Underlayments for Floor Heating


Description

Depending on what products you are using to install your heated flooring system, you’ll choose between two cork underlayment options. Real cork ideal for concrete slabs, however our synthetic product is the preferred underlayment for radiant tile and stone floor heating. Underlayment options increase energy efficiency with heated floors and they are also heat and cold resistant. Perhaps most importantly, they will not rot, absorb moisture, or support mold or mildew. This extends the life of your floors and provides a cost effective method for installing the best radiant heating floor system available. If you’ve been considering installing a heated floor in your home, you should consider the benefits of using CeraZorb Synthetic Cork Underlayment or standard Cork Underlayment sheets. With a limited warranty included in the purchase, you can trust that WarmlyYours products will stand the test of time in your home. To find out more about which underlayment option you should choose for your heated floor, contact WarmlyYours today.

What type of flooring can I install along with an electric floor heating system?

WarmlyYours’ TempZone™ product is most commonly installed under tile, stone, and marble flooring, but can also be installed under many other popular floor covering options such as hardwood, vinyl and linoleum. We also have our Environ system, which is an electric floor heating product as well and is specially designed for installation under carpet (in the U.S. only), laminate and floating wood. WarmlyYours can accommodate any flooring type with either of the electric radiant floor heating products that we offer. If your flooring type isn't listed here, just give us a call at (800) 875-5285 and we will be happy to discuss it with you.

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.

Should I add insulation before installing electric floor heating and how will that affect the system's performance?

When installing electric floor heating over a concrete slab, an insulating underlayment like CeraZorb is highly recommended to ensure efficient operation, faster heating times and warmer floor temperatures.

great customer service

Terry D., Lake Zurich, IL on 10/29/2022

Shopped around at big hardware stores but WarmlyYours offered a greater selection and terrific customer service. They were very responsive to questions, and helped me with an exchange when my original purchase was slightly oversized for our sunroom. They were also helpful with my contractor handling questions he had about the installation. The radiant heat in our sunroom floor has made the space so enjoyable during this cool fall season.

Easy

I ordered WarmlyYours for a client of ours and she just moved into the home we renovated for her. She loves the fact that she stay toasty warm in the bathroom.

Amazing service

Brad S., Des Peres, MO on 07/11/2022

I was going to use a competitor's product, but every place that 'carried' it I also had to order it. Since the tile guy was coming over on a specific date I needed to make sure everything was in place, & based on experience I couldn't trust Lowe's or HD's site when it said it would come in by a Wednesday of the week needed. I called WarmlyYours, they confirmed that they had all the items in inventory & could ship the same day. I texted the bathroom plans and later that day they got back w/ the design and a quote. I ordered it that Friday afternoon, and was shocked that it showed up at my door the next day-Saturday. Everything went as stated. Very nice when facing delays w/ so many of the other items in our project.

Great customer service

I’ve been trying to find an easy way to warm up my son’s bedroom above garage, when I came across WarmlyYours. The radiant heating system was designed by WarmlyYours and installed underneath our new carpet. The whole process was great. We couldn’t be happier. It looks and works great. Thank you.
