Mysa Smart Thermostat for Electric Baseboard Heaters V2

Yes, as long as you stay within the power limits. You can wire multiple heaters in parallel to one Mysa thermostat (e.g., two baseboards on opposite walls of the same living room).
Check Your Wattage: The total power of all heaters combined must not exceed 3,800 Watts (at 240V) or 1,900 Watts (at 120V).Check Your Space: The electrical box (gang box) must be large enough to accommodate the extra wires and wire nuts needed to join the heaters together. If the box is too crowded ("box fill"), it can be dangerous. Heaters are often daisy-chained to reduce crowding in the thermostat box.

Yes. The free Mysa app gives you complete temperature control from your phone. Full control means adjusting your thermostat from bed, work, or vacation.

It depends on the product. Mysa for Baseboard is generally compatible with GFCI breakers. However, Mysa for In-Floor includes its own built-in GFCI protection and should not be installed on a circuit that is already protected by a GFCI breaker to avoid nuisance tripping.

Yes. Baseboard heaters use high-voltage (line voltage 120V-240V) power, so they need a thermostat made specifically to handle that electrical load directly. Regular low-voltage smart thermostats (like those used for furnaces or central HVAC) aren’t compatible and can be dangerous if connected to these systems.

That’s exactly why Mysa’s electric baseboard heater thermostat was created. It’s purpose-built for high-voltage electric baseboard, fan-forced in-wall, and in-ceiling heating systems. You can finally enjoy smart-home control, scheduling, and energy savings with the electric heating setup you already have!

They can, especially if they’re left running continuously. Electric baseboard heaters are 100% efficient at converting electricity into heat, but they can still be expensive to run if not managed properly. Factors like room insulation, window quality, and using a smart thermostat to minimize run time all influence monthly energy consumption.

Not always. It depends on your comfort level and local regulations. Many customers can install the smart thermostat for electric baseboard heaters in about 15 minutes using step-by-step guides. However high-voltage wiring requires strict safety guidelines. Always turn off the circuit breaker before starting. If you’re not confident, the wiring looks different than expected, or local regulations require it, you should hire a licensed electrician.

Most smart thermostats aren’t designed for electric baseboard heaters - they only work with low-voltage systems like furnaces or central HVAC. But Mysa for baseboard is different. It’s built specifically for high-voltage electric heating including baseboard, fan-forced in-wall, and radiant ceiling systems.

Mysa for Baseboard can replace most single-pole and double-pole thermostats, but it functions internally as a single-pole device. It requires a connection to both power wires (L1 and L2/Neutral) but only switches the power to the heater on one of those wires (the load wire).

For safety, first turn off power at the circuit breaker. Then, follow the step-by-step wiring instructions in the Mysa app. Once installed, restore power at the breaker and complete the pairing process in the app.

Programmable thermostats rely on manual input that often fails. Research shows 73% of owners never use the scheduling features because they are too complicated. Mysa removes this human error. Geofencing detects when you leave to lower the heat automatically, while smart schedules save 3-5 hours of runtime daily while you sleep. You save 15-26% on heating costs without touching the dial.

Customers typically save 10-26% on heating & cooling costs. Heating and cooling is the single largest energy expense in North American homes. Natural Resources Canada identifies heating as 61% of total energy use, while the U.S. Department of Energy confirms a simple daily temperature setback cuts annual bills by 10%. Whether you are cutting down a $2,000 annual energy bill or tackling a harsh Canadian winter, Mysa ensures you never pay to heat an empty house.

With a traditional dial thermostat, you must manually turn the knob until the room feels comfortable, which is often inaccurate and leads to overheating. Mysa’s smart thermostat allows you to fine‑tune the temperature digitally from the wall or your phone, set your ideal comfort level, and create weekly schedules or make quick adjustments via the app whether at home, work, or away.

Mysa requires more than two wires to function. Unlike old mechanical thermostats that work like a simple light switch, Mysa is a smart device that needs continuous power to stay connected.

The Requirement
You typically need four wires in your electrical box: Supply (from the breaker) and Load (going to the heater).

The Problem
If you only have two wires, it is a "switch loop" and Mysa will not work without rewiring. We recommend you hire a licensed electrician or contact support with a photo of your current thermostat wiring

Yes. Mysa for Baseboard requires a connection to both live wires in the electrical box (L1 and L2/Neutral) to power themselves; they cannot operate on a single conductor (two-wire) setups.

However, always ensure you count the wires in the junction box, not the wires coming from the existing thermostat. Many homes have an extra wire tucked into the wall. Mysa data shows less than 10% of installations only have two wires in the junction box

No. It is a common misconception that it is cheaper to leave baseboard heaters running constantly. It is more cost‑effective to heat only when and where you need it. Baseboard heaters allow zonal heating, so leaving them running in empty rooms wastes energy. Mysa’s smart thermostat can help you save up to 20% on heating costs by enabling zoned control, smart schedules, and geolocation features.

Absolutely! The Mysa thermostat is designed to optimize energy usage, helping you save on heating costs. With features like scheduling and remote control, you can manage your energy consumption effectively. Enjoy a cozy home while being environmentally friendly.
