I have a 5 ton Climate-master Unit. It works well no compliants. We are looking at ways to supplement it with Wood. We live in a forest, I own a log-splitter. I have seen the wood boilers that are outside units. I was wondering if it is possible to run the geothermal loop through one of those, so by burning wood we would be heating the loop, thus giving us additional BTU's on those cold January and February evenings. The other option would be getting an internal wood furance and then booking that into the duct work after the geothermal unit.

Thoughts, ideas?

I can't discuss the geothermal part of your question, but years ago I lived in a 1200 sq. ft. home in Pocatello, Idaho that had an oil stove in the basement along with, siting next to it, a wood furnace. The wood furnace was double walled with a thermostatically controlled blower on the bottom blowing through the space between the two walls which terminated in a 4" round duct at the top. This duct then went into the outlet duct from the oil furnace. I could fit 3 or 4 pieces of Douglas Fir into the furnace whidh would produce enough heat to heat the house for 4 - 6 hours. I'd feed it in the morning, noon, supper, and before I retired and it did just fine. The only time the oil was on was if I was going to be out of town for a day. Probably burned a couple of cords/winter. As usual, YMMV!
