My gasser has been running since last March, not quite a year. I have done myself a huge faver by up grading. Its so nice to go into the boiler room and not have any dust, soot, smoke, etc. like I had before. I can breathe. Not only that, but I'm looking out at my wood pile and seeing more wood left at this time than ever before. I see improvements in plumbing and controls that I want to do after the burn season, only hoping that next year will be even better. Happy New Year !
