Commercial Boilers | Products - Energy Star

ENERGY STAR certified commercial boilers have a thermal efficiency of ≥ 94.0% and a turndown ratio of 5:1. Thermal efficiency is the ratio of the heat energy (Btu/hr) absorbed by the water to the heat energy available in the fuel burned. The turndown ratio is the boiler's maximum nameplate firing rate (Btu/hr) divided by its lowest nameplate firing rate (Btu/hr).

Boiler Efficiency: Which Boilers Are Most Energy Efficient?

Condensing boilers are the most energy efficient, typically being 25% more efficient than non-condensing models. If you still have a old-style non-condensing boiler, then replacing it with a new condensing boiler could save you £45 to £300 a year (Energy Savings Trust, 2021). All modern boilers that you can buy are condensing boilers and have
