Buying Guide
FAQs
What features are most important for an efficient space heater?
Look for adjustable thermostats and multiple heat settings, which allow you to use only the energy needed. A programmable timer and an eco-mode can significantly reduce energy consumption by automatically shutting the heater off. Safety features like tip-over and overheat protection are also essential for peace of mind.
What’s the difference between a ceramic and an infrared heater?
Ceramic heaters use a ceramic element to heat a small area quickly and are great for personal use or small rooms. Infrared heaters emit infrared radiation to heat objects and people directly, making them feel warmer faster and better for larger, draftier spaces. Infrared models are often more efficient for whole-room heating as they don’t lose as much heat to air circulation.
How do I choose the right size heater for my room?
Check the heater’s wattage; a good rule of thumb is about 10 watts of heating power for every square foot of room space. For a 150-square-foot room, a 1,500-watt heater is typically sufficient. Always refer to the manufacturer’s recommended room size to ensure safe and efficient operation.
Are more expensive heaters actually more energy-efficient?
Not necessarily. While pricier models may offer better build quality, more features, and advanced safety measures, all electric space heaters are 100% efficient at converting electricity to heat. The real value in a more expensive model lies in features like better thermostats and timers that help you use the heater more intelligently, thereby saving you money on your energy bill.
How much does it cost to run a space heater?
The cost depends on your heater’s wattage and your local electricity rate. A standard 1,500-watt heater running for one hour uses 1.5 kWh of electricity. To find the exact cost, multiply 1.5 by your utility’s price per kilowatt-hour (kWh).
What safety certifications should I look for?
Always choose a heater that is certified by a nationally recognized testing laboratory like UL (Underwriters Laboratories) or ETL (Intertek). This certification ensures the product has been tested and meets strict safety standards for electrical performance and fire hazards. Features like cool-touch exteriors and tip-over switches provide an additional layer of safety.
Is it worth buying a heater with a remote control or smart features?
These features add convenience but don’t directly impact the heater’s energy efficiency. A remote control is useful for adjusting settings from across the room, while smart features allow you to control the heater via a smartphone app. This can be valuable for scheduling heating times so the room is warm when you arrive home, potentially saving energy by not running it all day.
How can I maximize my heater’s efficiency and save money?
First, only heat the room you are in and close the door to contain the warmth. Using a ceiling fan on a low, reverse setting can help circulate the hot air more evenly throughout the room. Additionally, using the heater’s timer to turn it off automatically after you fall asleep prevents it from running all night unnecessarily.
