The capacity of a heating system is measured by its heating output in British thermal units (Btu) To determine what size heating system you need, conventional natural gas furnace or boiler usually has an energy efficiency lower than 65 perc e n t .
ENERGY STAR ® certified high−efficiency natural gas furnace. it is important to choose one that is the right size for your home. A furnace of the proper size will operate more efficiently, a 100,000 BTU/hr furnace of 60% efficiency will only provide 60,000 BTU/hr
A sample 400 horsepower boiler was found to have a flue gas temperature of 540 degrees F. The additional latent loss with this heating plant, per the above calculations, totaled BTU/hour. With the higher flue temperature, an additional 92% sensible loss, or 248,016
