Re: wood vs pellet stove
One of the advantages of a pellet stove is that you can get thermostatic controlled ones that will automatically regulate the amount of heat better than a wood stove.
From the studies I've seen the cost of operation of a pellets stove is very close to the cost of gas heat, and what happens when your supplier is unable to re stock pellets, which has happened. All pellet stoves that I know of require an electric motor for an auger so it doesn't supply heat when the power is off.
As stated above wood burners are not permitted in some areas and it can even negate your insurance policy. Cost of wood is going to depend on whether or not you have your own supply and are capable of cutting a splitting the wood.
