I've had the 6000 job for a couple of seasons. It works fine. My burn times are all over the place, depending on the wood and temps out side. I burn junk, rotted and dead wood. Mostly dead, rotted cherry and dead, rotted poplar. I have a lot of it. That stuff burns quick, like about 8 hour quick. At about 0 to 10 degrees outside. Now dead and rotted oak, beach and locust, which I don't have a lot of, the burn time seems to be about 12-15 hour per load. My loads seem to take up about 60-75% of the firebox. What I do not like about my boiler: The paint lob on mine is crappy. Like some spots with a complete lack of paint. So I touched it up. Wiring is a joke, but very simple. I built a shed around mine, which I planned from the get-go , to keep the boiler and log splitter out of the weather. But as I said, it works ok. The damper flapper door needs to be lubed with WD40 from time to time, about once every 2-3 weeks, so that it does not hang open a fraction of an inch. If it hangs open a bit, it'll run hot. One fellow on here, mremm, has a Ridgewood stove but has had some trouble with his running hot. I don't know if his ever got sorted out. Oh well, good luck
