How do I know if I am installing my electric floor heating system properly?

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.

Can I use electric floor heating as a primary heat source?

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.

How can I make my basement warmer?

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.

simple and straightforward

Jennifer W., Laguna Beach, CA on 06/25/2024

I replaced my programmable thermostat with with unit that is merely on/off. Where I live, the radiant floor heater is not used that often. It performs as expected.

A Company That Makes Customer Service a Priority

Dale M., Colorado Springs, CO on 05/20/2024

Everything about my transaction with WarmlyYours was a unique surprise. No other company I have EVER dealt with recognizes and appreciates the value of good customer service. It is difficult to exceed my expectations when it comes to a purchase transaction; hey did it with excellence.

Great Product…Great Customer Support…

Terry H., Edmonton, AB on 05/10/2024

My Flexzone heat mat was easy to install and awesome customer support.

Great experience, great product

Cheryl S., Gloucester, ON on 04/05/2024

I wanted underfloor heating in my kitchen for a long time. However, most systems are too thick and would create issues with adjoining flooring. When I discovered the WarmlyYours system my reservations were resolved. The mat is only 1/8th of an inch thick! Once ordered, I received the product within 24 hours. It installed easily and is working beautifully. My longtime wish has come true.
