This Part of BS 845 describes a concise procedure for conducting thermal performance assessments, using the indirect (losses) procedure, to give results within a tolerance of ± 2 percentage points1) for boilers for steam, hot water or high temperature heat transfer fluids and for presenting the results in tabular form. Test results are based on either the gross or the net calorific value of the fuel.
This concise procedure provides a convenient means for assessing boilers which are thermodynamically simple, i.e. having a single major source of heat input and a simple circuit for water, steam or high temperature heat transfer fluid, and that do not condense moisture out of the flue gases.
