Does anyone have any experience with Greenwood wood furnaces? These woodburning units are supposed to have very low creosote and smoke emissions due to a very high combustion temperature. They have a massive ceramic heat sink that stays very hot so when heat is called for and air is blown in, the wood ignites from the high heat of the ceramic.
I'm looking to use it in my garage and pipe the hot water underground to my house 40 feet away using insulated PLEX tubing as per outdoor wood furnace installations.
