Just found this forum and decided to join.
My two story colonial in central MA, purchased 20 years ago, came with an Alaska stoker II in the basement. The stove had with a hot air jacket that provided forced hot air to the above floors, a water heat coil that supplemented the electric water heater, an thermostat controller, and a back-up DC motor that could be used to replace the AC motor in the event of power outage. The set-up worked great but, for the past couple of years, I had to constantly tinker with the stove to keep it running. First to go was the built in blower fan on top of the coal bin, then the booster fan in the duct work went, and finally one of the two HVAC blowers for the hot air jacket died. On top of that I had to replace the feed motor after 18 years of reliable service but the replacement needed constant lubrication to keep it going. When I first moved into the house, I would start the first fire in the fall and the stove would burn all winter. For the past two years I had to restart the stove 1/2 dozen times per season.
So, I finally broke down and got a new Stoker II. So far I could not be happier but I no longer have DC back-up. The old stove would run for a week on on 12 volt battery but I no longer have that option. Attached are pics of the old and new stove. Any suggestions for back up power?
