You never answered the question as to exactly what type of setup you are looking for.

Yes, an inside boiler combination forced air is desired. The forced air is necessary for 1/2 the shop and radiant floor heat is set up in the back 1/2 of the shop.

I want to compliment the electric radiant heat with wood heat boiler. So here I am asking for advice on setting up the current wood furnace with a boiler for this purpose.

yes, wood boiler and they make water coil air handlers or just water coils that can be mounted in the ductwork.

There are many indoor wood boilers, NTI makes one, Viesmann (i think).
Hot water coils can be purchased online quite cheaply.

Your going to need to know a lot of info before you start to shop.

I think that what the poster is asking for is...

He has an existing wood fired 'stove' or possibly a furnace with ductwork for distributing the hot air around the shop.

It sounds to me as if he wishes to retain that wood fired appliance and fit some sort of 'attachment' to it in order to heat water and supplement an existing electric boiler which heats the water in his existing radiant floor system.

Do I have that right DJ ?

If so, I believe the answers that you've gotten so far are not exactly what you are looking for.

That is correct. Looking for either a new indoor wood boiler with forced air capability or an insert In my current wood furnace plenum To compliment electric boiler. I am aware of water coils to preheat water but is that feasible for this application?

After re-reading the replies, perhaps _I_ am the one that misunderstood them?

I guess you could install a water coil in the plenum to heat water... and then pump into the radiant, but here's the thing:

You want to take heat OUT of the AIR stream in the plenum and transfer it to the WATER that you will pump through the floor.

This COULD possibly work, but I would think that the air would have to be MUCH hotter than the water in order to get any real transfer from the air to the water.

What is FAR more likely to happen is that the air will pull even more heat from the water... in other words, it will probably work BACKWARDS to what you are wanting to do.

The water coming OUT of the coil will probably be cooler than the water going in!

Thanks a bunch NJT. What you are saying makes sense. Considering the cost outlay and payback period for the investment on this IF successful and the possibility that the benefit may be negligible or $0, I think I will set the idea aside at least for this year. Pursuing a standalone additional heat source for the area would be the more simple approach rather than mucking about with what is in place.
