Frequently Asked Questions
Do space heaters cause condensation?▾
Kerosene and propane heaters release water vapor and worsen dampness. Electric heaters (all 5 in our list) don't add humidity — they warm walls, which raises dew point and reduces condensation.
How many watts do I need?▾
Rule of thumb: 10 watts per square foot. A 150 sq ft bedroom needs 1,500 W. A 300 sq ft living room needs a whole-room infrared like the Dr Infrared DR968.
Are space heaters safe overnight?▾
Only modern models with tip-over shutoff, overheat protection and cool-touch housing (Dr Infrared, De'Longhi). Never use extension cords. NFPA reports 1,700 US home fires per year from space heaters.
Oil-filled vs. ceramic vs. infrared?▾
Oil-filled = silent, even, slow (bedrooms). Ceramic = fast, moderate noise (offices). Infrared = whole-room, radiant (large open spaces). Wall-mounted (Cadet) = permanent, code-compliant.
