The breaker and wire sizes are selected based on the total amperage of the WarmlyYours heating system connected to a single thermostat. This information is on the WarmlyYours heating system'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.

In theory, it is possible, if no other options are available. We do not recommend it, but If the thermostat is controlling the floor temperature with a floor sensor, then it can go on an exterior wall. It is important that the floor sensor gets located in an area of the floor not hit by sunshine.

If the thermostat will be controlling the air temperature with the built-in ambient sensor, then it should go on an interior wall.

A GFCI/GFEP (Ground Fault Circuit Interrupter / Ground Fault Equipment Protection) works differently than a circuit breaker by specifically detecting a small imbalance in electrical current between the hot and neutral wires, which indicates a potential ground fault (like a person touching a live wire), and instantly shutting off the power to prevent shock, while a circuit breaker only trips when there's a significant overload in current flow on the circuit, like a short circuit or too many appliances plugged in.

Relays can fail due to excessive current or voltage. When a relay is exposed to too much current, the contacts can burn out. High voltage can also damage the coil. Other reasons include mechanical wear and tear, dust or dirt buildup, and moisture. These factors can cause the relay to malfunction or stop working entirely. Regular maintenance and using the relay within its specified limits can help prevent failures.

No, a circuit breaker will NOT protect against a power surge; a circuit breakers primary function is to protect against excessive current flow (overload), while a surge protector is specifically designed to handle voltage spikes, which are what power surges are considered to be.

The flashing digits indicate that the actual (measured) floor temperature exceeds the thermostat temperature limit.

The temperature limit is set for either tile (104°F/40°C) or laminate (82°F/28°C) when the thermostat is first set up or re-configured.

For example: When the floor type (protection) is set to laminate, the limit defaults to 82°F/28°C. If the floor temperature goes above this - whether due to radiant floor heating or external heating sources, then the digits will flash and the heating is switched off.

Turning the temperature up or down will not affect the flashing digits. And leaving the thermostat alone with flashing digits does not harm the system.

Tip: To turn off the heated floor (ex. for months when it is not needed), on the outer edge of the thermostat, depress the lower right side button for 3-5 seconds. This will also turn it back on.

Yes, many homeowners successfully install bathroom floor heating systems themselves. WarmlyYours provides detailed installation manuals, 24/7 technical support, and custom installation plans to guide you through the process. However, a licensed electrician is required to perform the final electrical connections and thermostat wiring to ensure safety and warranty compliance.

Yes, radiant floor heating can be a primary heat source if its heat output exceeds the room's heat loss. For best results, we recommend using a 15-watt system, covering at least 80% of the floor, and ensuring the space is well-insulated. Use our Heat Loss Calculator to verify your specific needs.

Was this helpful? Yes No

Yes, radiant floor heating is an excellent primary heat source for tiny houses in mild to moderate climates. Because tiny houses have small footprints, the 15-watt output of TempZone™ can easily maintain comfort while saving valuable wall space. Ensure the structure is well-insulated and use our Heat Loss Calculator to confirm.

Was this helpful? Yes No

No, the RC-40AMP is controlled by a line voltage (120V/240V) thermostat.

Yes, bedroom floor heating can be a DIY project. Systems like TempZone Easy Mats or Environ Flex Rolls are designed for straightforward installation under various flooring types. While you can lay the heating elements and flooring yourself, you must hire a certified electrician to connect the system to power and install the thermostat.

Was this helpful? Yes No

Yes, we strongly recommend installing insulation like ThermalSheet™ over concrete slabs. Concrete acts as a "heat sink," absorbing warmth that should go to your floor. Insulation directs the heat upward, significantly improving efficiency, reducing warm-up times, and allowing the system to function effectively as a primary heat source.

Was this helpful? Yes No

Underlayment is recommended for floating floors (laminate, LVP, wood) and installations over cold subfloors like concrete. It provides thermal insulation to prevent heat loss and improves system efficiency. For tile and stone, the system is typically embedded in thinset, so a separate underlayment is often unnecessary.

Was this helpful? Yes No

To prepare a basement for radiant heating, ensure the concrete subfloor is level, clean, and free of debris. It is highly recommended to install a thermal break, like WarmlyYours CeraZorb, over the slab to prevent heat loss into the ground. Finally, verify that your electrical panel has sufficient capacity for the system's requirements.

Was this helpful? Yes No

WarmlyYours TempZone™ Flex Rolls and Easy Mats deliver 15 watts per square foot, the maximum allowed by the National Electrical Code. This provides 25% more heating power than the 12-watt industry standard. TempZone™ Cable can be spaced to deliver between 8 and 15 watts per square foot depending on your needs.

Was this helpful? Yes No

Yes, electric radiant floor heating is ideal for basements because it warms the cold concrete slab and provides consistent heat from the ground up. In well-insulated finished basements, it can serve as the primary heat source, turning a typically chilly space into a comfortable, year-round living area.

Was this helpful? Yes No

Radiant floor heating can heat a sunroom if the space has high-quality insulation and double-pane glass. Since sunrooms have high heat loss, a 15-watt system is essential. In extremely cold climates or poorly insulated sunrooms, it is best used as a supplemental source to keep the floor comfortable.

Was this helpful? Yes No

Yes, radiant heating is highly efficient in cold weather. Unlike forced-air systems that lose heat through ductwork and rising air, radiant heat warms objects directly via far-infrared energy. This method is up to 45% more energy-efficient, providing consistent comfort while significantly lowering monthly heating costs in frigid environments.

Was this helpful? Yes No

Both 120V and 240V systems provide the same level of heat and comfort. The choice depends on the size of your project; 120V is typically for smaller areas like bathrooms, while 240V is more efficient for larger rooms. Always consult your electrician to ensure your home’s electrical panel can support the system’s requirements.

Was this helpful? Yes No

An uncoupling membrane like Prodeso provides a flexible layer between your subfloor and tile, preventing cracks caused by natural floor movement. It also offers waterproofing and vapor management, making it ideal for bathrooms. Plus, the membrane’s studs make cable installation fast and consistent without the need for staples or glue.

Was this helpful? Yes No

The best home features for cold climates include a simple gable roof to shed snow, covered entrances for protection, airtight triple-pane windows to prevent heat loss, and radiant heating systems. These features work together to maintain interior warmth, reduce energy bills by up to 25%, and ensure structural safety during harsh winters.

Installing floor heating under carpet involves placing Environ heating mats over a pad and then covering them with the carpet. The process typically includes:

  • Installing a specific radiant-compatible carpet pad.
  • Laying out the Environ mats according to your plan.
  • Securing the mats with tape.
  • Having a professional installer lay the carpet over the mats.

GFCI can fail for various reasons, such as wear and tear, moisture, corrosion, power surges, faulty wiring, or improper installation. Some of these causes can be prevented by regular inspection and maintenance, while others may require professional assistance. It is important to note that GFCI devices (ex. thermostat, breakers, outlets) should be tested regularly as these do wear out over time.

Was this helpful? Yes No

Most systems provide only 12 watts per square foot, which often lacks the power for primary heating in cold climates. WarmlyYours TempZone™ delivers 15 watts—a 25% increase. This higher output allows the system to overcome heat loss more effectively, providing reliable primary warmth even when outdoor temperatures drop.

Was this helpful? Yes No

A floor sensor is essential because it monitors the actual temperature of your floor, preventing overheating and ensuring energy efficiency. It allows your thermostat to maintain your desired comfort level precisely. WarmlyYours even includes a backup sensor with our systems to provide long-term peace of mind and reliability.
