Frequently Asked Questions

Are energy efficient space heaters cheaper to run than central heating?

Yes they can be cheaper if used to heat only the room you occupy. Central heating heats the whole house which often uses more energy. Zoning your heat saves money on utility bills during winter months.

How many watts do I need for a 200 square foot room?

A 1500 watt heater is typically sufficient for a 200 square foot room. This provides about 5 watts per square foot which is the standard recommendation. Check the manufacturer specs for exact coverage guidelines.

Can I leave my space heater on all night?

It is not recommended to leave heaters unattended for long periods. Use units with auto shut off timers and safety features. Always follow the manufacturer guidelines for overnight use.

What is ECO mode on a space heater?

ECO mode automatically adjusts heating power to maintain a set temperature efficiently. It reduces energy consumption by cycling on and off as needed. This helps lower electricity bills without manual adjustments.

Are ceramic heaters better than infrared?

Ceramic heaters warm air quickly while infrared heats objects directly. Ceramic is better for general room warming while infrared is ideal for targeted personal heat. Both are energy efficient depending on your needs.

Do I need a special outlet for a space heater?

Most space heaters plug into standard 120 volt outlets without special wiring. Avoid using extension cords to prevent overheating and fire hazards. Plug directly into a wall outlet for safe operation.
