Buying Guide
FAQs
What is the most important factor for energy efficiency in a space heater?
The most crucial factor is the type of heating technology, as it directly impacts energy conversion. Ceramic and infrared heaters are generally more efficient than older fan-forced coil models because they heat objects and people directly, rather than just the air. Look for models with programmable thermostats and multiple heat settings to avoid wasting energy by overheating a room.
How do ceramic, infrared, and oil-filled heaters compare in terms of efficiency and use?
Ceramic heaters heat up quickly and are great for small, personal spaces, providing fast, direct warmth. Infrared heaters are highly efficient for larger areas as they silently warm objects and people, similar to sunlight, without drying the air. Oil-filled radiators are the most efficient for maintaining a constant temperature in a medium-sized room over several hours, as they retain heat and cycle on and off less frequently.
What key features should I look for to save energy and money?
An adjustable, programmable thermostat is essential for setting and maintaining your desired temperature without energy waste. A timer function allows you to schedule the heater to turn on and off automatically, preventing it from running when you’re not in the room. Additionally, multiple heat settings (e.g., low, high, eco) let you choose the lowest wattage needed to stay comfortable.
How do I determine the right size heater for my room?
Check the heater’s wattage rating, as a general rule of thumb is to use about 10 watts of heating power for every square foot of room space. For example, a 1500-watt heater is suitable for a room up to 150 square feet. Choosing a heater that is too large for the space will waste energy, while one that is too small will run constantly without adequately heating the room.
Are ‘Eco’ or ‘Energy-Saving’ modes on heaters truly effective?
Yes, these modes are designed to maximize efficiency by automatically adjusting the heat output and fan speed to maintain a set temperature. The heater will cycle between a high and low setting, using less energy overall than running constantly on high. This feature is particularly valuable for maintaining a comfortable temperature over long periods, like overnight.
What safety certifications should an energy-efficient heater have?
Always look for a heater that is certified by a nationally recognized testing laboratory like UL (Underwriters Laboratories) or ETL (Intertek). These certifications ensure the product has been tested for safety hazards like fire and electrical shock. Modern safety features like overheat protection, which shuts the unit off if it gets too hot, and a tip-over switch are also critical for safe operation.
Is a higher price always a sign of better energy efficiency and value?
Not necessarily. While a higher price often correlates with better build quality and advanced features like precise thermostats, the core energy efficiency is based on wattage and heating technology. A mid-priced heater with a good thermostat and timer can offer better long-term value than a basic, cheaper model that runs continuously. Focus on features that reduce energy consumption rather than price alone.
