Warmup's cable is double-insulated with advanced fluoropolymers. That's because it carries a very high Ohms resistance in order to provide heat outputs 25%-40% than any other cable on the market.

Warmup systems heat the whole room. Our cable systems are provided with the necessary clips or tape in order to install it directly over concrete floors, 3/4 ply or cement backer boards. For the best results, consider our 1/4" cement-coated insulation boards.

Warmup cable can be spaced 2", 3" or 4" apart. The more density, the more heat. We traditionally consider that 2" is primary heating, 3" is standard and 4" is supplemental heating. Depending on your subfloor and with the use of Warmup Insulation Boards, you can optimize the system by using less wire thanks to reduced heatloss.

Cable systems are the professional's choice. They offer a high degree of flexibility and are perfect for custom layouts.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Plumbing fixtures can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new fixtures should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
