Domestic boiler. There is only one norm concerning energy efficiency of boilers. This standard is defined by the Directive 92/42/CEE, which is applied in all European countries. Manufacturers respect the European Directive boiler, but only a few of them have accepted the stars label systems. This labelling is voluntary. But the different levels of star on the label seem to be poorly adapted to permit an indisputable placing after laboratory tests. The regulation applied in every European countries, for the boiler is the EU Directive 92/42/EEC which states: ”This Directive, which comes under the SAVE programme concerning the promotion of energy efficiency in the Community, determines the efficiency requirements applicable to new hot-water boilers fired by liquid or gaseous fuels with a rated output of no less than 4 kW and no more than 400 kW, hereinafter called 'boilers'”2. This regulation, which enforced a minimum efficiency, has not imposed high efficiency boilers on the market. The impact of the regulation has been to confirm what was already available on the market without giving a real impulse to the best products. Also, some countries have put in place regulation to replace boilers before failure or install efficient products. This is the case of Germany, where in general, new installed boilers have to be low-temperature boilers or condensing boilers. This is required by energy saving laws (Heizungsanlagenverordnung). Another Decree concerns the replacement before failure of existing boilers according to their heat losses. This Decree on small boiler (Kleinfeuerungsanlagenverordnung) defines deadlines for replacement of existing boilers3: Nominal power of boilers Exceeding of permitted losses by 100 kW Deadline for replacement > 100 kW 3 % or more 1/11/2001 1/11/1999 2 % 1/11/2002 1/11/2002 1 % 1/11/2004 1/11/2004 In other countries, there is no obligation to replace the boiler before failure.
