Converting my oil boiler to wood pellets.

Euro three pass boilers are much better setup for a pellet conversion, unlike the pin-type boilers that aould take longer to clean and would accumulate ash in more places, but this has already been said.

Ahh I have a multi pass Burnham LE. It looks like a good foot or two of heating surface is lost to ash.

That efficiency number is just from analyzing gases of combustion, right? Won't really give you a effective heat transfer ratio. If you measured you flue temperature over time as ash builds up, you'd probably notice when / if you are losing efficiency from losing heating surface, although its probably negligible, and still cheaper then oil =)

I think you mean cheaper than oil...... =)

Sound like my English Major woman. Your Youre Yar Then than their there. BAH HUM BUG, if I was speaking, you wouldnt wouldn't would'nt would not know the difference!

I think I would. Then and Than should be pronounced differently...... =)
