Are gas furnaces efficient?
Hereof, are new gas furnaces more efficient?
And New Furnaces Are Indeed Much More Efficient The measure of furnace efficiency is AFUE (annual fuel utilization efficiency), which is the percentage of natural gas the furnace converts into heating power. New furnaces, however, can have AFUEs from 80% all the way to 98.5%.
Herein, is it cheaper to heat your house with gas or electric?
Less expensive to operate: Almost everywhere in the country, natural gas is significantly cheaper than electricity. Faster heating: Gas heat tends to heat up the home faster than electric heat because the gas furnace produces maximum heat as soon as the burners start running.
A furnace with an AFUE rating of 95% will require significantly less fuel (natural gas) to heat your home than a unit with an 80% AFUE rating. While higher-efficiency furnaces tend to cost more upfront, they allow homeowners to save money on heating costs every year.
