LuxHeat 100sqft Floor Heating Mat Kit

Best for medium to large spaces, this kit uses a 120V mat and UW4 WiFi-enabled thermostat with alarm and sensor. It enables centralized control through WiFi and is suitable for tiled or laminated floors. Choose this if you want smart control across a larger area.

LuxHeat 15sqft Floor Heating Cable Kit

Best for small, targeted spaces, this cable kit includes a WiFi-enabled UW5 thermostat, sensor, and alarm. It’s suitable where a quick, localized warm zone is needed. A caveat: coverage is limited, so larger areas may require additional mats or cables.

Programmable Thermostat for Underfloor Heating (Dual Voltage)

Best for flexible voltage setups and varied heat zones, this dual-sensing thermostat includes air and floor sensors with a built-in GFCI. It’s suitable when a broad compatibility with different floor materials and power supplies is needed. Note: installation may require careful wiring to match your system’s voltage.

Buying Guide

Key purchase considerations help ensure you pick the right wireless thermostat for underfloor heating:

• Size and area coverage: Match the kit to your room size. Larger rooms often require mat kits or multiple zones.
• Sensor type and placement: Floor sensors provide accurate heating control; air sensors respond to room temperature.
• Power and voltage compatibility: Verify voltage compatibility (120V vs dual voltage) with your home wiring.
• WiFi and smart-home integration: If you want remote control, choose a model with reliable WiFi or app support.
• Safety features: GFCI protection reduces electrical shock risk; look for thermal cutoffs or alarms in the kit.
• Installation considerations: Some kits require uncoupling membranes or specific tile substrates; others are mat-based for faster setup.
