It still sounds like you are not getting your heat into your house. What size are the lines you put into the ground? You said you have 100 feet of insulated pex. So the boiler is 100 feet in one direction away from the house. Is that correct? Or is it 50 feet in one direction from the house?
Next, after size of pipe, what type of circulation pump are you using? Is it a single speed pump? Or is there different speeds it can be set at. I am wondering if you can get enough BTUs through your pipe and into your system fast enough.
Another thing. Can you draw us a basic diagram of your plumbing so the more experienced guys on here can have a look at it. I am not a plumbing expert for sure, but there are many good guys on here who could help you through your problem. Even with a poor design of a boiler, if that is part of the problem, I would think you should be able to do better than you currently are.
And pictures. Pictures would also help. Take a picture of the boiler, the connections of pipe to it, the connections of pipe coming through the house, the circulation pump that gets water from your boiler to your house, connections at plates, etc.
Is there a second circulation pump in the house that moves your heat through your radiators and baseboard registers? Have you been able to tell if the water is moving through your radiators, baseboard, etc.?
Is there another boiler in the equation? Is the water that is coming into the house from your outdoor wood boiler (OWB) plumbed to that second boiler? In other words. Are the boilers plumbed in series? Or are they plumbed in parallel? In parallel the water from your OWB would be able to go right past your indoor boiler and to your heat distributors.
Sorry about all those questions. But if you take the time to answer them you may spark someone here, probably other than me

, to help you figure out what your problem is. Keep this going and they will help you figure it out.
Oh. When you say the wood is dry. How do you know? Have you split on of the splits open and put a moisture meter to one of the freshly split sides? If not, buy or borrow a moisture meter. They can be had for about 25 or 30 bucks at Lowes. See what your moisture content is in the wood. And let us know. What type of wood are you burning? Lots of creosote sometimes means wet wood. But I would think you should still get higher temps of water in your system than you are.
