Hi everyone. I'm trying to choose my outdoor boiler (how many times have you read this?). I've searched the archives, and I'm trying not to be redundant. I like the Aqua Therm unsheltered 275. The closed system seems to make sense. Less corrosion, no heat exchange plate to connect to oil boiler, less water to heat up. Does anyone have first hand experience with a closed system? I find it hard to believe some of the stories/rumors? My neighbor is very happy with his CB. He just bought his second in 10 years. He has had 3 leaks over the years, got them welded, but replaced it after the third. I have to stress that he recomends the CB, but I don't like the corrosion issue. Maybe the 409 stainless and closed system would prevent holes. On the warranty from CB, the factory said to send it back, and they will assess/ repair the leak. Not a viable option. I also like the auger on the Aqua Therm, as opposed to shovel system. Any thoughts?
