Heatmaster G Series OWB

[Larry1948]

Looking for confidence that this boiler will last.  Particularly worried about cracks in the firebox/water jacket.  Have gone through two Empyre ProFab units, one carbon steel and one SS.  The carbon rotted through and the SS developed multiple cracks.  I welcome input from owners of a G Series that have been in service for several years.

Thanks

No idea about any other brand then a Heatmor. Had it since 2007 and I use it to heat my hot water, might have been down for a month in all the time I have had it.

I have run Heatmaster G7000 3 years to heat house and water.  I will be hooking the second output to the barn I am building. Structurally everything has been fine.  Did have a problem this January.  Proper operation is totally dependent on proper air flow.  I have cleaned it regularly as instructed, weekly ash from bottom gasification chamber, couple weeks when ash builds up in firebox, and annually a full breakdown. But I was not getting the bottom inlet feed ports cleaned 100%.  So over time the bit of ash I was not getting built up and cut inlet air down.  I noticed creosote building up but was not sure what was happening. In a matter of a week the creosote clogged up everything and burned out the fan. My dealer came out right away with a replacement fan and we spent the day stripping the unit down to the bare bones and cleaning it up like new.  It ran like new after that.  I shutdown mid April and spent couple hours going through the entire unit again.  It was not bad at all but I was anxious to see how things looked in preparation for next year.
