Heating and Cooling — FAQ
Are space heaters safe to leave on overnight?
Only use heaters with certified tip-over and overheat protection for overnight use. Place them on flat, non-flammable surfaces away from bedding. Modern ceramic heaters with these features are designed for extended operation, but never leave units running unattended.
How much does it cost to run a 1500W space heater?
At average electricity rates of $0.14/kWh, a 1500W heater costs $0.21 per hour at full power. ECO mode reduces this by 25-30%. Running 8 hours nightly costs approximately $50 monthly, significantly less than heating an entire home.
What size room will a 1500W heater warm?
1500W heaters effectively warm 150-250 sq ft depending on insulation and ceiling height. For well-insulated rooms with 8-foot ceilings, expect 200 sq ft coverage. Poorly insulated spaces or high ceilings reduce effective range to 150 sq ft.
Do ceramic heaters dry out the air?
Ceramic heaters don't actively remove moisture like combustion heaters, but warming air reduces relative humidity slightly. The effect is minimal compared to central heating. Use a humidifier if you notice dryness, especially in winter months when ambient humidity is already low.
What's the difference between oscillating and fixed heaters?
Oscillating heaters rotate to distribute heat across a wider area, preventing hot spots and warming rooms more evenly. Fixed directional heaters concentrate heat in one direction, ideal for personal warming at desks or targeted spot heating. Oscillation adds value for shared spaces.
Can I use an extension cord with a space heater?
Manufacturers strongly advise against extension cords due to fire risk from high current draw. If absolutely necessary, use a 12-gauge heavy-duty cord rated for 1875W minimum, fully uncoiled, and never exceed 6 feet length. Direct wall outlet connection is always safest.
