If your heating system isn’t quite reaching every corner of your home this winter, one of the best smart space heaters could be just the solution.

Many now come with app control and voice activation; three of the heaters I found are Alexa-compatible, making it easy to adjust the heat without leaving the couch.

And with modern safety features like tip-over and overheat protection, you can feel confident using them in any room. For more on home fire safety this winter, visit the NFPA at nfpa.org.

Best Smart Space Heaters Buying Guide

When it comes to choosing one of the best smart space heaters for your home, there are five key factors to consider to ensure efficient, safe, and customized heating.

Factor #1: Room Size

The first step in selecting one of the best smart space heaters is to pick a unit powerful enough to cover your space. A heater that doesn’t suit your room size might leave you still feeling chilly. Understanding how much space your heater needs to warm will help you select the right power level.

To find one of the best smart space heaters for your needs, follow these steps:

  1. Calculate Square Feet: Measure the room’s length and width, then multiply those numbers to get the square footage. Some of the best smart space heaters list their heating capabilities by square feet, making this easy to match to your space. (Overstock’s sizing guide can help with the process.)
  2. Determine Wattage Needs: For each square foot, estimate about 10 watts. For example, a 150 sq. ft. room would need a 1,500-watt heater, a common power level among the best smart space heaters.
  3. Convert Watts to BTUs: Multiply your total wattage by 3.41 to get the BTUs needed. For instance, our 1,500-watt heater would require about 5,115 BTUs, which ensures it meets the requirements for the space.
  4. Consider Room Layout: Rooms with large windows, high ceilings, or poor insulation may need additional heating power. Choosing one of the best smart space heaters for your room type ensures balanced warmth.

Factor #2: Safety Features

Today’s models are much safer than those of the past, but it’s still essential to look for safety features when choosing among the best smart space heaters. Safety features to prioritize include:

  • Sensors: Look for smart sensors that automatically shut off the heater if it overheats, a common feature in the best smart space heaters.
  • Tip-over Protection: Shuts off the heater if tipped over, ideal for homes with pets or kids.
  • Cord Quality: Make sure the heater has a durable, built-in cord, as extension cords are not recommended with heaters.
  • Certification: Certifications from independent testing organizations like Underwriters Laboratories (UL) or Intertek’s ETL label are standard on the best smart space heaters, providing added peace of mind.

Factor #3: Heater Type

The best smart space heaters vary by heating method, and choosing the right type depends on your needs:

  • Radiant Heaters: These heaters use infrared technology to warm objects, providing a steady, lasting warmth ideal for areas where people stay seated.
  • Convection Heaters: These heaters circulate warm air quickly, making them perfect for heating a room in minutes. Many of the best smart space heaters use this method for instant warmth.
  • Bladeless Heaters: Popularized by brands like Dyson, these heaters lack visible blades or heating elements, making them a safer option.

Factor #4: Smart Wifi Features

Smart technology is everywhere, and space heaters are no exception. Smart space heaters let you adjust settings via smartphone or smart home devices like Alexa or Google Assistant. Today, the best smart space heaters offer Wi-Fi connectivity, energy monitoring, and features such as usage reporting and compatibility with smart assistants.

Factor #5: Efficiency

Energy efficiency is essential, especially if you plan to use your heater frequently. The best smart space heaters offer programmable timers, schedules, and energy usage monitoring so you can minimize costs. By using these features, you can enjoy the warmth you need without excess energy use.
