Customer Questions & Answers

TempZone Cable Kits with Fixing Strips and nJoy WiFi Thermostat has 1 Questions and Answers.

Don't see the answer you're looking for? Post your question

Reflective insulation is not effective with conductive heating, which is how embedded floor heating and snow-melting systems transfer heat. To be effective, the reflective insulation surface needs to face an air space (air gap), which allows the reflected heat to be redirected.

An effective solution considers the insulating material's R-Value. This is the rating of a material's insulating properties. The "R" stands for "resistance" and refers to the material's resistance to heat flow, or temperature conduction.

Easy installation. Set-up a little more challenging.

Carol L., O'fallon, IL on 06/09/2025

Installation was easy. We did have some initial problems with pairing the thermostat with my iPhone, however. After talking with tech support, I was advised to attempt the pairing process multiple times. Eventually the pairing was successful. Although a bit frustrating, we were finally able to program the thermostat successfully and it is working fine.

Response from WarmlyYours:

Thank you for your review. The issue that you are referring to stemmed from a security setup quirk present on IOS devices. Now that we have learned how to configure the bluetooth settings in iPhones, this situation has been resolved and the setup can be done very quickly and easily. - Scott, Technical Support Manager.

Works well - thanks!

Works well - thanks!

Excellent Customer Service

Laura H., Santa Monica, CA on 05/22/2025

I called WarmlyYours with an issue regarding my heated floor. They quickly determined my 15-year-old thermostat was no longer working, sent one to me within a week and gave me the contact information of someone who could install it. My floor is up and running!

A responsive team, easy to work with…

I selected WarmlyYours from a host of competitors due to the woman-owned business and small business status. They offered better customer service throughout the installation process, from mechanicals, to setting the mesh under marble tiles. It went very smoothly and the heating system works.

Will remain a loyal customer

Kevin B., Norton Shores, MI on 05/12/2025

I bought the updated thermostat to replace the old one that was no longer working in my customer's home. Their videos helped me diagnose the problem. The install was super straight forward. Their customer service is legit. I don't have heated floors in my home, but am putting them in my bathroom later this year. I will for sure use the WarmlyYours system, no question.

Great

Fixing strips are on the cheap side but were free and did the job. Heated floors are a wonderful addition to the house.

Toasty Feet :-)

Kathie S., Scottsdale, AZ on 04/30/2025

We have just used our new shower for the first time and we are thrilled to have toasty feet when we step into this beautiful enclosure. This is the 3rd time we have installed your product and although I hope to never move again - I will be recommending your product to all my friends and family.

Love the warmth

Anonymous, Knoxville, TN on 04/10/2025

Was unsure but it was a small area and decided to proceed. No regrets what so ever. Love the warmth radiating from the tile floors! The installation was somewhat of a challenge for my inexperienced husband. But installed now….no looking back!

Great product. Great service!

We’ve purchased from WarmlyYours twice now and have been thrilled both times! The product is easy and intuitive to install and we love having warm floors. What really sets WarmlyYours apart is their outstanding customer service. They will help you select the right product and are extremely friendly and knowledgeable. 5 stars!
