Please keep in mind that you must check your electric floor heating system with a digital ohmmeter in conjunction with a Circuit Check™. Take an initial reading as soon as you take the product out of the box to verify that it is within -5% / +10% of the values stated on the product’s label. This will give you a basis of comparison for future readings. Take a second reading once you have positioned the system to match your custom installation plan. It is also advisable to take an additional reading in the middle of the tile installation, just to make sure that the Circuit Check™ is doing its job. Then, take a final reading when you are finished with the floor installation and are ready to hook up the thermostat.

The Circuit Check™ is a tool developed by WarmlyYours to give you peace of mind and ensure trouble-free installations. Simply hook up the cold leads to the tool while you position the system to match your custom installation plan.

The Circuit Check™ will continuously monitor the continuity of the circuit during the installation of your system and during the installation of your flooring. The Circuit Check™ beeps immediately when a short in the system is detected, alerting you to a potentially damaged cable in the area you are working, before you lay the tile over the electric floor heating system.
 The WarmlyYours technical support team is available 24/7 to provide assistance if the alarm sounds, or if you would have any questions during your installation.

Yes, in most cases, an electric floor heating system can be effective as a primary heat source. However, our TempZone™ and Environ™ systems are most commonly used as a secondary heat source, providing floor-to-ceiling radiant heat to any room in your home where you desire more warmth and comfort.

If you are considering electric floor heating for an addition to your home, such as a sunroom where you have no other source of heat, WarmlyYours offers an innovative online tool which calculates approximate heat loss. This tool can help you to determine if a WarmlyYours’ electric radiant floor heating system will provide your desired comfort temperature throughout the year. You can access the Heat Loss Calculator or you can call us at (800) 875-5285 and a Customer Service Representative will make the calculation for you.

A floor heating system can work as a supplemental heating source and make the basement warmer. If more heat needs to be added to the room, you can experiment with setting the floor heating thermostat to higher temperatures.

Main heat source for small bathroom

Pam G., Calgary, AB on 02/03/2025

I needed an easy heat source for a small bathroom, and chose in-floor heating from WarmlyYours. I have no experience with in floor heat, so I was very happy with the customer service I received, they were quick to answer my questions and I felt very 'looked after' with my purchase. I'm happy with my purchase, and it has been working great!

Replacement Thermostat for electric floor heat

Nils H., Lamoine, ME on 01/04/2025

Shipped promptly. Instructions shipped with thermostat clear and complete. Amplified by links to videos which were also comprehensive. Only problem I had was on my end: wires from house current feed and floor too short (kept pulling out of unit when inserted into wall box). Problem solved by using additional short pieces of wire between thermostat and house and floor wiring.

Very friendly and informative customer service and sales representatives.

Anonymous, Richmond Hill, ON on 12/27/2024

I received the support I required during the installation process. The customer service representatives were available to answer any and all questions.

It’s all about the people

Timothy S., Chillicothe, OH on 12/09/2024

The thermostat that I ordered was easy to install and works perfectly. Jeff Burnett returned several emails and even called me. When I placed my order on the website instead of calling to get a discount, the phone rep corrected my mistake instantly. Such attentive service for a relatively small order really impressed me.
