Explanation:
Because some of the heat produced by a condensing oil furnace is latent heat, it functions more efficiently.
<h3>Is the capacity of an oil furnace expressed in input or output?</h3>
The steady-state heat output of the furnace, expressed in BTU/h, is known as the heating (bonnet) capacity of oil heating appliances. Today's typical oil-fired central heating units for residential use have heating capacity ranging from 56,000 to 150,000 BTU/h.
<h3>What unit of heat is the capacity of an oil furnace stated in?</h3>
The amount of heat (Btu per gallon) released during the combustion process, in which the oxygen from the air combines with the hydrogen and carbon in the fuel, is how a fuel oil's heat of combustion value is expressed.
