cool, glad it came apart. nothing worse than stuck parts.

the efm i had was in a shed for 20 plus yrs in pieces before it was given to me and my friend.....everything was seized on that stoker mechanism.....scrapper and i never did get the pot apart, the whole stoker had to be taken to him when it needed work.

I hear that!
I repair commercial pressure washers. A hollow shaft pump coupled to an electric motor will NEVER come apart if assembled dry when some poor slob like me tries to separate them after 5-10 years. I've bent motor shafts and destroyed pumps trying to get them apart.
Just a nice coat of anti-seize and they separate after a little coaxing.

Anti-seize is not an option around this place with trucks and PA road salt and calcium in the Winter... it is a religion.

I have been forever trying to pound it into thick heads all around me that an additional 30 seconds it takes to slobber that stuff on the threads will one day save you 30 minutes or much more of swearing, heating, pounding and still snapping the fastener off anyway. I like to slather it all over the inside of those auger pipe couplers and I have never had any problems getting them to slide off.

To me, 9 years was a really good run for that pipe running in damp coal. I get about 5 at the most on the 1300.

Agreed, it's become my best friend here too.
I try to limit the amount of water on the coal, but sometimes it can't be avoided. A few times in the winter it was frozen in the trailer and I had to thaw it with hot water.

how well did the efm 350 do with the water to air heat exchanger?
i know it's not ideal but it will take some time and money to convert from forced air to hydronic.

i thought my basement was tight until i read the first few pages of this thread.
i got a decent amount of room but only 6' to the floor joists. i'll be able to put the efm 350 30" from the wall and 30" from the oil furnace. i do need to move the hot water heater tho.

The EFM works very well feeding the heat exchanger.
