The new owners of AHS probably didn't know about this explosion issue before they bought Jeff's business. The new owners do now offer boilers that are safety certified, and that is why there is a tombstone cover over the inspection port where the explosions exhaust. That being said, and the fact that this is a problem with coal boilers and stoves overall, the new owners of AHS should help to offer a solution and or recall if they have solved the explosion problem.
All this being said, I am happy with the AHS 130 as a replacement for my expensive oil guzzling Columbia boiler. I have saved thousands of dollars since switching. I do want to have peace of mind that the boiler isn't going to puff back when I'm not home or sleeping in bed and cause a fire or detach a smoke pipe and cause a CO leak.
I have had some minor explosions these past three weeks since I've made the following changes:
1. Wired the ash grate motor to dump only when the fan is running
2. Lowered the thermo grate dump temperature to 110
There has been an improvement with the boiler performance and there are few unburnt coals in the ash pan. I agree with Yanche that a slower running fan motor after burn would help with the explosion problem. I feel there needs to be a combination of changes including the ones I have done to eliminate the frequency of the explosions.
I want to thank everyone who has been involved with this thread. We are working to find a safe solution without assistance from AHS.
