Electric Radiant Floor Heating Reviews

As we mentioned above, there are two main types of radiant floor heating systems, but what we reviewed here are electric ones.

1. HeatWave 25 Sq. Ft. Electric Floor Heating—Best Overall

As an Amazon Associate I earn from qualifying purchases. Last update on 2024-06-24 at 08:45

This HeatWave option is a 25 square-foot heating mat that’s 20 inches in width and 15 feet long, making it larger than an average model.

It comes with a seven-day 120V programmable thermostat, providing complete automation and a powerful thermostat.

One of the most striking parts of this model is its ultra-thin profile. This makes it ideal for various types of floors, especially tile or stone. The thin profile also prevents protrusions. This is due to the easy-to-attach sticky backing that’s as simple to detach and reposition.

Apart from this, one of its other best features is that it’s extremely easy to install. You only need to apply pressure from your palm to firmly secure the mat onto any flooring.

Additionally, this model takes less than 30 minutes to heat most spaces, making it one of the most efficient models featured on our list.

Despite the positives, customers mention that the thermostat can be tricky to use.


  • Ultra-thin profile.
  • High-quality heating cables.
  • Compatible with wet locations.
  • 20-year limited lifetime warranty.


  • Customers mention that the thermostat isn’t straightforward.

2. HeatWave 120V 20 Sq. Ft. Mat Kit Electric Radiant Floor Heat Heating System—Best Thin Profile Option

As an Amazon Associate I earn from qualifying purchases. Last update on 2024-06-24 at 08:45

This 20 square-foot flooring kit has a 1/8th-of-an-inch profile, making it one of the thinnest profiles available. 

Thanks to this profile, it prevents the floor from rising, keeping your flooring within normal parameters. You won’t experience abnormal elevation as you switch between rooms with the floor warming system and those that don’t.

Attaching the mats is also extremely easy, thanks to the adhesive on the back panel. Normally, you’d have to staple them together. 

You’ll also find an AUBE sensor and thermostat included, making it programmable and providing floor-sensing capabilities. This is a one-time setup system that perfectly manages the floor’s heating.

The one drawback of this model is that the adhesive only sticks to thoroughly clean floors. Make sure to do this before you install it.


  • Lays flat and stays stuck to the floor.
  • AUBE floor-sensing thermostat and sensor.
  • Heats a 150 square-foot space with a single thermostat.
  • 25-year warranty.


  • Adhesive on the back panel only works well with clean surfaces.

3. SunTouch WarmWire (120V) Floor Heat Kit—Best Premium System

As an Amazon Associate I earn from qualifying purchases. Last update on 2024-06-24 at 08:45

Our electric radiant floor heating reviews wouldn’t be complete without this state-of-the-art selection. It’s a high-tech premium heating system that features a programmable thermostat with touchscreen operation for ease of use.

It also uses dual wire technology to reduce the electromagnetic fields to ultra-low levels. This makes it an energy-efficient unit, capable of heating your floors in double-quick time. 

Also, the use of high-quality copper as the core component is ideal for this product. It makes it inexpensive to maintain in the long run, highly durable and tough.

On top of this, it has a single-point power connection, allowing you to create the layout and wiring with relative ease.

Note that this product is available in 70 square foot cables that can fit most flooring types and dimensions.

One drawback worth considering is that the adhesive only works well on floors that have been thoroughly vacuumed. The slightest bit of dirt makes the adhesive ineffective, so remember this before installation.


  • Energy-efficient model.
  • UL listed.
  • Includes a touchscreen thermostat.
  • Single-point power connection.
  • 25-year warranty.


  • Adhesive only works on surfaces that have been well-vacuumed.

This 70 square-foot Seal model is a 120-volt variant, making it ideal for mid-sized to large rooms. The self-adhesive feature makes it compatible with a wide range of flooring options, including ceramic, tiles and mortar flooring. 

It’s a high-quality model with shockproof heating elements. This means you won’t have to worry about any stray bits of electricity finding their way towards your children or pets when the heating is on.

The thin-profile 1/8th of an inch mat is compatible with multiple flooring configurations and is easy to install. This is due to the user-friendly self-adhesive underfloor heating mat, which has simple installation instructions.

It also has twin conductors encased in a Teflon coating and includes a braided armor design. This improves the product’s long-term durability and longevity.

In contrast, the 10-year warranty is a pretty big drawback worth considering.

  • Ideal for retrofitting and new constructions.
  • Shockproof and fire retardant.
  • Self-adhesive mat.


  • No compatible thermostat included.
  • Only a 10-year warranty.

This is yet another high-quality product that’s available at an affordable price range. It certainly deserves a spot on our radiant floor heating reviews owing to this factor.

The advanced ink technology design makes it ideal for all floating floors, such as engineered wood, floating laminate, floating tile floors, cork, bamboo and vinyl.

Additionally, this is one of the easiest models to install; it just takes four simple steps.

It’s also one of the most energy-efficient models out of the ones we’ve reviewed, utilizing just 12 Watts to heat the floor.

Aside from the positives, customers pick out the thermostat is an issue—it certainly needs an upgrade.

Also included is an easy-to-install and operate AUBE thermostat. This is a high-precision thermostat that offers unparalleled control, allowing you to precisely monitor your floor’s heating levels.

The fact that this model has a less-than-ideal quarter-of-an-inch profile should be on your radar. Customers find this tricky to use.

On top of this, note that this product will raise your flooring by a quarter of an inch, so bear this in mind in planning.

Radiant Floor Heating System Buyers’ Guide

Keep these factors in mind when deciding on an electric radiant floor heating system:

Size of Your Space

You’ll need to cover your flooring’s entirety to make sure the floor heaters work efficiently.

This can be a lot of work, not to mention being expensive. Thus, it’s crucial to take your time and only choose an option covering your exact area.

Too large, and you’ll be overheating and overpaying. Too small, your space won’t be efficiently heated.

All the products featured on our list belong to three major ranges:

  • 70 square feet.
  • 25 to 30 square feet.
  • 8 to 15 square feet.

The SunTouch WarmWire is a prime example of the 70 square-foot wiring. The HeatWave Floor Heating Cable is a great product in the 8 to 15 square-foot range.

System Types

There are two primary types of radiating heating systems based on design and function:

  • Hydronic.
  • Electric.

Hydronic systems are far less expensive than electric floor heaters. They’re also far easier to install. If your house is also running on a hydronic system, it makes sense to pick up another heating system in the same category.  (You may also like to know more about hydronic baseboard heater.)

However, if you’re looking to upgrade to your current system, go for electric floor heaters. They can be far more consistent in the long run as electricity is better for consistent heating than water.

Even the heating is superior to hydronic heaters as water doesn’t compare to the proficiency of electricity. This makes these products more expensive, which is something worth considering before making a purchase.

Benefits of Radiant Floor Heating

Heat Controllers

The device’s heat controller directly dictates the quality and consistency of your heating.

It’s quite common to find thermostats included in the mat so that you can control the heating and ensure it turns off automatically. 

We suggest you pick an electric floor heating system with a programmable thermostat so that you can set varying temperatures based on different family comfort levels.

An example of a quality thermostat is the AUBE thermostat and sensor found in the HeatWave 20 Sq. Ft. Mat Kit.

Warranty Period

It’s no secret that floor heater can be challenging to maintain. Therefore, it makes sense to grab a heating system with a hefty warranty period—preferably of a decade or more.

This will save you a lot of trouble and expenses in the long run. Such systems may be more expensive than models with two to three years of warranty, but they’ll cut down on operational and maintenance costs over time.

Most of the products featured on our list come with a 20 or 25-year warranty, including the QuietWarmth 30 Sq. Ft. Electric Floor System. Only the Seal 70 Sq. Ft. 120V Radiant Floor Heating Mat comes with a 10-year warranty.


Do Heated Floors Use a Lot of Electricity?

No, heated floors do not use a lot of electricity. On average, electric floor heating systems use 12 Watts per hour per square foot. Thus, a 100 square-foot home would utilize 1200 Watts of power each hour. This is less than the power consumed by your average radiant space heater.

What Is a Good Temp Setting for Electric Radiant Heat Floor?

A good temperature setting for electric radiant heat floor is between 85 and 125 degrees Fahrenheit. This is a reference range, and it changes from to home and individual to individual.

How Long Do Heated Floors Last?

A high-quality heated floor system can last more than a couple of decades, easily. They’re far more reliable than normal furnace heaters.

The Floor is Lava

When it comes to examining the best in floor heating systems, it makes sense to not compromise on quality. This is why we recommend the HeatWave 25 Sq. Ft. Electric Floor Heating. It’s a high-quality system built by a reliable brand that’s powerful and competent enough to last a considerable period.

If our top-rated product doesn’t suit you, have a look at the HeatWave 20 Sq. Ft. Heating System or the SunTouch WarmWire (120V) Floor Heat Kit. Both feature high-quality, state-of-the-art systems and provide you with essential features, such as a programmable thermostat.
