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.

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

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.

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

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.
