Yes, hopefully he doesn't have any more problems.
Does he have the 7300 or the 7300E?

7300 coal version. I think my friend would have been way better of with efm520 and his set up would take very little to close in and insulate.

I couldn't find anything on a coal version. I did find this video from 2013. If his pan is as shallow as that one, it's possible that he may need to empty it twice a day with coal.

Its too bad they(the water stove builder) don't just wake up and build an underfed coal stoker with a shell and tube 3 pass heat exchanger just like the steam locomotives that used auger stokers that simply dumped the coal on a coal grate with underfed combustion air to burn it.

An EFM underfed stoker or a flat grate stoker would work well with a 3 pass shell and tube heat heat exchanger to make hot water while using a second forced draft fan to pull the flue gasses through the three sets of tubes to pull all the heat out of the flue gasses. :(

My friend heard back from the manufacturer. They are concerned that it's a bad casting and wonder how many more sets will be an issue. They do not expect that kind of damage in 6weeks of use even if the ashes were left in the boiler.

Their concern is with their supplier changing material used.

They do know that a coal bed temps exceed the melting point of...
Even 'good Cast Iron'...
When you let the ashes build up to the base of the grates...

I don't think the manufacturer knows that. I also don't think they realize what happens when you get an ashpan that is very near full, and you add a blower to the system that is superheating that coal and turning it into a forge.......especially if any of that hot coal is falling into the almost full ashpan.

Clearly... :wtf:
A sharper pic would also help...
The failure looks like a thermite torch was used... :blowup:

I too agree that with such a small ash pan more frequent emptying is essential to grate life.

24 hr shakedown and no different than normal. I did this myself so there is no question about how long or how much. I put a $20 there for sizing. Plenty of room for ashes. There is a clinker and hopefully not part of new grates?

Ash amounts are going to vary greatly with the outside temperature. When it gets extremely cold out like we had a week ago, the ash amount will rise dramatically. Keep a close eye on it, and empty the ashes often.
