ThermoSlab^® Cable

ThermoSlab is a system of rugged heating cables tough enough to be installed directly in a new concrete foundation, or in the sand beneath a slab. ThermoSlab gives you the most permanent access to radiant heat as it survives any remodel, and even allows heat storage due to concrete slowly releasing heat over a longer period compared with typical floor coverings.Shop Now

Yes. All our floor heating solutions endure rigorous development and quality control testing to ensure that your floor heating system is reliable and safe. Due to the shielding and dual cable design used in ThermoSoft products, our radiant heat systems add virtually zero EMF. Shop Now

ThermoSlab is installed directly in your foundation slab concrete, so any floor covering that can be installed over a concrete slab can be installed over ThermoSlab.Shop Now

ThermoSlab is arranged before pouring your concrete slab and can be attached to mesh or rebar if you are using those materials to make arrangement of the cables easier. Make sure to read the full Installation Manual before beginning! ThermoSlab cables are wired to a floor heating thermostat in parallel. The number of cables and layout of the room will affect the exact process of how to wire the heating cables together. Please see the Installation Manual for explicit directions, or contact our in house experts for assistance. Shop Now

No, the ThermoSlab cable will be embedded in the concrete and will not add height in any way.Shop Now

ThermoSlab can be installed in concrete that is 2 inches or thicker.Shop Now

If you are pouring concrete at less than 2 inches, ThermoTile Mats will be a better fit. Not sure how to proceed? Give us a call and our experts will gladly help!Shop Now

Many projects involve using more than one cable, but this means that multiple cables are wired in parallel to the thermostat. The thing to remember is that you are not daisy-chaining or extending the heating cables, but rather the cables are working together to cover the appropriate square footage by connecting them in parallel to the floor heating thermostat.Shop Now

No. We do not warranty the cable when the heating element has been cut. Call us in advance and our floor heating experts will be able to match your project with the correct length of heating cable and advise on how to properly lay it out.Shop Now

Yes. The lead wires, also known as cold leads because they do not produce heat, can be cut, shortened, or spliced with additional cold lead cable to lengthen them.Shop Now

Floor covering is installed as normal over the heated and non heated areas of the slab.Shop Now

Yes! ThermoSlab is a rugged and durable cable that we recommend specifically for this type of application. We also highly recommend using one of our InstAlarm Monitors during installation. The InstAlarm Monitor is a device that connects to the lead wires and will produce a loud sound if there is damage to the heating cable.Shop Now

This figure can vary if the cable spacing deviates from the 5 inches on center spacing, but the standard output of ThermoSlab is about 14 watts per square foot.Shop Now

The cost to operate is a complicated question to answer, as electrical rates vary by area, your home's insulation, and even by time of day. Additionally, a cost-to-operate is further complicated because the money spent on your radiant heat can result in a net savings on total utilities cost due to reduced use of your traditional HVAC, which is added to by the fact that you will spend less on HVAC system maintenance by relying on electric radiant heat.Shop Now

Sometimes, we like to answer a question with a follow-up question. Usually, we are asked about “how hot” a system gets for a couple of reasons, so it is important to understand whyo you ask? Are you concerned about providing enough heat to adequately warm your space? If so, a properly installed ThermoSlab can provide about 10-15 degrees Fahrenheit of temperature difference above the ambient temperature of the room. In practice, this is more than enough, even in extremely cold climates. We are positive that you will be entirely satisfied with the heat produced by ThermoSlab. Are you concerned about applying too much heat to your chosen floor material? If so, fear not! ThermoSlab is designed to apply heat gently and evenly, due to the nature of the heating elements and the cable spacing pattern that it features. Additionally, ThermoSlab sits in concrete, which allows the heat to disperse warmth gradually and evenly. Depending on the floor covering you use, you may want to control your heat a little differently. Certain floor coverings are more temperature and temperature-change sensitive. Call us to have an our in-house experts go over some of these radiant heat “best practices.” Lastly, we highly recommend choosing a thermostat that includes a temperature limiter if this is one of your concerns!Shop Now

ThermoSlab has no moving parts and therefore it does not require regular maintenance once installed correctly and if left undisturbed (remember your radiant system is down there when planning a remodel!). The heating cables are warrantied for 10 years, but after multiple decades on the market, we have yet to see a system fail due to old age. The thermostats that we offer are warrantied for 3 years because we only use thermostats with GFCI protection which, per national electric code, is recommended to be replaced every 3 years. Replacing a thermostat is simple, easy, and inexpensive.Shop Now
