Well, I am going the expensive route and with my dad's help we are building the tort table with radiant heat and tile! (on the bottom and sides) The sides are going to be secured enough so the tile won't have a issue with cracking, I think we are going to use color matched silicone (to the tile) inbetween the tiles. I think they are slate tiles? Anyhow, this product, with a thermostat, is going to be installed under the tile: http://www.warmzone.com/heated-floor-mats-details.php It was about $250 and the people that sold it to us gave us the tile for free, along with the "thinset" and silicone. My question is, with a little cover over the top of the 6 foot by 3 foot enclosure, do you guys think this way of heating will heat the entire enclosure so that I will not need another heat source? Of course it will be waterproof and some sort of way to introduce humidity will be provided. This thing has a thermostat, you can adjust the temps from 60 something to 99 I think, I am not sure of the actual temps. This is going to be for a redfoot. Thanks!
