Space Heaters
Freestanding electric heaters that warm a room fast โ no furnace, no install, just plug in and feel the heat.
How to Choose a Space Heater (by Room & Wattage)
Size by room, not by price. Rule of thumb: ~10W per square foot.
Small rooms
~750โ1000W โ bedrooms, offices, bathrooms. See ceramic & small heaters โ
Medium rooms
~1000โ1500W โ living rooms, master bedrooms. See oil-filled & tower โ
Large / garage
1500W+ or gas โ workshops, open plans. See garage & patio โ
Add ~25% wattage for drafty or high-ceiling rooms, and always size to the smallest space you actually occupy. Look for tip-over + overheat cutoffs and a thermostat to avoid wasted energy.

Frequently Asked Questions
Quick answers โ surfaced in Google AI Overviews and chat engines.
Are space heaters safe?
Yes, when used correctly. Choose a model with tip-over and overheat protection, keep it 3 ft from combustibles, never run it while sleeping in an unattended room, and plug directly into a wall outlet (not an extension cord).
What size space heater do I need?
Roughly 10W per square foot. A 150 sq ft bedroom needs ~1500W; a 100 sq ft office ~1000W. Oversizing wastes energy and can trip breakers โ match watts to the room you actually occupy.
Ceramic vs oil-filled radiator: which is better?
Ceramic heats up fast and is light/portable; oil-filled radiators warm slowly but hold heat and run silently โ best for overnight bedroom use. Pick ceramic for quick bursts, oil-filled for steady, quiet warmth.
Are space heaters expensive to run?
They cost about the wattage ร your electricity rate. A 1500W heater at $0.15/kWh runs ~$0.22/hour. Use a thermostat and zone-heat one room instead of the whole house to save.
Can I leave a space heater on overnight?
Only models rated for unattended/continuous use with certified safety cutoffs, placed on a hard surface away from bedding. Many users prefer oil-filled radiators for low, steady, silent night warmth.
