1,600 foot² Heated Driveway and Basement Floor Heating in Toronto

We are installing a 1,600 foot² heated driveway in Toronto and hooking up the already present tubing for the basement floor heating for this house under construction. The snow melt manifold will be mounted on the wall inside the cold room below the front steps. As usual we are using SharkBite’s 3/4″ O² Barrier Tubing for maximum volume and a quick snow melt cycle. The system will be filled with a 50-50 mixture of Propylene Glycol solution to prevent it from freezing in the tubes. This solution will stay liquid down to -35 Cº.

We begin with laying down the HotRock Panel Insulation that will hold the tubing in place and ensure that the heat reflected towards the surface. The gravel must be level so that the panels don’t wobble and bend when waled upon or they will either not hold the tubing or even break.

Using the HotRock Panels instead of the old style insulation and wire mash tie down system speeds up the process tremendously. These panels have the added benefit of incorporating a water vapor barrier on their surface. The insulation under this heated driveway in Toronto will retain its R-10 value  and will not absorb water even if ground waters wet their underside. Once an insulation absorbs water it becomes worthless.

Once the insulation is laid down precisely so that the groves match up it is time to start drilling under the steps and lay down the tubing.

Chili gets to play with the big drill today having to core 17 holes through 10″ concrete all the while avoiding ABS pipes on the inside wall of the cold room. The August sun is punishing, hard to imagine the days when this heated driveway will melt the snow on the daily basis.

Once all the pipes are laid and all the holes drilled the only thing left to do is to install the snow melt sensor’s conduit on this heated driveway.

All the holes have to line up with the groves. On a hot day like this the 3/4″ Sharkbite Tubing is very flexible. Try doing it in -10Cº and you have a fight on your hands.

If it looks good chances are it will work good. The outside work is done. Once the concrete is poured over, the interlock can be laid down for this heated driveway in Toronto.

The final step in the rough-in phase of a snow melt system is to pressurize the tubing to check for any defects and to be able to immediately realize during the concrete pour of any of the tubing is damaged. Air escaping at 130 Psi through wet concrete will not go unnoticed.
