Thanks. I remember you giving me advice some time back on this subject but flex watt was what I was interested in using at the time. You also mentioned heat panels as well. I agree that they would be nice to use...but right now, I am on a pretty strict budget. Since this will be the 1st enclosure I have ever done, I want to see how things will work and maybe put more money into another on later one down the line.
I was planning on going with a heat pad under the tile and water proof all around with a thermostat attached to control the output.
