I've looked at Keystoker Hearth models at my local Keystoker dealer. My dealer stated the Hearth model is basically a reconfigured 105K---assuming 'yer familiar with Keystoker's stove designs... The only negative I could see was the limited coal hopper capacity---it can't hold much more than 80-100 lbs. That means the unit it wll require close attention on colds days when burning hard.
I'm still considering one of these units; however, you'll have to pay attention to prevent running out of coal. Hey! I'm lazy!! I'm accustomed to letting my Keystoker Koker (6 bag/240 lb hopper) go 24 hours between adding coal and dumping ashes...
