What Makes a Space Heater “Energy Efficient”?
An energy efficient space heater does more than just warm up a room, it optimizes the energy it consumes to give you the most heat for the lowest cost. But what does that really mean?
Here’s what to look for:
- Wattage-to-Heat Ratio: Look for heaters that convert more electricity into usable heat without waste.
- Thermostatic Control: Models with built-in thermostats can cycle on/off to maintain temperature, preventing overuse.
- Eco Modes & Timers: These settings allow for better control and avoid unnecessary heating.
- Directional Heating: Heaters that warm you directly (like infrared) often use less energy overall.
- Smart Features: Integration with smart home systems lets you automate and optimize usage (learn more in our Best Smart Home Devices for Energy Efficiency guide).
Choosing a model with these features ensures you’re not just staying warm, you’re doing it smartly.
