The formulation of revised quality, design, and safety standards for heating and plumbing installations would be a matter primarily for the National Standards Authority of Ireland, NSAI. The European Communities (Efficiency Requirements for New Hot Water Boilers fired with Liquid or Gaseous Fuels) Regulations 1994 require that new domestic boilers installed on or after 1 August 1994 meet prescribed minimum efficiency requirements. The option of requiring boilers in new dwellings to meet the equivalent of the Sedbuk A or B rating in the United Kingdom and have a minimum efficiency of 86% or more will be considered in the context of the implementation of EU Directive 2002/91/EC of 16 December 2002 on the energy performance of buildings. This directive must be legally transposed by January 2006. If this option is pursued, I understand that it would be open to manufacturers to consider the feasibility of adapting non-condensing boilers to achieve the equivalent of the Sedbuk A or B rating.
