cool Lance , love the infloor heat !! I hope you'll continue keeping us "in the loop" here
About 102' of 1/2 PEX installed into the floor with 2 layers of foil face bubble wrap underneath. The tuck tape to keep it from springing out.
Covered in aluminum to spread out the heat and flattened out the floor. The water will be heated with a on demand propane heater. This will be all thermostatically controlled. I really enjoyed planning it out and installing it.
