Hello, Were new to the boiler room. In fact were new to the internet. Ha Ha. The kids 9 and 11 years old know more then we will probably ever know. We are looking for information on choosing the best system for our situation and needs. Garn or EKO that is the question. Were heating a 5400 sq. ft. house two story walk out, well insulated. two 90 efficiency furnaces one on each end. Lots of Anderson windows and doorwalls, little R factor. On demand demestic Hot water system. Also want to heat a 32x48 two story pole barn. Pole barn does have a 9x48 over hang for possible location of boiler and wood storage. No heat source in barn as of yet. Boiler would set inclosed, 225 ft. from the house. We have a plentiful supply of wood. My wonderful wife of 17 years and I built the house and are not afraid of the work of cutting trees or installing the heating system. We are in need of any information to help us make a informed decision as well a properly designed install. If not for this web site , we would probably own a OWB, "Thanks"
