I need some suggestions for heating my parent's home. They have happily heated with 2 stoves, one in the basement 1 upstairs
for many years but it's getting to be too physical for them. Other family members want to stick in an unvented propane burner
upstairs and down. Yikes! There is currently no central anything so no ducting exists but it would be relatively easy [full open basement]
to have ducting. I'm currently thinking a propane furnace but don't know much about them [ no natural gas available] and haven't
seen any installed without forced air/ducting since the end of the paleo era.
Thoughtful suggestions and questions encouraged I just got blindsided with this problem and it isn't something I know much
about. Thanks in advance.
