I am starting a new house in NC and it will have a pretty steep drive. In the winter we get ice storms so I would like to install snow melting capability. I’m on a pretty tight budget so initially I only want to do what’s absolutely necessary.
My idea is to install tubing in the concrete when the drive is poured and then finish it up at a later date. I read through a number of radiant heat threads and still have some questions:
1: Can I use polyethylene tubing in air-entrained concrete?
2: My drive is 10ft wide by approx. 100ft long. I thought I would snake the tubing back and forth horizontally from the top (house) to the bottom (street) spacing each run about 1 ft apart, then run the return line straight back up. Does this sound reasonable?
3: Do I need to do anything special at the stress joints?
4: Should I put a foil reflector down first? I don’t want to put any foam insulation under the drive, but thought foil might help some.
