It can be used in existing oil boilers with only small alterations, giving heat producers a clear incentive to switch to cleaner fuels.

(2) Where heat produced by materials handling equipment is capable of raising the temperature in any area occupied by an employee on the equipment to 27°C or more, the area shall be protected from the heat by an insulated barrier.

(3) If it is necessary to heat a storage facility, it is recommended that the heat be supplied by an electric heater which complies with section 19 or by low pressure steam, hot water or other enclosed heat transfer media with the heat source located in a detached building at least 10 feet from the storage facility, and heating systems which do not comply with this recommendation shall be approved by the Commission.

The requirements laid down in Council Directive 78/170/EEC of 13 February 1978 on the performance of heat generators for space heating and the production of hot water in new or existing non-industrial buildings and on the insulation of heat and domestic hot-water distribution in new non-industrial buildings[32] have been superseded by provisions of Directive 92/42/EEC, Council Directive 90/396/EEC of 29 June 1990 on the approximation of the laws of the Member States relating to appliances burning gaseous fuels[33] and Directive 2002/91/EC of the European Parliament and of the Council of 16 December 2002 on the energy performance of build ...[+++]ings[34].

In order to avoid distortions of competition, electricity generators may receive free allowances for district heating and cooling and for heating and cooling produced through high-efficiency cogeneration as defined by Directive 2004/8/EC of the European Parliament and of the Council of 11 February 2004 on the promotion of cogeneration based on a useful heat demand in the internal energy market where such heat produced by installations in other sectors would be given free allocations.
