Our new house has a crawl space. We have purchaced heat tape from the "Warmup" co. and plan to do the job ourselves. I have read all the directions that came with the product. I know I have to put the tape and backerboard down with thinset and would like to know if anyone else has tackled this heat tape job and have any suggestions that might make the installation a little easier, we cannot afford to have it done because we are in a remote area and the nearest installers are hundreds of miles away and they require you to use their products. We are (old) seniors.Thanks
