Radiant floor heaters are gaining traction, partly because of their space-saving design and partly because of their efficient heating. If you want your living spaces to feel warm and cozy, warm flooring is hard to beat.
Unlike other indoor heating equipment, a radiant floor heater does not need a dedicated area of the room. It installs under the floor tiling and gives off clean, invisible radiant heat that warms the floor and the space above it. Because that heat rises evenly from the whole floor, the temperature is much more even across the room, and there is no moving air to blow dust and allergens around.
With so many makes and models available, picking the right one can feel like a chore. Below we compare six popular electric floor heating mats and cable kits, from compact bathroom mats to smart-thermostat kits for large floors, and then walk through everything you should know before you buy.

2. Warming Systems 50 Sq Ft Radiant Floor Heating Cable Kit
Instead of a mat, this kit uses a loose heating cable on a spool, laid out with the included guides about three inches apart. That flexibility makes it the best choice for rooms with angles, alcoves and awkward corners, and the WiFi-enabled programmable thermostat with voice control rounds it out as the most complete package here.

Our Verdict: The best all-rounder here: enough coverage for most bathrooms, a flexible layout, and a smart thermostat that most of the cheaper kits lack.
3. SunTouch WarmWire CommandPlus WiFi Floor Heating Cable Kit (70 Sq Ft)
SunTouch’s WarmWire kit covers up to 70 square feet with a heating cable that installs over plywood, backerboard or a concrete slab.

4. SunTouch TapeMat Electric Radiant Floor Heating Mat
The TapeMat is SunTouch’s open-weave heating mat with double-sided tape along the edge, built to be rolled out, cut with scissors and set directly into thin-set mortar or a self-leveler. It heats tile, stone and laminate floors and comes in many sizes, so you can match it closely to the area you need.

- Needs thin-set or self-leveler, which means a more involved install
Our Verdict: A solid, brand-name mat when you already have a thermostat in mind, but the all-in-one kits are the simpler deal for first-time buyers.
5. Heatwave 15 Sq Ft Electric Floor Heating Kit
Heatwave’s 15 square foot kit bundles an adhesive-backed mat with a 7-day programmable GFCI thermostat and floor sensor, so everything you need is in one box. It is built for small to medium rooms like bathrooms and kitchens, and it is designed to be a manageable do-it-yourself project.

6. ThermoSoft ThermoTile Electric In-Floor Heating Mat
ThermoSoft’s ThermoTile mats use fiber heating wires with self-limiting overheat protection and four layers of insulation, including a tough nylon outer layer. The mats come in several small sizes, so they are a sensible way to warm a compact patch of tile such as a toilet nook or a short vanity run.
- Zero EMF, no interference with household electronics
- Self-limiting fiber heating wires for overheat protection
- Four insulation layers including a nylon outer layer
- Made in the USA, UL listed, 10 ft lead wire
- Self-limiting wire adds a layer of overheat protection
- Rugged four-layer insulation resists acids, alkalis and abrasion
- Several small sizes make it easy to heat a tiny area
- Made in the USA and UL listed
- Sold without a thermostat, so budget for one separately
- The small sizes are not meant for a whole bathroom floor
Our Verdict: A smartly engineered, affordable mat for tiny spaces, though you will need to add your own thermostat and it will not heat a full room.
Radiant Floor Heater Buying Guide
Choosing a radiant floor heater that fits your needs can be a challenge. This guide explains the factors that matter most so you can pick the right system for your room, your floor and your budget.
What Type of Radiant Floor Heating Is Right for Me?
Radiant floor heating comes in three types: electric, hydronic and air-heated, each with its own strengths.
Electric floor heating has a low installation cost and is easy to build into the floor. Many electric systems come as mats that sit on the subfloor, which makes them a natural fit for bathrooms and kitchens. In cold climates, electric systems can cost more to run, so a floor with good thermal mass, such as tile, helps hold the heat.
Hydronic floor heating uses warm water in tubes under the floor. It gives very balanced heat and is economical to run, but it has a high installation cost and needs a boiler. If your home does not already have a boiler, adding one raises the cost considerably.
Air-heated floor heating is rare. It works best alongside a solar source and is typically used where heat is only needed during the day.
Electric vs. Hydronic
Electric and hydronic are the two most popular systems. An electric system uses heating cables or mats and plugs into your home’s electrical supply, either through a socket or a direct connection. It is easy and straightforward to install, especially in a single room. A hydronic system relies on connecting to your home’s hot water heating, which makes it cost-effective to run over time but much more involved to install. For a single bathroom or kitchen remodel, electric is nearly always the practical choice.
Size
Think carefully about the area you plan to heat. A system can warm a single room or a whole house, but the size of the heater should match the floor area you want heated, and costs rise with size, especially for electric systems. If the floor is irregular, a cable system or a mat that can be cut and turned is a great option.
You can also use zone heating, splitting the system into sections with separate thermostats and timers so different rooms hold different temperatures. That makes the whole setup easier to control and more energy efficient. If you plan to install it yourself, follow the manufacturer’s manual carefully when laying the wires.
Heat Controllers
A good thermostat or controller is essential. It adds safety by shutting the heater off when the floor or the surrounding area gets hotter than the set level. Check whether a kit includes one, because some mats are sold without. Touchscreen models give precise control, and many now offer WiFi or voice control.
A programmable thermostat or timer is especially useful, because it lets you have a warm floor waiting when you get up in the morning instead of waiting for it to heat. With a programmable model you can set different temperatures for different times of day.
Flooring Type
The flooring above the heater matters a lot. Ceramic tile is the classic choice: it is a good thermal conductor, it warms up quickly and it holds heat for a long time. Wood, vinyl and carpet can also work. If you choose wood, use solid or engineered wood that is rated for radiant heat, because the floor expands and shrinks with temperature changes; soft woods can split. If you choose carpet, pick one with a thin underlay so heat can pass through easily.
Remember that the thicker the floor covering, the less efficient the heating. Adding laminate on top of the heater, for example, reduces the warmth you feel, so keep the covering as thin as practical for better results.
Obstacles
Think about what will sit on the heated floor. Sofas, bookcases and in kitchens cupboards and appliances can trap the heat and waste it. Skip areas under permanent fixtures such as kitchen units and bathroom furniture; this saves both energy and installation cost. If you move furniture around often, it is fine to heat the floor beneath it.
How Does Radiant Floor Heating Work?
In a radiant system, a heating element is placed under the floor and covered with the finished flooring, such as tile, vinyl, carpet or laminate. When it is switched on, heat from the electric wires or hydronic tubes passes through the floor into the room. The main advantage is that it delivers uniform heat throughout the space. It is also a cost-effective way of heating, and even more so in a new build where the floor is not finished yet. It is possible to install a radiant system over a hollow floor, but that needs insulation underneath and is harder to do.
What Makes Radiant Floor Heating So Cozy?
First, the heat is uniform, and the floor can be warm enough to walk on barefoot, which is lovely on a cold winter morning, especially in a bathroom. Second, the air stays more comfortable: many conventional heating systems leave the air dry and stuffy, while radiant heat does not dry it out in the same way.
Does Radiant Floor Heating Make Any Noise?
No. Both hydronic pipes and electric mats operate silently, with no moving parts. A hydronic system can produce a faint hiss from air in the system or a little noise from the boiler, but it is far too slight to be a disturbance.
How Much Do Heated Floors Cost per Square Foot?
The cost depends on the type of system and on how it is installed. Electric mats and cable kits are generally the most affordable to buy, with the total cost of a project rising with floor area, the thermostat you choose and any professional installation. Using a programmable thermostat and heating only the areas where you need warmth helps keep running costs under control.
Can I Install Radiant Floor Heating Myself?
It is possible to install a radiant floor heating system yourself, but you should first check local permitting requirements and building codes. Some jurisdictions require proof of insurance for the work. Because the system must be wired correctly, it is often wise to hire a professional, or at least have an electrician make the final connection.
