Electric Boiler Efficiency Explained | Boiler Guide

Comparing the efficiency of electric, gas and oil boilers side-by-side can be challenging because despite being 99- efficient, electric boilers tend to have an ErP rating of D. On the other hand, all condensing gas and oil boilers must reach a minimum efficiency level of 92%, yet this is enough to award them an ErP A-rating.
