Sorry if this seems a little off topic, but you guys know metals
better than anyone, so here I am.
My basement slab has pex tubes in it. I would like to put some coils
in the chimney of my wood stove on order to capture a little more
heat. There will be an intermediate LP fired 80 gallon HW heater in
order to moderate temperature of water going into pex tubing. I want
to keep water near 120F and do not want to chance overheating pex
tubes in slab. They are a bitch to change out. I will most likely be
running automotive type glycol thru systerm.
I am thinking to use copper tubing for coils. I think the coils
should probably be plated with nickle (or even chrome) to resist
corrosion. Other materials, stanless, monel, inconel are also a
possibility. I'm looking for advice on coil material that would be
reasonably priced.
I realize there is the chance of creosote buildup in the stack and the
danger of steam explosions and so forth. I intend to monitor the
stack by inspection and run a pressure relief valve and low water
alarm. that will shut off air to stove.
thanks,
Bob
