Ash in Boiler

Post by rlangley » Sun Jan 21, 2018 5:34 pm

Hi, New to this forum. I installed a Portage & Main 28-40 OWB this fall and am wondering at what depth the ash impairs the performance of the Boiler. I rake the coals at least once a day to try and push some of the ash to the ash tray but I have noticed that the depth is now about 3 inches. Has anyone done any experiments to see conclusively if keeping the firebox clear of ash all the time produces better performance?

Hi rlangley welcome to the site. I have never had a PM but have heard good things about them. I am sure someone will stop by and answer your question in a bit.

I have not had a P&M either but all the different stoves I have used worked better with some ash built up.
Stirring the ash to bring moisture to the surface it a good idea.

Hopefully someone that has run a P&M stove will reply.

I usually rake my coals whenever I load and auger them out then. I usually have that much around the edges of my grating through out the season. Probably has some impact but not enough for me to worry about as long as you clean it all out when you shut her down.
