In my area, there are two choices for wood stove installation- one, a chimney sweep business; the other, a heating company hired to install stoves for Hearth and Patio (Osburn, Vermont Castings, Jotul). I recently got estimates from both. Still deciding about stoves. Both companies say they will install any stove I pick, but it must be EPA certified (for homeowner's insurance). The chimney business sells Pacific Energy, and recommended the Vista LE, but when he called with the estimate, he said there is a problem with the Vista LE EPA certification- something having to do with the fact that it is in Canada- and that he can only install the Summit LE, which is far too large for my needs. I was driving at the time, and could not give him my full attention. I have called back for clarification, but was late on Friday, so will wait until next week to ask questions. Any idea what this might be?
