Thanks for the referral on the sensa-phone. I'd not lose any sleep about your K-6 failing. Bulletproof except for a direct hit with a nuke. I like the friends visiting daily approach......so will Felix the cat. Inclined bed stokers are good for about 30 minutes, however I set-up a k-8 and we had it off for 2hrs....and it restarted itself......5 minutes, hands off, full fire. I was impressed. The K=6 won't last that long. Hell yes, leave it burning....try it year-round if it works out for you. I know several folks with the oil option, NONE have even piped it to the unit. That is how bulletproof they are.
