It seems the consensus around here is they cost to much for what you get out of it. I am very concerned about electrical power consumption. It is hard to find the power use on either a gasifier or a heat pump. Anyone have any idea how they would compare? I have 240 acers so wood is not a problem. we are building with ifc so the building will stay pretty cool in the summer. propsed building is 3300, we have been told that we would need about a 4 or 5 ton system, but what the heck does that mean. I would just like to hear some exchange on geo vs. gasify.
