Ok, in light of new information from this forum and a ton of reading I have been doing, I woul dlike to know how the money looks to comare the following designs for my home overall.  I would like to see what some of the items COST and the way they need to be configured to make the home work.  My desire is to heat with wood, but i understand now that the large exterior wood boiler is not the answer.  I wou ld like to employ a high efficency boiler inside the house if I can, along with a wood stove inside if I can.  Primarily the boiler would do the hot water for the radiant system in the floor as wellas our domestic hot water.  the wood stove would be for suplemetal heat in the home, so I will need another type mechanical system for heating and cooling in conjuntion with the stove.  Make Sense???
