Hello all, I've been lurking for a few weeks and have found some great info...between this site and woodheat.org, I think my learning curve will be substantially shortened! But, I'm still clueless. I've done a bunch of research and my wife and I've visited several local shops to check out wood inserts from Jotul, Lopi, Enviro, Regency/Hampton, Napolean, and PE. Between clearances and style, we're left deciding between the Enviro Venice 1200 and the Hampton HI300. Sadly, the Enviro 1700 is a 1/2" too deep for our fireplace, and I'm concerned about the (small) size of the 1200. Here is the skinny: our colonial house is laid out as shown below (built in 2002). 2,000 sqft total, with 256 of that being a bump-out room with 11 foot ceilings where we spend most of our time (room has a five foot opening to kitchen and rest of house). That room has a ceiling fan installed. We currently heat with an oil furnace and are looking to make as big of a dent in that bill as possible...without overheating the bump-out room. Bottom line, we like the styling of the Enviro 1200 best, but the Regency seems to be a better fit size-wise. Problem with the Regency is that the surround almost exactly mimics the style of our mantle...so it looks a little tacky and the selling shop told us a custom surround was essentially out of the question permit-wise. So, the questions to the gurus: Is the Enviro big enough or should I only be thinking about the Regency? Will the the Enviro be able to pull an overnight burn? Considering the size of the Enviro firebox, I'm surprised they claim the numbers they do. Here are the stats on the stoves: Enviro 1200 Venice: Firebox: 1.85 cubic feet Output: 67,000 BTU Claimed heating area: up to 2,200 sqft Efficiency: 83% Regency 2400: Firebox: 2.30 cubic feet Output: 75,000 BTU Claimed heating area: 2,000 sqft Efficiency: 77% Thanks for any help and advice! Lou Edited: Not considering the Regency 2400, it was meant to say Hampton HI300.
