Customer Questions & Answers
TempZone Cable Kits with Fixing Strips and nJoy WiFi Thermostat has 1 Questions and Answers.
Is installing reflective insulation effective for making an electric radiant floor heating or snow-melting system more efficient?
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.

Jennifer was awesome
Mike C., Basalt, CO on 06/17/2025
Great to deal with! Made everything super easy and transparent and easy to understand.
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…
Anonymous, Arlington, VA on 05/21/2025
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!
