I've always assumed that the creosote is not a problem, it's probably not too different than a "cured" frying pan. But anything resembling ash is definitely a problem since it will pick up moisture and promote corrosion. I just wash my boiler with a garden hose and stiff brush, let it dry and then apply fresh engine oil. It would probably be a good idea to run a 20 watt incandescent bulb or a gun-safe type heater to keep it above dew point at all times spring, summer, and fall.does creosote build up in the fire box hurt anything over time?
I'd definitely oil it to. I oil the chimney and the firebox on my indoor furnace every spring .So I'm getting some good info. Thanks everyone.
Let me know if I'm missing anything, Basically do a good clean out in the spring time to remove all ashes and try to scrap off as much creosote as possible. Keep a small light bulb lit in the fire box through the off season to keep humidity out of it. Keep return water temps as high as possible while running. And, the well known, burn only seasoned wood.
can anyone tell some key points to make sure a OWB will lasts for many years of use?
What is the number one killer of the boiler itself?[/quote]
To buy one.....they all die an early death?????
Whoa, hang on. I think perhaps there was an assumption that you already had an OWB and you were looking for ways to make the best of it. Since you haven't yet committed to getting an OWB this would be the point in the thread where the alternative of an indoor gasifier in an outbuilding is explored, although the P&M BLxxxx units certainly look like an exceptionally good design for an OWB.I was looking into the bl series from P&M. I just want to know everything I can do to keep it alive as long as possible.
My suggestion is to wait until you do have the money rather than regret the decision for many years of excessive wood use. If I may ask, how much is the boiler you currently plan to buy?I did explore that possibility, I looked into the gasifier units. I simply don't have the funds to get a gasifier. That's why the BL from p&m looked like the best option. Seems to be the most efficient of a "conventional" OWB. But this vs that is not the point of this thread.
