BOWSEN Programmable Thermostat for Underfloor Heating
The BOWSEN thermostat supports both 120VAC and 240VAC, with a maximum 15A current and up to 3600W at 240V. It includes a floor sensor and an air sensor, plus a built-in GFCI for electrical safety. This model is best for safety-focused buyers who want a straightforward, dual-voltage option for standard underfloor heating setups. A potential limitation is reliance on side-access GFCI toggles and menu navigation for safety testing, which may require careful setup and periodic checks.
SunTouch SunStat CommandPlus Touchscreen Thermostat
The SunStat CommandPlus offers a 4.3″ touchscreen, remote access, and floor plus air sensing control. With a 7-day programmable schedule, energy monitoring, and weather integration, it’s well-suited for tech-forward homes seeking convenient control from anywhere. Choose this if you want strong app-based functionality and proactive energy use insights. A consideration is that features and reliability rely on Wi-Fi stability; without connectivity, some smart features won’t function optimally.
Honeywell TH115-AF-GA/U Radiant Floor Thermostat
Honeywell’s TH115-AF-GA/U is a 7-day programmable line-voltage thermostat with a floor sensor and GFCI. It’s a solid pick for traditional installations, offering reliable performance and straightforward scheduling. Best for buyers who want a trusted brand with a proven interface and no need for wireless features. Limitation: lacks built-in Wi-Fi or mobile app control, making remote access impossible without additional hubs.

Buying Guide: Key Considerations For Your Floor Heating Thermostat
- Voltage compatibility: Ensure the thermostat supports 120V and/or 240V based on your wiring. Dual-voltage models simplify upgrades in older homes.
- Sensor type and placement: Floor sensors improve comfort by matching heat to floor temperature. Air sensors adjust room air temperature. Dual sensing provides balanced control but may require careful placement.
- Safety features: Built-in GFCI is essential in wet areas or exposed installations. Confirm test procedures and troubleshooting guidance from the manufacturer.
- Smart features: Decide if you want Wi-Fi control, remote access, app scheduling, and voice assistant integration. Consider Wi-Fi stability and privacy implications.
- Programming and learning: Seven-day or multi-period programming can optimize comfort and energy use. Adaptive or self-learning modes adjust to your patterns automatically.
- Compatibility with existing systems: Some thermostats are best paired with specific floor heating cables or mats. Check if your system is compatible with Ditra, mats, or cables.
- Display and usability: A clear touchscreen or intuitive app improves daily use and reduces setup errors. Consider display size and readability in your space.
- Installation and maintenance: Look for straightforward wiring diagrams, included sensors, and accessible test functions to maintain safety over time.
