Buying Guide
- Heat output and space: Match wattage to room size. 3kW units excel in larger rooms or colder climates, while 1.5kW models are suitable for smaller spaces.
- Installation and placement: Wall-mounted convectors save floor space, whereas portable units offer flexibility. Ensure clearances from furniture and drapery for safety and airflow.
- Power supply and voltage: Some high-wattage models require specific voltages or three-phase connections. Verify home wiring compatibility and circuit capacity.
- Thermostat and controls: Built-in thermostats with LCD displays help maintain stable temperatures. Look for programmable schedules and ECO modes for energy efficiency.
- Safety features: Tip-over switches, overheat protection, and stay-cool housings reduce risk in households with children or pets.
- Noise level: Convection and quiet operation are preferred for bedrooms and study areas. Consider units marketed as silent or low-noise.
- Durability and warranty: Metal enclosures and corrosion-resistant finishes extend life. Check warranty terms for electronics and heat exchangers.
- Maintenance: Clean air intakes and vents regularly. Some models include easy-access filters or simple service components.
- Energy efficiency: Look for features like automatic temperature adjustments and multiple heat settings to optimize energy use without sacrificing comfort.
- Applications: For garages or workshops, prefer models with reinforced housings and durable motors; for living spaces, prioritize low-noise, elegant designs.
