I now live in Denmark and I can say that the pellet boilers are very very common here, we have one it's about 7 years old and gives no trouble whatsoever, it's a Woody. (what a name) what type of delivery system does yours have? ours is a screw feed from an old oil barrel, you can have a hopper with it which it then can weigh and tell you how long you have left to burn (it's fully remote controllable but we don't use that function) but it's still fed by the screw system, it doesn't care about dust and we normally sit around 80% humidity it doesn't seem to care about that either. This house also still has it's old oil boiler but we're not using that (you know exactly why!) Our old house has an old wood fired boiler running the central heating, works fine, nothing much to break (thermostat and automatic air control were already broken!) but if you're not home the house is cold! I much prefer the pellet furnace for ease of use, fill it once a day (less with a larger hopper of course) and empty it once every couple of weeks.
One last comment to steve here, check your manual our pellet boiler can burn normal firewood obviously not automatically! it can also burn grains but grains produce more ash than pellets so it needs emptying more often.
