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.

5. TempZone™ Flex Rolls from Warmly Yours

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

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.

One to Avoid
Warmth Technology 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.
Conclusion
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.
