Mysa is a high‑voltage smart thermostat specifically made for electric baseboards and fan‑forced heaters. The product supports loads up to 3800W at 240V and requires a four‑wire connection including a neutral or second live. Key listed features include Wi‑Fi connectivity, HomeKit/Alexa/Google support, adaptive display and brightness technologies, and mobile app control. The listing notes compatibility limits: it does not support two‑wire or low‑voltage systems, so verifying wiring before purchase is essential.
meross Smart Thermostat For Electric Baseboard And In‑Wall Heaters
The meross thermostat supports 120–240V high‑voltage systems with a maximum load of 3840W at 240V (16A). It is advertised as an easy install smart thermostat that integrates with Apple Home, Alexa, Google Home, and SmartThings for voice and remote control. The features emphasize energy‑saving scheduling, and the listing requires at least four wires in the electrical box. This device targets users seeking smart automation for line‑voltage baseboard or convector heaters.
Honeywell Home RLV4305A1000 Programmable Thermostat
The Honeywell RLV4305A1000 is a digital 5‑2 day programmable thermostat designed for electric baseboards, convectors, and fan‑forced heaters. The listing highlights high accuracy (±0.27°F) and TRIAC switching for silent operation and precise temperature control, which helps reduce temperature swings. Its programmable schedule capability and line‑voltage TRIAC control make it suitable for homeowners prioritizing consistent comfort and predictable runtime for 240V heating circuits where this thermostat’s wiring and load ratings are compatible.

Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes
Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors. - Negotiate Smartly
Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Voltage And Load Matching
- Confirm System Voltage: Verify whether your circuit is 208V, 220V, or 240V and select heaters and thermostats rated for that voltage.
- Check Wattage And Breaker Size: Ensure total heater wattage per circuit does not exceed the breaker and thermostat maximum load (e.g., 3840W at 240V is common for smart controllers).
Thermostat Compatibility
- Wiring Requirements: Many smart high‑voltage thermostats require four wires including a neutral or second hot. Older two‑wire baseboards may need different thermostats or rewiring.
- Load Rating: Match thermostat ampacity to the heater load. For multiple heaters on one thermostat, sum the total wattage to confirm compatibility.
- Smart Features: Consider Wi‑Fi, app control, voice assistant support, and schedule types (7‑day, 5‑2 day) depending on desired automation.
Heater Type And Placement
- Linear Convector vs Traditional Baseboard: Convector heaters like Dimplex use airflow patterns for quicker room circulation; fin or ribbon‑element baseboards provide gentle radiant/conductive heat.
- Length And Watt Density: Longer units at the same wattage distribute heat more evenly. Match unit length to room layout and mounting options (floor or wall).
Installation And Safety
- Hard‑Wiring Required: Most 240V units are hard‑wired and must be installed by a qualified electrician per local code.
- Safety Cutouts: Look for high‑temperature shutoff or safety cutout features to reduce overheating risk.
- Clearance And Covers: Maintain manufacturer‑recommended clearances and consider replacement covers to restore appearance and protect occupants from direct contact.
Energy Efficiency And Controls Strategy
- Programmable Schedules: Use programmable or smart thermostats to lower temperature during unoccupied periods and reduce runtime.
- Adaptive Thermostat Features: Adaptive algorithms (learned schedules, preheating) can improve comfort while saving energy in high‑voltage systems.
Comparison Perspectives
- Value vs. Features: Basic line‑voltage heaters provide reliable heat at lower cost; smart thermostats add convenience and potential energy savings but require compatible wiring.
- Single Unit vs System Approach: For whole‑room control, pair appropriately sized heaters with a thermostat rated for the combined load; for multi‑zone control, install separate thermostats per zone.
- Short Runs vs Long Runs: For short wall spans, higher watt density or convector units may be preferable; for long spans, standard baseboards can deliver more even heat.
