Details

This report reviews the first complete year’s data from field trials of 60 condensing boilers carried out on behalf of the Energy Saving Trust.

The trials had four stated goals:

  • to evaluate the in-situ performance and efficiency of combination (combi) and regular condensing gas boilers;

  • to compare measured efficiencies to the SEDBUK database;

  • to determine the amount of space heating supplied by secondary systems;

  • to compare results to BREDEM/SAP assumptions and Part L requirements and; to provide suggestions as to how BREDEM/SAP might be updated to take account of the trial results.
