Choosing between a 120V vs 208V space heater depends on your home’s electrical infrastructure and layout needs. Both units are hardwired Stelpro models designed for silent operation and require external thermostats. The main difference lies in their power source and form factor. One unit uses standard 120V circuits for baseboard mounting, while the other relies on 208V systems for ceiling installation. Your choice will depend on available wiring and where you want to place the heat source.

Which one should you choose?
Choose Stelpro Brava 48-Inch 1000W Baseboard Heater if
- You have standard 120V circuits and want silent convection heat without moving parts.
- You need to cover a larger area of up to 100 sq ft with a baseboard unit.

Choose Stelpro 750W 208V Ceiling Heater if
- You have a 208V circuit and want instant heat distributed by a fan.
- You need to free up wall space with a discreet ceiling-mounted design.
- You want heat thrown up to 8 ft away for even distribution in smaller rooms.
Verdict: Choose the 120V baseboard heater if you prioritize silent operation and higher wattage for slightly larger spaces.

120V vs 208V Space Heaters in 2026: Key Differences
Voltage and Power
The Stelpro Brava 48-Inch 1000W Baseboard Heater operates on a 120V circuit, delivering 1000W of heating power. This configuration allows it to cover up to 100 square feet of space. In contrast, the Stelpro 750W 208V Ceiling Heater is designed exclusively for 208V circuits. It provides 750W of output, suitable for rooms up to 75 square feet. You must ensure your electrical infrastructure matches the specific voltage requirement of your chosen unit. The 120V model offers higher wattage, while the 208V unit is limited to lower power output.
Form Factor
Installation style differs significantly between these two heaters. The Brava is a baseboard unit, measuring 48 inches in width and 5.75 inches in height. It mounts low on the wall, blending with trim and protecting children with rounded corners. The ceiling heater is a compact, discreet unit with dimensions of 16.5 inches in width and 4.94 inches in height. It mounts to the ceiling, freeing up valuable wall space. This makes the ceiling model ideal for bathrooms or entryways where floor space is limited. The baseboard model is better for standard living areas.
Heating Method
Heat distribution varies based on the internal components. The Brava baseboard heater uses silent convection with a tubular stainless steel sheathed element and aluminum fins. It warms up and cools down without the ticks and pops common to other units. The ceiling heater uses a nichrome element and includes a fan. It produces instant heat and distributes it with an airflow of 60 CFM, reaching up to 8 feet away. If you prefer silent, passive warmth, the baseboard is better. If you need rapid, forced-air distribution, the ceiling unit is the choice.
Control Method
Both units require external control and do not include built-in thermostats. You must purchase a wall thermostat separately to operate either heater. For the Brava, you can choose between electronic or mechanical models, such as the SIBTE12F or SIBT1W. The ceiling heater strongly recommends an electronic thermostat for precise temperature management. Neither unit offers smart home integration or built-in controls out of the box. Your experience with temperature regulation will depend entirely on the quality of the external thermostat you select and install.
Build and Warranty
Both heaters feature durable steel construction with a white powder finish. The Brava is made in North America and includes a 5-year manufacturer warranty with lifetime coverage on the heating element. The ceiling heater also comes with a 5-year limited warranty, though electronic components are covered for only 3 years. The Brava weighs 9 pounds, while the ceiling heater weighs 11 pounds. Both units are hardwired and include necessary mounting hardware. The Brava offers slightly better long-term coverage for the core heating component.
Which 120V or 208V heater fits you
Homeowner with standard 120V bedroom circuit
This 120V baseboard unit delivers 1000W to heat up to 100 sq ft. Its silent convection design fits bedrooms or offices. The 48-inch steel construction blends with walls. You must install an external thermostat separately. It offers a five-year warranty and covers standard residential circuits without requiring specialized voltage.
Installer needing compact ceiling mount for 208V
This 208V ceiling heater provides 750W with a fan for 60 CFM airflow. It covers 75 sq ft with an eight-foot throw. The compact design saves wall space in bathrooms or entryways. It mounts to ceilings and requires a separate wall thermostat. The unit is hardwired to a 208V circuit only.
User prioritizing silent convection warmth over speed
The baseboard heater uses a stainless steel element with aluminum fins for silent heating. It lacks a fan, avoiding noise in quiet spaces like home offices or condos. The one-piece steel cabinet reduces ticking sounds. You get instant warmth through convection. This model suits spaces where noise matters more than rapid air circulation.

Frequently asked questions
Can I plug a 208V heater into a standard 120V outlet?
No, you cannot. The Stelpro 750W 208V Ceiling Heater requires a dedicated 208V hardwired circuit. Plugging it into a standard 120V outlet will prevent the unit from operating correctly. You must verify your home’s electrical infrastructure before installation to ensure the voltage matches the heater’s requirements.
What is the maximum wattage for a 120V space heater?
The Stelpro Brava 48-Inch 1000W Baseboard Heater operates at 1000W on a 120V circuit. This is a common maximum for standard residential circuits. It provides sufficient heat for small rooms under 100 square feet. Higher wattages typically require higher voltage sources like 208V to maintain safe current levels.
Do these heaters need a thermostat?
Yes, both units require an external thermostat. They are designed for silent operation and hardwired installation but do not include built-in temperature controls. You must install a compatible external thermostat to manage heating cycles. This ensures the room stays at your desired temperature without manual intervention.
Which heater is better for a bathroom?
The Stelpro 750W 208V Ceiling Heater is ideal for bathrooms. Its ceiling-mounted form factor saves floor and wall space. It fits discreetly in small rooms like entryways or bathrooms. If you have a dedicated 208V circuit, this unit offers a space-saving solution that blends into the ceiling.

Are these heaters portable?
No, both heaters are hardwired and non-portable. The 120V baseboard model and the 208V ceiling model require professional electrical installation. They are not designed to be moved or plugged into standard outlets. You must install them in a fixed location within your home’s electrical system.
