, hot water) and a system for passing the thermal energy to all rooms inside the building. Include block heating systems in these codes.
When the domestic heating system uses geothermal water, code 4 (liquid fuel) will be checked.
Codes 5, 6 or 7 will be marked to indicate the type of fuel when stoves are used for heating.
An x mark will be recorded in the box for code when the dwelling uses electrical radiators or any different type of heating (air conditioning, etc.), other than those mentioned above.
When a dwelling has several different heating systems, recorded only the primary heating source.
