Our Verdict
This is a replacement heater for a kotatsu table. It warms the small enclosed space under the table, not a room. You need an existing kotatsu table frame for it to work.
At 400W, this unit produces about 1,365 BTU per hour. That warms your legs and feet under the table. It cannot heat a full room.
The quartz tube reaches working temperature in 10 to 15 seconds. The control knob adjusts heat output. It plugs into any standard 120V US outlet.
It has no tip-over or overheat protection. Most heaters at this price include both. This is a real gap for a $129.99 product.
What We Like
- Heats up in 10 to 15 seconds after you turn it on.
- Uses only 400W, which costs far less to run than a standard 1500W heater.
- Temperature control knob lets you adjust heat to your comfort level.
- Compact 11.5 x 11.5 x 2-inch size fits under most kotatsu table frames.
- Resin housing protects the heating element and power fuse to reduce fire risk.
What Could Be Better
- 400W output is too low to heat any room. Most space heaters use 1500W.
- No tip-over protection. Most competing heaters include this safety feature.
- No overheat shutoff. Competitors in this price range typically include automatic cutoff.
- No timer function. You cannot set it to turn off automatically.
- $129.99 is a high price for a 400W single-purpose replacement unit.
