Classification of domestic gas boilers based on efficiency

Abstract

Methodology for calculation of Seasonal Efficiency of Comestic Gas Boilers is set by the UK Government's Standard Assessment Procedure for Energy Rating of Dwellings. This methodology is general applicable, and can be applied in our country. This methodology is compatible with EU Council Directive 92/42/EEC on efficiency requirements for new hot-water boilers fired with liquid or gaseous fuels. Thus calculated Seasonal Efficiency is relevant parameter for comparisons of different models of boilers. Energy Efficiency Bands are as signed, in a first place based on verified values of seasonal efficiency. In correlation with seasonal efficiency stands annual fuel consumption of certain boiler, and consequently annual fuel consumption of certain boiler, and consequently annual fuel costs are comparable.
