All - Looking for some advice as I start to look at both of these models to replace the EP-25 I currently have (too small for our house). I have the P43 at the normal $2899 price, then I have the Advance which is "refurbished" from the dealer with a 1 year warranty for $2500. Thoughts? I see the Advance is rated at a slightly higher BTU (48k) so it might be even better. Anything that would make the Advance less user friendly/serviceable than the P43? Thanks all!
