I installed my pellet stove myself, roughly 2.5 months ago. It was given to me by my brother in law who upgraded to a sweet Harman coal feeder. After the installation I had the local chimney sweep in to give the stove a good cleaning and check the venting I did. They said it was fine. Talking to a co-worker today, he mentioned he got what he described as a "hefty bump" in his premium due to having a pellet stove. So first of all, I never told my insurance company I put in a pellet stove. Doing so makes sense to me now, but my hindsight is almost always 20/20. My big question is, is having a pellet stove just cause for your insurance company to hike your premiums?
