Would a new furnace reduce my propane bills much?
Inspired by a thread here on propane furnace efficiency, I went to the basement and changed the filter on my propane furnace and tried to find out what kind it is. It is a Day and Night and is 16 years old. But it has no information that I can find saying how efficient it is or how many BTUs or what kind it is. There is another one in my attic I know even less about.
I read that new furnaces are much more efficient. Should I consider a new, more efficient heater? How do I find out how efficient my old ones are?
I'm not rolling in dough, but I want to lower my propane bills and do anything I can to reduce my carbon footprint. I am going to get new weather stripping and possibly put up thick curtains in some rooms. Should I save for new heaters?
