This document is applicable to gas-fired appliances producing domestic hot water. It applies to both instantaneous and storage tank appliances; waters-heaters and combination boilers that have:<\/p>\n

    \n
  1. \n

    a heat input not exceeding 400 kW; and<\/p>\n<\/li>\n

  2. \n

    a hot water storage tank capacity (if any) not exceeding 2000 l.<\/p>\n<\/li>\n<\/ol>\n

    In the case of combination boilers, with or without storage tank, domestic hot water production is integrated or coupled, the whole being marketed as a single unit.<\/p>\n

    The water heaters covered by the present document are considered \u201cconventional water heaters\u201d as defined by the Transitional Methods (Commission Communication 2014\/C 207\/03) then in the calculation formula for the Annual Electricity Consumption (AEC), Qcor<\/sub> is equal to zero.<\/p>\n

    EN 13203\u20111<\/span><\/span> sets out in qualitative and quantitative terms the performance in delivery of domestic hot water for a selected variety of uses. It also gives a system for presenting the information to the user. The present document sets out a method for assessing the energy performance of the appliances. It defines a number of daily load profiles for each domestic hot water use, kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of different gas-fired appliances to be compared and matched to the needs of the user. Where other technologies are combined with a gas-fired boiler or a water heater to produce domestic hot water, specific parts of EN 13203<\/span><\/span> apply.<\/p>\n
