Our Verdict
The Woo Warmer heats your floor from below a rug. You place it under a carpet or at your desk. It warms your feet and the nearby floor zone.
At 500W, it uses much less electricity than a standard 1500W heater. Your daily operating cost stays low. But the heat output is also far weaker.
The $229.85 price is difficult to justify. Most portable heaters with thermostats, timers, and safety features cost less. This mat offers only basic on/off function.
The missing overheat protection is the biggest concern. Heat can build up under a rug without a way to detect and stop it. This is a genuine safety risk.
The 6-hour auto shut-off adds a basic layer of protection. But with no thermostat, you get one fixed heat level. You cannot adjust or customize how warm it runs.
What We Like
- Large 70x70 inch mat covers about 34 sq ft of floor space.
- 6-hour auto shut-off turns the heater off without any action from you.
- 500W draws 67% less electricity than a standard 1500W space heater.
- Non-slip design keeps the mat from shifting under your rug.
- Plugs into any standard wall outlet with zero installation required.
What Could Be Better
- No overheat protection is a serious gap for a heater used under a rug.
- No thermostat means you cannot set or maintain a target temperature.
- 500W output is far below the 1500W standard for space heaters in this price range.
- At $229.85, this costs more than most feature-rich portable heaters.
- No programmable timer lets you pre-schedule when heating starts or stops.

Frequently Asked Questions
Common questions about Hot Carpet Woo Warmer Under Rug Radiant Floor Heater Electric Mat Electric Carpet Electric Heated Area Rug Great for Yoga (500 watt 70" x 70 inches) Made in Seattle WA
What size rug do I need to cover this mat?
The mat measures 70 inches by 70 inches. Your rug must be at least that size to cover the mat completely.
Can this heater warm an entire room?
No. At 500W, it only warms the floor area directly around the mat. It is designed for personal spot heating, not whole-room use.
Does it need special wiring or installation?
No special wiring is needed. It plugs directly into any standard wall outlet.
Is it safe to leave on all day?
The mat includes a 6-hour auto shut-off. However, it has no listed overheat protection, so you should not leave it running under a rug without supervision.
Can I use this mat without anything on top of it?
The mat is designed to go under a rug or carpet. Placing a rug on top helps hold heat and is the intended method of use.
