We installed a pellet stove in November in our beach house ( on the Puget Sound, WA) basically it's the only source of heat, this is a fixer upper. It didn't really seem to put out the heat, so we installed an OAK ( per the dealer recommendation) and it really seemed to make a difference in the heat ou put. Well, right away I noticed the rust on the burn pot- seemed like no big deal, it's easily replaceable and made of thick stuff. Well last week end I noticed that the heat exchanger tubes are rusting as well as other parts like the feed tube where they pellets come out of the hopper. The hopper is okay. I took a picture and showed it to the dealer that sold us the stove. He contacted Envirofire right away, and they said they've never heard of this, but maybe we were using bad pellets, or lived on the coast... bingo- on the coast. they recommended that we plug the outside air intake. The delaer said it shouldn't make a difference in the stove heat output ( disagreeing with the advice he had already given us) So what do you guys think- anyone here have an OAK and live on the saltwater and have problems? This is a 1000 sq foot beach house that we usually just come out for the week-ends. What do you thik of the advice w've been given?I was thinking of using Damp rid in the box when we leave- would that help also? I'm very dissapointed to say the least, esp since we didn't get any great deal on the stove because we NEEDED to have some heat. But the dealer does seem to be approachable, if not very consistent. thanks for any help.! sorry about the huge picture.
