Newbie to the site here and looking for advise / opinions on my current fireplace setup. I have a Martin LF36B fireplace in my house that I use multiple times a week but would like to get more heat out of it as most of the heat goes right up the chimney. I looked into putting a wood inset in and I was told at my local energy shop that the Lopi Answer insert is about the only one that would fit into the current Martin. The Answer sure is small but seems to get good reviews online. My house is 1500 SF ranch. Looking for opinions as to whether the Lopi Answer insert would give me enough heat to heat the house or if anyone knows of a different insert that might work. I can get the Lopi installed with liner for around 5K. Pic is current Martin setup. Thanks.
