My house has two heat pumps. They work well most of time time, but when the temperature drops below 32, they're not so
good. I have a wall-mounted propane heater on the wall in my bedroom. We never run it when we're asleep. It is only used
for supplemental heat during the evening before bedtime.
I'd like to have a wall-mounted vented heater that can be run while we're asleep. Since the only place to mount it is on
an inside wall, how are these heaters vented? Do they require a hose being run from a port on the heater to the outside
of the house? The attic is just a few feet above the heater. It would not be that hard to run some sort of vent through
the inside wall and into the unfloored attic space.
What brands or models can you recommend for a bedroom?
