Installing Radiant Heat Between Joists. Retrofit radiant heat into your home or for new construction

[@unimogdave]

I am doing the same installation on I-Joists. What if the home owner decides they want hardwood. How do you nail it with pipe so close under the floor? I will be mounting my Piping to the joists just under the top "I" so they will be at least 2 inches below the subfloor.

I wonder if you have radiant heat in a concrete floor will it make the concrete brittle or crack over time? Due to the heat drying the concrete faster than normal?

Thanks for writing. Heated water should not be run through the tubing before the concrete is completely cured. Once the concrete is cured fully, the radiant heat will have no impact whatsoever on the slab.

Also D-head/angle 1/2 drill $250 usd to start.

Not at all necessary. You can buy a right angle attachment for your drill for around $25.
