My Furnace may be unrepairable...what is new?
I have an older Suburban NT-30K ducted propane furnace. I think the firebox is cracked. So, whats new in the world of furnaces? Are there any with higher efficiency?
Forum Discussion
Are you looking for electrical efficiency or LP efficiency? The latter is usually what furnace efficiency refers to when not otherwise specified, but sometimes for RVs the former is equally as important if not more so.
