ZC Fireplace if price wasn't a concern?

If price is no concern, what ZC fireplace would you choose to heat a house 2800 sq ft? FPX44? Quadra Fire 7100? Z42? BIS? Another....?

FPX 36 Elite (or the new 36-CVT) or Heat N' Glo North Star (essentially the same as the Quad 7100, but cheaper) would be my recommendation- FPX 44 might be a bit large, depending on your set up.

That CVT is intriguing, thanks for posting.

Price wasn't my concern either...

I use the 44 elite to heat 4200 sqft and it does the job down to -10. It then is a challage to keep a few of the bedrooms above 70

How large a ZC fireplace you need really depends on where your house is located (climate), the ceiling heights, the amount of insulation, the layout of your house and several other factors to determine BTU's needed. With that said, I would recommend the FPX 44 Elite as a great heater and don't think it would be too large for 2800 sq ft in a house with an open floor plan so heat can get to most parts of the house..

RSF models, without a doubt.
ZC's are their specialty, and they have made it into a science.
But, they are expensive & require their brand of chimney, I believe.

my kozyheat z42 has been really good to us. It heats our home 3700sf . Doesn't eat alot of wood either. Good over night burns - easy to operate. Love it.
