I use Hamer's and I'm plenty happy with the performance. Could it be a feed rate problem? It took me 1/2 the season last year to adjust the feed rate correctly. I can run my stove for 8-10 hours and get maybe a 1/2 cup of ash out of the firepot.
Its not a feed problem, it might be a flue problem. After my post yesterday the stove ran for 24 hours straight no problems. This morning turned it off the do a quick cleaning, was burning Hamer's pellets since yesterday. I use a paint brush to brush down the back wall and the logs and brush the ash into the ash bin under the firepot, about once a week I vaccum good. Today after turning it back on after the cleaning it starts firing up and just as it is hot enough to go out of the startup cycle it cuts out. I wait for it to shutdown and then I disconnect, the airflow hose from the backwall to the airflow switch and blow it out and start it backup, and it was stillling running when I left for work this afternoon about 45 minutes of running time.
Im avoiding calling for service, cause last year when I checked once at the store in Wadorf where I purchased it they wanted a arm and leg, think it was $90 for the first 30 minutes and I cant remember what they said after that. They really have sort of a monopoly, since not too many places sell them.
Fox5 had just a short thing on the news the other night about pellet stoves and how they are becoming popular, the guy was in Waldorf at American Hardware, I got my stove at the other place in Waldorf, they said that pellet stoves are out selling wood stoves 3 to 1.
When my stove is running it heats
the whole house my oil furnace never comes on, I have a splitfoyer home 46x26. It does a great job.
