Installing a hydronic radiant floor system in a slab-on-grade floor

Here is our DIY video of  how to lay down tubing for our radiant floor in the Edelweiss House. We have a 10 zone system, allowing floor temperatures in each room to be controlled independently. HePex tubing was provided by Uponor, who also use building plans to give customers a zone plan to follow making the install quick and easy, also ensuring the right length of run for each zone to ensure balanced heat throughout the house.

How come you guys didn't raise the rebar off of the vapour barrier ??
How much did it cost for all that insulation ?

Hi Eric

We raise the mesh with a rake during the pour. You'd have to check with Roxul to get a price on insulation, but I suspect your question is actually about whether or not it's worth it, and the answer in our opinion is yes. Based on energy modelling, the R32 we have under the slab will be a money saver. There is a misconception that heat rises (it is actually hot air that rises), so we don't insulate basements anywhere near what we should be, and we pay dearly in heat loss because of it. This page explains that in a bit more detail. Regards. http://www.ecohome.net/guid...

Hi Tiffany,

To get an accurate number you'd need to have a professional quote, but to ballpark it, figure on around $6 dollars a square foot, though if you are building your own house and do some of the work yourself you can save a bit of money.
