Hi I am new to this site. Currently I have all electric home and am sick and tiered of paying six to seven hundred dollars a month. After, considering all the other options I have decided to go with pellet insert into my existing fireplace (Brick and Masonary). I mainly want to heat 2 floors of my home each floor is about 1228 Sq.ft. The fire place is on the first floor of my living room. I have no doubt it will have no problem for the first floor but I have some concern about heating the second floor (Since they are supposedly space heater and not designed to heat the whole house). I went to dealer close by my area and the guy there suggested two models of QUADRA-FIRE brand. 1. Mt. Vernon Ae Insert: Up to 52460 BTU/HR Input with 47 lb hopper that heats up to 2900 Sq ft. with a price tag of $5233.00 installed 2. Classic Bay 1200i: up to 47300 BTU/HR Input with 75 lb hopper that heats up to 2600 Sq.ft with a price tag of $3604.00 I would really appreciate very much if you could give some guidance and input on this or any other brand that may be better as far as low maintenance and reliable.
