I grew up with a wood stove. I wondered if adding a stove to my house would help out with my propane cost in the winter. I have als heard that some of these can heat your hot water. I would love an outdoor unit but they are out of my proce range. I have a pre fab type fireplace but no massonary chimnay. WOuld it be possible to mount a stove flush in this spot? I know I will have to replace my current chimney pipe with class A chimney. Can I do this from the top, pulling the old pipe up and out and installing the new that way? Is there a way to mount a stove in my current openign flush after taking the insert out and making it look and work right? (AAnd be safe). Would there be a way to distrubute the heat from the stove to the back end of the house where the bedrooms are? Maybe installing another return register in the living room and running the central air unit's fan? I appreciate any advice and help. Here is a copy of a video of my current set up.
