When installing electric floor heating over a concrete slab, an insulating underlayment like CeraZorb is highly recommended to ensure efficient operation, faster heating times and warmer floor temperatures.

The amount of amperage draw depends upon how large the area is that you are heating. For coverage of areas less than 30 square feet, the system will draw less than 3 or 4 amps. If you have a larger area over 120 square feet of heated space, then you may need a larger breaker plus additional controls. No matter what the size of the area you choose to heat, we recommend a dedicated circuit for your electric radiant floor heating system.

When WarmlyYours electric floor heating systems are being installed on a concrete slab, we strongly recommend adding a layer of insulation over the slab prior to installing the system. While our electric floor heating provides up to 25% more heating power per square foot than many of our competitors, the slab will always act as a "heat sink." Some of the heat that would otherwise be transferred to the flooring surface will remain in the slab, causing the floor’s surface temperature to be considerably lower. This is true with any electric radiant floor heating system.
When installed on top of a concrete slab without insulation, it is generally accepted that electric floor heating will take the chill away from the floor and provide a small amount of warmth. Adding insulation on top of the slab and beneath any electric radiant floor heating system will allow a greater percentage of the heat generated to transfer to the flooring surface. This results in greater efficiency and therefore faster warm up times, higher expected surface temperatures and lower energy usage. The floor will have the capacity to warm to a comfortable temperature, and in some cases can be employed as the primary heat source for that room.
The recommended types of insulation are natural cork, insulated tile backer boards and insulated underlayment, such as CeraZorb synthetic cork.

Breaker and wire sizes are selected based on the total amperage of the heating system connected to a single thermostat. This information is on the heating product's installation plan, electrical plan, or UL label. Based on guidelines from the National Electrical Code: loads up to 16 Amps may utilize 12 gauge wire with a 20-Amp breaker, and loads up to 12 Amps - 14 gauge wire with a 15-Amp breaker. Local code and/or other factors may change these guidelines.

One thermostat can control multiple heating mats/cables as long as all the elements are using less than 15 amps. For TempZone™ Flex Roll systems for example that would be maximum of 120 sq.ft. for 120V systems and 240 sq.ft. for 240V.
