Hey everybody, first a little background. I live in Southwest Va. in a doublewide, or mobile home, or whatever you want to call it. It is 28' by 56' with three bedrooms. The floorplan has the kitchen, living room and dining room open. The existing pre-fab fireplace is in the living room. Last year I wanted to buy an insert but couldn't talk the wife into it, although I did talk her into taking the gas logs out and burning wood in the fireplace. This didn't do well at all. Had to keep the fire roaring to feel anything at all. Well she went up to her brothers for a birtday party and saw his freestanding Buck stove. After all the questions to him it seems their electricity bill went from 280.00 to 60.00 . Now I have her on board for an insert, tried to talk her into letting me tear out the fireplace and put in a freestanding unit but the best I could do was an insert. I sent an e-mail to Buck and they recommended a Model 18 insert. I'll have measurements later but it seems so small. Any other inserts that will fit the bill besides the Buck? Oh yeah they recommended the Buck because it was approved for a prefab fireplace and a mobile home. As far as the pipes they are double walled Iknow I'll have to get home and dig out the paperwork to see more info on them. Usually this being such a rural area Buck is the standard. Just wondering on more options?
