Division 2 PACKAGES OF A SOLID FUEL BOILER, SUPPLEMENTARY HEATERS, TEMPERATURE CONTROLS AND SOLAR DEVICES

United Kingdom

Original text. Later amendments are not shown.

The fiche for packages of a solid fuel boiler, supplementary heaters, temperature controls and solar devices shall contain the information set out in Figure 1 or Figure 2, as appropriate, for evaluating the energy efficiency index of the package offered, including the following information:

(a) I

  • the value of the energy efficiency index of the primary solid fuel boiler;

    • (b) II

  • the factor for weighting the heat output of primary solid fuel boiler and supplementary heaters of a package as set out in Tables 2 and 3 of this Annex, as appropriate;

    • (c) III

  • the value of the mathematical expression: 294/(11 · Pr), whereby Pr refers to the primary solid fuel boiler;

    • (d) IV

  • the value of the mathematical expression 115/(11 · Pr), whereby Pr refers to the primary solid fuel boiler.
