    the stove is a regular wood stove.  Am I correct?

    I've just bought a pellet stove that I will install in my own fireplace (replacing a wood stove).  

    I have 2 questions:

    I am concerned about the the fresh air intake.  Does anyone know if I need to have that pipe to make the stove truly efficient?  

    What's the best way of storing the pellets.  Most recommend buying them in quantities of a pallet rather than individual bags.  Can they be stored in a well protected area and still retain their 14% or so moisture content?

      The stove WILL draw air from somewhere,  either from your warm room,  or through a duct from outside.

        precious calories and transfer them to the new incoming cold air.  sheet metal concoction, designs found in green house idea websites...have link, can't travel right now...

        they are similar in concept to the air box around the heated vent pipe..the cold room air goes in, gets heated and comes back out, maybe with a fan.

        Obviously needs to be done right as the combustion air leak will kill you.

        But there are products for this.

    •  I had a pellet stove in my last house (15+ / 0-)

      Loved it, and hauling around 40lb bags of pellets was good exercise (that's what I tell myself - actually I kind of hated that part of it).

      I bought them by the pallet and stored them stacked in my sun room.  You'll go through a pallet surprisingly fast so there's really no worry about moisture unless you're keeping them in an outdoor shed or damp basement.

      I think that most newer pellet stoves don't require a fresh air intake but I installed one anyway when I put the stove in.

      I really loved the pellet stove - it gave out a ton of heat and burned much cleaner than a wood-burning stove.

    •  To operate an efficient wood stove (10+ / 0-)

      requires air intake with a cross section in square inches, not square feet like a fireplace. My first woodstove, a Jotul 602B, had a damper on the front and when fully open, the area for intake air was about 4 square inches. It would heat the cabin it was in from -25F to 90F in about half an hour (although the lower part of the stove pipe was glowing by then) and didn't use much wood.

      Unlike a fire place, you won't draw much outside air at all - probably less than existing infiltration unless your house is really air tight. If your house is that tight, you might have trouble even getting a good draft going for a wood burner without an intake, although a pellet stove would seem to need even less combustion air.

      However - check your local building codes (if you want to stay legal). WA State requires an outside air intake for wood stoves, at least for new construction. Most stoves have a simple adapter for accomplishing that, and you just need some flexible metal duct, couplings and a wall vent.

      Our house in WI, which was passive solar/super-insulated but not super-tight, could be heated on much less than a cord of hardwood a year without an external air intake.

      Modern revolutions have succeeded because of solidarity, not force.

      •  not enough intake air can screw with your gas (2+ / 0-)

        appliances so much they backdraft and suck combustion products in past the gas ring and into the house. Dryers, gas heaters, gas  hot water heaters.

        It cracks me up to read about all the crazy expensive detail people go thru to super insulate and super seal their house and then say,
        "oh, we bought a woodstove for those few times we need it...and I have to remember to crack a window" (yeah, before the headaches start!)

        anyway, most houses aren't that airtight, but if it's even a possibility, look into the need for it, it is not to be dismissed or forgotten.

        Of course you know all that, but around here there are always stories in the winter of people bringing BBQs inside, or even transients getting in an unoccupied house and building a fire on the floor, inside, not on concrete either.
