Buying Guide
Key factors to consider when choosing a 120-volt wall heater:
- Room size and heat needs: Higher wattage (1000–1500 W) is better for mid-sized rooms; smaller spaces may be fine with 750–1000 W.
- Thermostat control: Built-in thermostats enable automatic cycling for consistent comfort and energy savings.
- Noise: Look for units advertised as quiet if the heater will be in bedrooms or study areas.
- Ventilation and safety: Check for overheat protection and automatic shutoff features; ensure clearance and installation comply with local codes.
- Wiring and voltage options: Some models support both 120 V and 240 V; verify house wiring and panel capacity before choosing dual-voltage units.
- Installation type: Recessed/completely flush or surface-mounted; recessed units save space but require precise mounting.
- Oscillation and heat distribution: Oscillating models provide broader coverage; fixed-direction heaters may heat a targeted area more intensely.
