Buying Guide: Key Purchase Considerations
What room size will you heat? Match wattage to space: 600W units are best for small rooms, 900-1500W for medium to large spaces. Look for heaters with 7 fins for better heat distribution and longer warmth after shutdown. Is safety important? Seek tip-over protection, overheat protection, ETL certification, and sturdy construction. Do you want convenience features? Remote control, ECO mode, and programmable timers can save energy and improve daily use. How important is noise? Oil-filled radiators are typically quiet since they lack fans, making them ideal for bedrooms and study areas.
