Our 2 Heat Pumps - MS's have been used , part of the time , the last week or so . I try to turn them off & turn the gas furnace central system when the OAT drops to 25 or less .
The furnace is 15 - 20 years old , but 90% or 92% 2 stage condensing unit . It runs on low flme 99% of the time .
But then I am paying to heat just about 100% of the house .
God bless
