When choosing from the best electric heating systems you should keep in mind the usual things like costs and the size of the floors, but there are a few particularly important factors to consider that include:

Energy efficiency – how much is this system going to cost you to use – bearing in mind you may be using them for decades?

Heating Controls – will the system afford you the range of control you would like to have with your heated floor?

Installation Requirements – are you planning on installing this system yourself? If so, is the system you are considering viable for that, or is it going to require professional installation?

Quality and Warranty – take the time to research the products. Radiant floor heating is a long-term commitment, so you need to be confident in the quality of construction. Read as many customer reviews as you can, if possible speak to people you know that have had them installed, and make sure the system comes with a good warranty.

The 5 Best Electric Radiant Floor Heating Systems For Under Tiles

STEP HEAT Radiant floor heating mats are a clear winner when it comes to radiant floor heating under tiles. 

It works using advanced automated carbon polymer heating technology and because it uses a Safety Extra Low Voltage (SELV) power supply you can be totally confident using this under tiled floors in bathrooms and wetrooms with totally assured secure usage.

The other major plus point that makes this the best electric floor heating system under tiled flooring is the improved coverage it provides when compared to alternative radiant underfloor heating systems. 

Other radiant underfloor systems typically offer only 2%-5% floor coverage, which means they have to run hotter to reach an equivalent room temperature. STEP HEAT has typical floor coverage of between 50%-60%, meaning you need to you less electricity, saving you money and being better for the environment.

5. TempZone™ Flex Rolls from Warmly Yours

TempZone flex rolls

TempZone Flex Rolls make up the final place on our list.

Whilst this product shares many similarities with other electric radiant floor heating systems we have featured, no other company has the reputation for great customer service and going the extra mile than Warmly Yours.

TempZone Flex Rolls are available in both 120V and 240V, featuring a low-profile, 1/8″ cable affixed to a mesh fabric backing in a serpentine pattern to evenly distribute heat over the entire floor.

Each cut-and-turn roll is 1′ 6″ x 49′, providing coverage generating 15 watts per square foot. 

Regrettably, Warmly Yours has decided to be one of those companies that demand you buy additional products separately, just so you can make this one work, in this case, the thermostat.

So after you’ve paid (let’s just call it $1000 to keep things simple) for your electric floor heating system, you are then presented with the news that you must pay an additional $150-$355 if you want to have the privilege of actually using it.

Anyway, apart from that, this system is definitely worthy of your consideration.


$829 – 69 square feet. (plus thermostat $159-$355)

Can electric underfloor heating go under tiles?

Yes. You have to make sure any system you are considering can go under tiles, but many of them, if not most, can. For further details take a look at our blog Electric Heating For Tile & Stone.

How much does it cost to install a heated floor under tile?

The cost of electric radiant floor installation will vary according to many factors. 

As a general rule of thumb, for a hydronic radiant underfloor system, you can expect to pay anywhere between $6 and $20 per square foot. 

For an infrared radiant electric underfloor system, you will generally pay between $8 and $15 per square foot.

Do you need special floor tiles for underfloor heating?

No, you can use pretty much any kind of tile with underfloor heating but the best tile for radiant floor heating is ceramic, closely followed by porcelain, and natural stone.

How long before turning on electric underfloor heating after tiling?

In most cases, you won’t have to wait any longer than 2-7 days before you can start using the underfloor heating for your newly tiled floor.

Always consult the tile manufacturer’s instructions to ensure it is safe to operate your new underfloor heating without risk of damage to the tiles.

One to Avoid

Warmth Technology Underfloor Heating Mat

warmth underfloor heating mat

Our “one to avoid” is the underfloor heat mat from Warmth Technology.

This is due to very flimsy and thin heating cables and a product with overall poor construction in everly element. 

It looks and feels like it has been made on the cheap and it simply isn’t up to the task.


If we had the choice of any system without restrictions, the best electric radiant floor heating under tiles would be the Step Heat Radiant Heat Mat System.

Quite simply, it has the best tech, is the most versatile, is the easiest to install and it provides great heat with excellent energy efficiency. 

However, it may not be the best option for people that are operating with a limited budget, in which case they might be better served by Warming Systems Mats or Quiet Warmth.
