Hi, I am new to the forum and have read a lot of information over the internet about fireplace inserts... I'm sooooooooooo confused. I've just now stumbled onto this forum and read some of the posts regarding selecting a wood burning insert. I'm still at a loss how to tackle this... My biggest challenge is that I am a renter. The house is currently heated from an old heating oil furnace that is costing us a bundle and it hasn't even gotten cold yet. Last year the first time we had to fill the tank was just after moving into the place (100 gallons - it just about did us in) and then the reality of our mistake sunk in. Problem number two, we still don't have much in our budget. The third thing that I am concerned about is I do not feel good about our landlords abilities to have anything to do with choosing one or the installation of something that may be acquired for the purpose of keeping us warm. Other than his permission! This is a 3br - 2 & 1/2 bath with a loft that has a vaulted ceiling over LR. The windows are single pane, aluminum sash, and I can't even reach two of them so using plastic will only help so much. I'm attempting to find a viable way to keep from running the forced air furnace so much as the electricity to power it and the cost of the heating oil combine to be astronomical. Help... I haven't even talked to the landlord yet because I want to be well informed first. There is a masonry fireplace, that measures about 36" wide X 27" high X 42" deep (of that 18" is the depth of the hearth). The top of the fireplace is arched and the box (of course) tapers inside so measurements of an insert will need to take into account these variables. Is it even worth looking into getting an insert- - -it might need to be a cheap or free one- - -is that safe?
