Welcome. I think you may be mixing up fireplaces with fireplace inserts? Not sure. Are you asking about a woodburning insert to go into the current prefab or a total tearout of the current prefab and replacement with a modern EPA ZC (prefab) fireplace? Post a picture of the current setup so that we can see what you are starting with.
Exactly, it's the terminology I'm missing. I've read through several posts on this site but many involved installing an insert in an existing masonry fireplace. I have a pre-fab standard fireplace that I would like to replace. I don't have floor space for a free-standing stove, so a fireplace is preferred.
This is the only photo I have right now, but I have concrete floors (with radiant heat) and no hearth. The rug is no longer used. There is a similar unit directly above this one on the second floor, but it has a fan to circulate air around the fire box (but it seems to mostly make noise). That unit has a hearth. They share a chimney cavity, but have separate flues, capped by a simple rain cap and screen.
I love high efficiency things (ANY high efficiency devices!), so a good EPA unit is definitely in the cards. Even a masonry heater type of fireplace would be cool (though quite pricey). When I factor in the value of my time and the availability of wood, however, geothermal becomes another option on the table.
Short term, I need a reasonable improvement to the existing setup at a reasonable price. I don't really have a time frame on this, as I want to get a rough plan before talking specifics with my wife. My perception is that a pre-fab fireplace should not have an insert installed INSIDE of it, correct?
Long term, the options are endless (until they aren't, of course), but might include a boiler/WH, outdoor installation or any number of other high-efficiency options. I've got a 3,200 sqft house with basically a east and west wing and no true central family/great room. Current setup uses propane for the radiant heat as well as a 91% eff propane furnace.
Thanks for any additional input.
