Radiant floor heating rugs and under-rug mats add warmth to a specific floor area without replacing a home’s central heating. The Woo Warmer is best for a large warm zone or under-desk use, while the 63-by-93-inch RugHeat mat is suited to larger rugs. The adjustable infrared mats offer temperature and timer controls; the 20-by-39-inch model is better for a compact personal area.

Woo Warmer Large Under-Rug Heater
The Woo Warmer is a 720-watt electric heating mat measuring 92 by 76.5 inches. Its listed purpose is to create a warm floor zone beneath a favorite area rug. The product is made with polyester and is described as suitable for use under a desk as well as for sitting or lying on.
Best for: Buyers who want broad coverage for a sitting area, a yoga space, or a desk where feet get cold. Its large dimensions make it a better fit for a larger defined zone than a small foot mat.
Why it was selected: This option directly matches the under-rug heating use case and provides a clear power rating and size in the product details.
Consideration: The listed information does not specify temperature settings, a timer, or automatic shutoff. Check the product instructions for operating and rug-placement requirements before use.
Adjustable Infrared Heated Floor Mat
This infrared floor mat is described as using graphene carbon crystal heating and a five-layer safety structure. Its features include 60 temperature adjustment levels, a 12-hour timer, thermostat control, and automatic shutoff for overheat protection. The listing also describes a waterproof layer, non-slip construction, and a design intended to be easy to clean and store.
Best for: Buyers who prioritize adjustable heat and a longer timer. The 60-level control offers more stated adjustment steps than the six-setting mat in this guide.
Why it was selected: The control options and timer make it a flexible choice for people who want to tailor operation rather than use a single fixed setting.
Consideration: The listing gives a claimed heating range of 0°F to 180°F but does not provide the mat’s dimensions. Confirm its size and follow the manufacturer’s instructions instead of assuming it will fit a particular rug.
RugHeat Extra-Large Under-Rug Mat
The RugHeat Extra Large measures 63 by 93 inches and is described as fitting beneath a 5.5-by-8-foot rug, with the listing also referencing a 6-by-9-foot rug size. The mat has an 8-foot power cord positioned at a corner. Its features describe it as portable and waterproof, with suggested use in areas including bedrooms, living rooms, kitchens, basements, and bathrooms.
Best for: Buyers heating a larger rug-covered area who want a mat with its dimensions clearly stated. It is larger than the compact mats in this group.
Why it was selected: The size guidance makes it easier to compare the mat with a rug before buying. The corner cord and stated 8-foot length may also help with placement planning.
Consideration: The product information recommends two mats for a 9-by-12-foot rug or larger. Measure the rug and intended placement; do not assume one pad will cover a larger area.
Wood-Grain Heated Floor Mat, 20 x 39 Inches
This 20-by-39-inch mat has an artificial-leather surface with a light wood-floor texture. The listing describes 60 temperature levels, a 12-hour timer, three-button controls, and automatic shutdown protection for overheating. It is also described as waterproof, oil-proof, quiet during use, and easy to clean.
Best for: A buyer who wants a compact warm surface near a desk, in a bedroom, or for a small practice area. Its narrow dimensions suit localized use better than heating a whole large rug.
Why it was selected: The product combines a defined compact size with multiple temperature adjustments and a longer stated timer. The textured appearance may suit buyers who prefer a floor-like finish over a plain mat.
Consideration: At 20 by 39 inches, it is not the choice for broad rug coverage. The stated 0°F-to-180°F range is a product listing claim, so consult the included instructions for appropriate settings and use.
Long PU-Surface Heated Rug Mat
This electric mat measures 23.6 by 74.8 inches and is listed as a 110-volt product. It has a PU surface described as waterproof, oil-proof, and easy to clean, plus a thick rubber bottom described as non-slip and protective of the floor. Its controls offer six temperature settings, a 9-hour timer, and automatic shutdown protection.
Best for: Buyers who want a long, narrower warm zone, such as beside a bed or along a work area, rather than a nearly square mat. Its listed settings and timer allow basic adjustment.
Why it was selected: The dimensions distinguish it from the larger area-rug pads and the shorter personal mat. The surface and bottom materials are clearly described in the supplied product features.
Consideration: It has six temperature settings rather than 60 adjustment levels. Check that the listed 110-volt specification and mat dimensions suit the intended location.
Buying Guide: How To Choose A Radiant Floor Heating Rug
Should you choose an under-rug mat or a surface mat?
Under-rug heaters are intended to sit beneath an area rug, making the heat source less visible. The Woo Warmer and RugHeat products are described for this purpose. Other listings describe heated floor mats or heated carpets but do not all provide the same rug-placement directions. Read each product’s instructions to confirm whether it is designed to be covered, used on top of flooring, or used in another way.
Do not decide based only on the word “rug” in a product name. A heated mat’s placement, covering requirements, and suitable floor surfaces depend on its manufacturer’s directions. This matters because the products differ in construction and the supplied features do not give identical operating guidance.
What size mat should you buy?
Measure the floor area and rug before selecting a mat. Compare the mat’s length and width with the area where you want warmth, and check whether the product is intended to fit beneath the rug. A small mat is useful for a localized spot, while a larger model can serve a broader zone.
- Compact area: The wood-grain mat measures 20 by 39 inches.
- Long, narrow area: The PU-surface mat measures 23.6 by 74.8 inches.
- Large rug area: RugHeat measures 63 by 93 inches, and the Woo Warmer measures 92 by 76.5 inches.
For the RugHeat mat, the listing recommends two pads for a rug measuring 9 by 12 feet or larger. Treat this as product-specific sizing guidance rather than a universal rule for every heater.
How important are temperature controls and timers?
Controls determine how much flexibility you have over operation. The adjustable infrared mat and wood-grain mat list 60 temperature levels and 12-hour timers. The PU-surface mat lists six settings and a 9-hour timer. The Woo Warmer’s supplied features do not state a temperature adjustment system or timer.
More settings do not by themselves establish how warm a mat will feel in a particular room. Compare the actual controls, timer duration, and operating instructions, and choose based on the level of adjustment you need. If automatic shutoff matters to you, verify that feature in the specific product details and manual.
Where will the power cord reach?
Plan the mat’s position around the nearest appropriate outlet. RugHeat lists an 8-foot cord with the connection at a corner. The other provided product details do not specify cord length, so check the listing or manufacturer instructions if outlet distance will affect placement. Avoid making a purchase decision based on an assumed cord length.
What surface and cleaning details should you compare?
Surface materials can affect the way a mat looks and how its owner cleans it. The Woo Warmer lists polyester. The wood-grain mat describes an artificial-leather surface, while the long mat uses PU. The infrared mat and RugHeat listing describe waterproof features. These descriptions are not a substitute for care directions: check the instructions for cleaning, storage, and suitable flooring.
How should you compare safety-related features?
Look for clearly stated operating features, including automatic shutoff, timer controls, overheat protection, non-slip construction, and waterproofing. Some products in this selection list several of these features, while others provide less detail in the supplied information. Do not infer a feature that is not specified. Follow the manufacturer’s placement and use directions, particularly when placing any mat beneath a rug or near moisture.
Frequently Asked Questions
Can a radiant floor heating mat go under an area rug?
Some products are specifically described for under-rug use, including the Woo Warmer and RugHeat. Confirm that any mat you choose is approved by its manufacturer for the intended placement, and follow its coverage and flooring instructions.
Which listed option is largest?
The Woo Warmer measures 92 by 76.5 inches. RugHeat measures 63 by 93 inches. Compare both dimensions with the rug and warm zone because the mat with the greatest area may not have the best shape for your space.
Which mats list a 12-hour timer?
The adjustable infrared mat and the 20-by-39-inch wood-grain mat list 12-hour timers. The long PU-surface mat lists a 9-hour timer. The provided Woo Warmer and RugHeat features do not specify a timer.
Are all heated floor mats the same size?
No. The products here range from a 20-by-39-inch mat to large mats measuring more than 90 inches in one direction. Check both dimensions and the manufacturer’s recommended rug size before ordering.
Can these mats replace a home’s central heating?
The supplied product information describes these items as ways to warm a specific floor zone or area. It does not establish that any of them can replace a home’s central heating system.
What should I check before using a mat in a bathroom or kitchen?
Check the specific product’s instructions for room suitability, moisture exposure, placement, and cleaning. RugHeat is described as waterproof and suggested for kitchens and bathrooms, but do not assume that every heated mat has the same water resistance or use guidance.
