Boiler efficiency for community heating in SAP

100% and η 30% are the certified boiler test efficiencies at full and part load expressed in percentages of the gross calorific value of the fuel. Prior to the calculating the SEDBUK, the efficiencies at full and part load are capped (if necessary) to prevent unrealistically high test values being used.

What is ErP? Boiler Efficiency Explained | Boiler Guide

The newer ErP ratings are calculated slightly differently to the older SEDBUK ratings; the result is that boiler efficiencies appear lower under the ErP system. In addition, modern condensing boilers are now required by law to meet a minimum efficiency of 92% so most new boilers will meet this standard.
