I am planning out my Tarm Excel 2200 install and am working through my exact storage needs/desires.
Today's goal: design the copper coil heat exchangers.
I have a good friend in the plumbing industry who can setup me up with copper coils at his cost, so I figured I would take a stab at building my own exhangers.
The Tarm is 140k btu rated on wood.
What length/diameter copper coils will I need for space heating?
How about DHW?
I am planning on a ~800 gallon storage tank.
