We Spent 3 Weeks Testing 24 Portable Heaters To Find One That Will Keep You Warm This Winter 2025
Nighttime cold can quickly make your home uncomfortable—and lead to higher energy bills or uneven warmth. While many portable heaters promise fast, efficient heating, finding models that truly deliver consistent comfort without excessive noise or safety concerns is surprisingly challenging.
That’s why we set out to personally test 24 of the most popular portable heaters on the market to find which offer the best combination of heating performance, safety, and value.
We tested 24 portable heaters from brands like UltraWave, Honeywell, Pelonis, TaoTronics, and Vornado. After months of real-world use, we selected the top five options based on these essential criteria:
Heating performance and efficiency
We measured how quickly and evenly each heater warmed a standard room, and tracked energy consumption to evaluate efficiency.
Safety features
Heaters should have reliable safety mechanisms such as overheat protection, tip-over shutoff, and cool-touch surfaces. We tested each model’s safety in typical household conditions.
Noise levels
Quiet operation is key for bedrooms and offices. We assessed how much noise each heater produced during normal use.
Build quality and durability
Portable heaters must withstand regular handling and transport. We examined materials, construction, and resistance to wear and tear.
Ease of use and controls
Simple, intuitive controls with adjustable heat settings, timers, and thermostats make daily use easier. We tested the user interface and overall convenience.
After 3 months of testing and reviewing, here are the top 5 portable heaters that deliver reliable warmth and comfort without compromise:
