I laid out the pec tubing by hand, then I realized I was running out....sooo I spaced the tubes 2 feet about apart, instead of one. I figured that the heat would still warm the concrete. To my surprise, I can rub my hand over the floor and feel the cool areas. It still works great, and this shows just how fast the heat escapes the concrete and enters the room air. My advise. Keep the 12inch spacing. Mars red, no way in hell I'm drilling my floors any where! I did put 2 small anchors at the bottom of staircase, without thinking. I woke up in the middle of the night and realized how lucky I was! I love the silent clean floor heat!
