Making a furnace more efficient?
Question:My brother has an oil burning hot water baseboard furnace. What are some ways to make it mor efficient? The heating bills last winter were out of control and it really wasent even that cold also he only keep its about 68 degrees in his house. Im helping him out with it because i know more about HVAC then he does. So far ive rebuilt the furnace, new gaskets, fuel enjector, new water pump, mostly all new copper pipes (insulated), new expansion tank and a couple other things i cant think of. What else can i do? The bill is incrediably high. The house is about 2500sq feet. Also the furnace says its only 9% effeciant. Any help would be great!!
Answers:
If the furnace has only 9% efficiency, replace it. Current furnaces are at least 80% efficient, some claim as high as 94%, but his is in a controlled laboratory. They gain efficiency by running the flue gases through more turns to extract as much heat from the burned fuel prior to exhausting. The gases have so much heat extracted that the waste condenses into liquid water and CO2 gas.
Newer oil burners can also burn bio-diesel fuel.
Truth is if the furnace is less than 70% it is not even worth the effort. just get a newer one .. ... that is the wisest use of your money & effort.
