Buying Guide: In-Wall Radiant Heaters
- What room size and insulation matter: For spaces under 120 sq ft, a 400W convection panel can be efficient; larger rooms may require 750–1500W units.
- Convection vs infrared: Convection heats air for even warmth; infrared heats objects and people directly. Choose based on room use and occupant comfort.
- Wiring and installation: In-wall units may require professional electrical work and proper wall cavities. Ensure compatibility with existing wiring and building codes.
- Smart controls: WiFi-enabled models enable schedules and remote adjustments but rely on network stability. Consider backup controls if connectivity is a concern.
- Safety features: Look for overheat protection, thermostats, and compliant enclosures. Wall-mounted installations should have surfaces that remain within safe temperatures.
- Maintenance and warranties: Longer warranty periods and ETL/UL compliance provide peace of mind for built-in systems.
- Noise and airflow: Quiet operation is important for bedrooms and study spaces. If a unit uses a blower, verify the noise level specifications.
