Radiant floor heating consists of directly heating a mass rather than the ambient air. The feeling of comfort is far superior to conventional methods such as baseboards, wall heaters or the forced air system. With warm feet, the occupant is more comfortable while enjoying substantial energy savings.
Depending on the chosen product, FLEXTHERM systems are installed on most subfloors including: plywood, smooth concrete, concrete panels, ceramic, acoustic membrane, uncoupling membrane, crack bridging membrane, wire mesh under a scratch coat, mortar bed or even buried in a concrete slab. Just follow the recommendations in the installation guide provided by FLEXTHERM to get the best performance from your installation.
Depending on the product chosen, FLEXTHERM systems are compatible with a wide variety of floor coverings including: ceramic, natural stone, engineered wood, vinyl, floating floors, linoleum, parquet flooring and carpet.
For coverings other than ceramic or natural stone, it is important to always check with the manufacturer about the compatibility of their product with a floor heating system. Just follow the recommendations provided by FLEXTHERM to get the best performance from your installation. FLEXTHERM does not recommend the installation of heating cables under hardwood or cork.
In the case of a smooth concrete installation and to maximize the benefits of radiant floor heating, the concrete slab must be insulated to prevent heat loss. There are a variety of products available on the market to create a thermal barrier. The suppliers of insulation products will be happy to give you advice.
The cost varies from one installation to another. It depends on several factors including: local electricity rate (KwH), heat loss and insulation of the room, the level of comfort desired by the occupant and the duration of the heating. A radiant floor heating system can provide energy savings of up to 28% compared to conventional approaches.
Radiant floor heating can act as the primary source of space heating. Several factors are involved including: the level of insulation of the subfloor, the size of the room, the exposure of the external walls, the windows, the desired level of comfort as well as the power emitted by the system.
FLEXTHERM products can be installed on 120 VAC or 240 VAC circuits, also commonly known as 110 or 220. On special order, 208 VAC systems can be delivered for special projects. In all cases, it is mandatory to have a dedicated circuit for heating.
FLEXTHERM floor heating systems come with detailed installation instructions. A skilled handyman can install the heating cable by following the installation guide. You must ensure that the installation is done in accordance with the appropriate Electrical Code in your area. The thermostat must be connected by a qualified person where required by law.

Never! FLEXTHERM heating cables are manufactured to very high quality standards which are applied at the factory to maintain its integrity, its security and ensure a long service life. The cable is calibrated at the factory to meet the heating needs of a specific floor area surface. Cutting it will render it unusable and the warranty will be void. Splicing (joining two cables) should not be done under any circumstances.
Three options are possible:
Never! This will void the warranty. Always use the FLEXTHERM Universal Snap-In Gauges™, the FLEXSnap+ system or an uncoupling membrane.
FLEXTHERM has repair kits available for order to repair the severed or damaged cable. If necessary, FLEXTHERM offers support for the repair; please contact our Customer Service team.
Yes, the systems are approved for installation in a sunroom or solarium. Depending on the insulation of your solarium, the loss of heat due to windows and location, an additional heating system may be advisable to ensure better comfort during peak periods in winter.
Yes, the systems are manufactured using very stringent quality procedures and they meet the CSA and UL standards for wet installation. Rigorous manufacturing methods give the FLEXTHERM cable a distinctive advantage unmatched by competition.
Yes, the systems are manufactured using very stringent quality procedures and they meet the CSA and UL standards for wet environment installation. Rigorous manufacturing methods give the FLEXTHERM cable a distinctive advantage unequaled by the competition. A separate cable from the one covering the floor of the bathroom is recommended in the shower.
The time required before installing the tiles after the first coat will be dictated by the products used. In general, between 3 and 24 hours of drying are necessary. Check with the supplier or manufacturer of the products used.
The curing time (cure) varies from one product to another. Mortars and self-leveling underlayment’s take some time to fully cure. They can take up to 28 days to cure completely. Consult the supplier or manufacturer of the product for their recommendations. It is not possible to accelerate the curing by heating. The consequences could be detrimental to the final quality of the cured product.
The cost per square foot is difficult to calculate because many factors influence the price. First of all, you will need a thermostat regardless of the area covered, whether it is a room of 20 sq. Ft. or 200 sq. Ft. You will have to absorb the cost of the thermostat.
Thereafter, will you be installing with the use of a membrane? What will be the spacing of the cable? The type of floor covering? What will the subfloor be? Which cable model/size? The larger the area, the lower the price per square foot.
For the purpose of giving you a realistic price contact our customer service or make an online quote.
No, the system is protected by a built-in GFCI (Ground-Fault Circuit Interrupter) at the thermostat which will shut off the power in the event of a fault. In addition, as the cable or mat is buried in the concrete / mortar there is no oxygen, so no risk.

The FLEXTHERM thermostat is used to precisely regulate the temperature of the floor of the room where it is installed using a probe (sensor) in the floor. Also, thanks to the built-in Ground-Fault Circuit Interrupter (GFCI), it will protect the occupants of the room and the heating cable itself in the event of a system malfunction.
Consult the programming guide provided with the thermostat, or contact our Customer Service team for assistance.
A thermostat can accommodate multiple sets of heating cables that do not exceed 15 amps of load current in total. Beyond this level, expansion units in combination with a thermostat will take over. Each room must have its own thermostat.

The red light is connected to the ground protection.
If you pressed on the thermostat TEST button, the red light will come on. The test is therefore conclusive. Press the RESET button to restart the thermostat.
If the red light is on and you have not pressed on the TEST button, you can press the RESET button to restart the thermostat. If ever the red light comes back, please contact our customer service.
The TEST button is used to check the GFCI.
In the case of a ceramic tile covering, it is possible to install one probe sensor between two ceramic tiles (in the grout line).
Otherwise, it is also possible to put the thermostat in the ‘ambiant’ mode. However, please note that this setting isn’t optimal for certain conditions.
Contact our Customer Service team for help.
FLEXTHERM includes a floor sensor with the thermostat and also one with each box of cables or mats. You can install both probes in the floor as per installation guidelines. Only one should be connected to the thermostat. In the case where a sensor was not well positioned in the floor, it is easy to disconnect the sensor and reconnect the other to the thermostat.
