Anybody know if anti freeze will flow through an HVAC coil?

Getting ready to start my wood fired water furnace project for the barn build.
Using a modified 24" round air compressor tank for the stove, which will have a copper coil wrapped around it.
Most of the DIY videos show using a vehicle radiator, but I have an HVAC coil on hand, as well as a HVAC blower, and
I can fab up a plenum w/filter.
Just not sure if the anti-freeze will flow well through an AC coil.
Anybody know?
 
It should flow but at minimum it's a 3/8 line. Could be up to an inch. Just be sure to remove and metering devices.

Figured my best bet is to make a small tank near the exit end of the coil. and pump from that tank. AF would flow through the coil and into the tank, pump would pick up from the tank.
Maybe eliminating air in the line VS a closed system and allow the pump to regulate the flow with a constant supply of AF.
 
Depends on the air condition coil. Probably not on an A shaped coil. A slanted slab coil (square coil) and one that does not have small capillary tubes to sections of the coil. And as leemajors stated the metering device in any coil must be removed.

I like where your going with this and multiple coils spaced out would be nice with fans attached.

I know that you’re probably going for minimum cost, and I don’t blame you, but an old radiator would be very cool. Hipsters have discovered them, so hard or impossible to find free, but worth looking around. Worst case is somewhere like https://www.recyclingthepast.com/c60-Radiators.aspx where they seem to cost about $15 per chamber.
