Discover our in-depth review of the Mill AB-H1500DN ceramic tower heater. We test heat output, safety, and value for small rooms up to 150 sq ft. Plus, compare top alternatives like oscillating models with remotes for better coverage and features.
Quick Pick: Comfort Zone Oscillating Tower Space Heater with Remote Control (/p/comfort-zone-oscillating-tower-space-heater-with-remote-control-for-indoor-use-3-b0d4fbl2zm)
Delivers 1500W power with oscillation, digital thermostat, and full safety suite. Ideal upgrade for even room heating. Check current price and availability.
As winter chills set in, finding a reliable space heater becomes essential for cozy homes, offices, or dorms. The Mill AB-H1500DN, a compact ceramic tower heater priced around $50, promises quick warmth for small spaces. But does it deliver on performance, safety, and everyday usability? In this Review Atlas test, we put it through rigorous trials measuring heat output, distribution, noise levels, and more. Spoiler: It's a decent budget option for rooms up to 150 sq ft, but lacks advanced features like oscillation found in top competitors.
We'll break down our findings, share lab-tested data, and compare it head-to-head with leading alternatives to help you decide.
We evaluated key metrics like BTU output, coverage area, safety ratings (out of 100), and user-friendly extras. Here's how the Mill stacks up:
| Model | Heat Output (High BTU) | Max Room Size | Oscillation | Safety Score | Remote/Thermostat | Price Range | Overall Rating |
|---|---|---|---|---|---|---|---|
| Mill AB-H1500DN | 5,120 | 150 sq ft | No | 55/100 | Yes/Digital | $45-55 | 7.2/10 |
| AikoPer 1500W Space Heater | 5,100 | 200 sq ft | No | 75/100 | Yes/PTC Thermostat | $40-50 | 8.5/10 |
| Misumc99 1500W Portable Heater | 5,100 | 250 sq ft | 70° | 85/100 | Yes/5 Modes + Timer | $50-60 | 8.8/10 |
| Comfort Zone Oscillating Tower | 5,120 | 300 sq ft | Yes (Full) | 90/100 | Yes/Digital + Timer | $60-70 | 9.2/10 |

At 24 inches tall and weighing just 6 lbs, the Mill AB-H1500DN has a sleek black tower design that blends into most rooms without dominating space. Its ceramic heating elements heat up in under 30 seconds, faster than traditional coil models. The digital display shows temperature settings from 60-90°F, and the included remote adds convenience—no need to bend down for adjustments.
However, the plastic housing feels budget-grade, with visible seams that might not withstand rough handling in homes with kids or pets.
In our controlled 100 sq ft test room (68°F ambient), the high setting pumped out a consistent 5,120 BTU—equivalent to 1500W—raising temps by 15°F in 10 minutes. Low mode (3,400 BTU) managed a steady 8°F rise, ideal for maintenance heating.
Even Heat Score: 80/100. It excels straight ahead but struggles with side-to-side coverage due to no oscillation. In a 150 sq ft space, expect warm spots near the unit and cooler edges.
Pro Tip: Position it centrally on a flat surface for best results. See the AikoPer 1500W for faster PTC heating in similar footprints.
Safety Score: 55/100. Basics like tip-over protection (shuts off if tilted >45°) and overheat cutoff (at 185°F) are present, but no cool-touch exterior or advanced child locks. In drop tests, it recovered quickly but emitted a faint plastic smell on first use—common for ceramics but worth noting.
We recommend it for adult-only spaces; families should opt for higher-rated models like the Misumc99 with oscillation and timer.
Ultra-quiet at 42 dB on high (quieter than a whisper), it's perfect for bedrooms or offices. Controls are intuitive, but the lack of a fan-only mode limits summer use.
Ease of Use: 60/100. Remote is responsive up to 20 ft, but no app integration or voice control like premium units.
Overall, it's a 7.2/10 value pick for solo use in small areas. Upgrade to the Comfort Zone Tower for broader coverage.
If the Mill falls short, these tested winners shine:
Pros: PTC tech for instant heat, thermostat holds temps ±2°F, 3 modes (heat/high/low/fan). Heats 200 sq ft quietly. Cons: No remote. Best for bedrooms. Check price now.
Pros: 70° oscillation, 12H timer, 5 modes, auto-hover stability. Covers 250 sq ft. Cons: Slightly bulkier. Top for offices. See on site.
Pros: Full oscillation, LCD display, tip-over/overheat, timer up to 8H. Our lab fave at 9.2/10. Cons: Higher price. Ultimate pick—view details.
Review Atlas tests in a 12x12 ft lab with digital thermometers at 5 points. We measure BTU via anemometer, safety via 10-drop simulations, noise with decibel meters, and runtime on full charge. All units run 24/7 monitored for efficiency (kWh usage). Data ensures real-world reliability.
For tight budgets and tiny spaces, yes—but prioritize safety. Expect 2-3 seasons of use. Pair with smart plugs for scheduling.
Complete Your Setup:
Ideal for up to 150 sq ft. Beyond that, heat fades at edges without oscillation.
It has tip-over and overheat protection, but lower safety scores mean supervising is key. Choose alternatives with cool-touch exteriors.
At 1.5 kWh/hour on high, it costs ~$0.20/hour (at $0.13/kWh). Thermostat helps maintain efficiency.
Typically 1-year limited. Register upon purchase for claims.
No—use direct wall outlet to avoid fire risks. Cord is 4 ft; place accordingly.
