The HeatTech 30 sq ft mat is a larger 120V option with adhesive backing and an included AUBE TH115-AF-120S 7-day programmable thermostat. The mat uses 12 W/sq ft nominal output and includes a 10 ft cold lead for wiring.
- Design: 20″ wide x 18.3 ft long mat that lays flat without staples and can be cut to make turns on the mesh backing.
- Power & Performance: 360 Watts total load at 120V, zero EMF design is noted for this model.
- Thermostat: Aube programmable floor sensing thermostat included for accurate floor temp control and energy scheduling.
This kit is suited to medium-sized rooms where a slightly higher coverage and pre-matched thermostat are desirable for consistent floor temperature control.
All-In-One Electric Radiant Floor Heating Kit 51 Sq Ft 120V – GTDsupply
This GTDsupply kit targets larger coverage areas with 51 sq ft capacity and includes heating cable, a DHERT102/BW touchscreen programmable thermostat and heat uncoupling membrane compatibility for DITRA-HEAT installations.
- System Components: Heat cable, touchscreen thermostat, heat uncoupling membrane compatibility and two floor sensors for redundancy and flexible placement.
- Thermostat Flexibility: The DHERT102/BW supports 120V systems and offers multiple programmable cycles and touchscreen controls for tailored schedules.
- Installation Context: Designed for use with uncoupling membranes (e.g., Schluter DITRA-HEAT) to address waterproofing, decoupling, and heat distribution under tile.
Suitable for larger bathrooms or living spaces where membrane-based decoupling and robust thermostat controls are required during installation.
Dr Infrared Heater DR-238 Carbon Infrared Outdoor Heater – 120V
The Dr Infrared DR-238 is a plug-and-play 120V carbon infrared heater designed for both indoor and outdoor use with an IP55 rating. It provides instant radiant heat with three power settings and remote control.
- Power Settings: 900W, 1200W, and 1500W options (120V supply) to balance heat output and electrical limitations.
- Durability & Use: IP55-rated for resistant operation in open-air conditions, suitable for patios, decks, garages, and restaurant outdoor spaces.
- User Convenience: Remote control operation and plug-and-go design reduce installation complexity compared to built-in radiant systems.
This unit fits situations where temporary or portable radiant warmth is needed without construction—outdoor seating areas, garages or workshops where controlled infrared heat is preferred.
Buying Guide: Choosing The Right 120V Radiant Heater
Decide between built-in radiant floor systems and plug-in infrared heaters first. Each approach serves different needs: floor systems provide long-term, even warmth under finished flooring, while infrared units deliver immediate directional heat for open-air or temporary spaces.
Application And Coverage
Floor Heating Mats/Cables: Select kit area size (sq ft) that matches the planned room footprint. Allow for fixture, cabinet, and plumbing offsets. Typical mat outputs are around 12 W/sq ft for comfortable floor warming.
Portable Infrared Heaters: Match wattage settings to the intended open-air or enclosed area. Higher wattage (1500W at 120V) produces more radiant output but consider available circuit capacity.
Electrical And Circuit Considerations
120V systems draw current from standard household circuits. Confirm the circuit ampacity and existing loads. Many kits list amps and watts—use these to ensure compatibility with a 15 A or 20 A circuit and avoid overloading.
Thermostat And Controls
Look for floor-sensing thermostats for radiant floor systems to control floor temperature rather than just air temperature. Programmable and touchscreen thermostats add scheduling and energy savings. For portable infrared units, remote control and multiple power settings improve usability.
Safety Features
GFCI Protection is critical for wet-area installations—many floor kits include built-in Class A GFCI in their thermostat or cable. Installation monitors that alarm on wire damage are valuable to detect issues before covering the mat or cable.
Installation Requirements
Floor heating cables typically require embedding in thinset, self-leveling underlayment, or mortar; some systems are designed to work with uncoupling membranes like DITRA-HEAT. Follow manufacturer constraints: do not cut heater wires, embed to specified depth, and install sensors as directed.
Flooring Compatibility
Confirm compatibility with your finished flooring—tile and stone commonly pair well with radiant cables and membranes. Some systems support laminate and engineered wood when installed according to manufacturer guidance and thermal limits.
Warranty, Certifications And Support
Choose products with clear manufacturer warranties and UL/cUL or other regional listings. Extended warranties and established manufacturer support can be decisive for built-in systems that are covered and concealed once installed.
Performance And Efficiency
Compare watt/sq ft ratings and thermostat scheduling to estimate runtime and energy usage. Floor systems typically maintain comfortable radiant warmth at lower runtime compared to forced-air heating for localized comfort.
Installation Type: DIY Vs Professional
Some kits are marketed for DIY with clear instructions and included thermostats and monitors. However, electrical hookup to branch circuits often requires a qualified electrician. Complex installations involving membranes or uncoupling layers may benefit from a tile contractor or flooring professional.
Comparison Perspectives
- Small Area Budget Install: Choose lower-area mats (10–25 sq ft) with included thermostat and installation monitor for bathrooms or targeted zones.
- Large Area Or Membrane-Based Install: Look for cable kits and kits designed for use with uncoupling membranes for better crack prevention and waterproofing.
- Temporary / Outdoor Heat: Use a 120V infrared model with IP rating and multiple power settings for patios, decks and garages that need directional heat without construction.
When comparing candidates, weigh coverage size, thermostat features, safety (GFCI and installation monitor), listed output (W/sq ft), and whether the kit includes membranes or uncoupling products for your subfloor type.
