I must first say that I'm not a roofer (nor do I play one on TV). I am in the radiant heating industry but isn't a metal roof over an asphalt shingled roof with an air gap betwe...
Replies 32How much mortar/tile did you add over the top of the existing slab in total?
Replies 36Now I understand why they made you cut them in 2-3/4" apart. If you only cut 3/8" deep. If you don't sink the cable in at least 1" -1-1/2" deep, they will not have enough depth ...
Replies 36DaVinci, Well, I don't mean to close the door after the horses are out but you could have saved considerable cost on the materials and labor. Though cutting "kerfs" , we call th...
Replies 36As mentioned here before, the key issues are temperature swings and moisture content. We have many clients who have installed an electric radiant system (called Zmesh) under oak...
Replies 10Good point! You are right. The system is always on and maintains 80 degrees. It takes almost 4 hrs to heat up from cold. The italian stone cutter (yup, shipped in from italy) ...
Replies 8"Works in practice"?? Do you mean, does it actrually heat the tub? Silly wabbit! I should add that the element was then mortared over to act as a heat sink and something to keep...

Replies 7First, let me say that we install both systems. So I'm not selling my product. The only reason i am particular to the low voltage is that it's easier to fix when someone else da...
Replies 9There re basically two types; line voltage cables and mats or low voltage cable. They both work effectively. The more popular known line voltage mats seem to last longer than t...
Replies 9Here's another way using low voltage: Scroll to the pix at the bottom of the page.

Replies 24Have you turned the floor system on yet? Sounds like you may end up with some cold striping if you separated the wires too much. Did you take pictures?
Replies 13Gettingby is saying that all electric systems are 100% efficient in that all of the electricity used becomes heat, none is wasted. However, if you install it on a concrete slab ...
Replies 8We install it all the time. It can be installed directly on the concrete or, for a more efficient system, install a barrier type insulator than a plywood substrate, then the zme...
Replies 8Depending on the open square footage and the heat load, you might be able to use low voltage as primary. Do the heat loss calc first and then come back.
Replies 9It's low voltage electric.
Replies 3It was difficlut to capture the 16 degree grade on this asphhalt driveway. We retro-fit a low voltage snow melting system in the summer of 2010. The 'after' picture is the morni...
