I have 4 years experience with wood dr. You must burn the driest of wood. Never green wood. Wood cut and split sitting on pallets and covered with old steel roofing is still 20% moisture. Never cover sides of woodpile as it keeps in the moisture. On the stove I just retrofitted the 16 inch stovepipeo it is insulated and covered with a stainless steel outer pipe. Also the factory stove pipe covers are worthless, they allow rain water to enter the chimney. I replaced mine with a large piepan type cover mfg by Burkholder Sheetmetal in Epharta, Pa. All stove pipe must be insulated stainless. Cold uninsulated steel pipe condenses the moisture from the water in the burning wood and runs down the chimney and will rust the burn chamber. Back 100 years ago people saved white wood ashes, put them in an old wooden barrel with holes in bottom end, poured rain water in open end of barrel and the water coming out the bottom was lye water to make soap. They caution however that lye water will rust through steel pans. So if you have any water and ashes in the burn chamber it causes this lye water mixture which is caustic to the steel. For hot water heat my temp differential is set at 170-190 and I set house thermostat at 72 degrees 24-7. I see no moisture at all in the chamber or around the door operating with these conditions. Radiators in the house are always warm, also I have a 200 gallon hot water tank in cellar which is always 132 degrees and we heat the hot tub daily. A hot water boiler is way different than a wood stove, it must burn as hot as possible with very dry wood or it will self destruct with corrosion.
