10 reviews for 70 sqft Mat Kit, 120V Electric Radiant Floor Heat Heating System w/Aube Programmable Floor Sensing Thermostat

  1. Bernie

    Good performance for the MoneyWe had a contractor install this and he did so with little difficulty. The only caveat is the difficulty of switching the thermostat from Celsius to Fahrenheit. We left it on Celsius as we were worried we would break something trying to switch it. It should be easier to do. Other than that you have the flexibility to adjust settings by day. Some may find that inconvenient than just the push of a button for all days. It’s pretty straight forward to program. Overall we are pleased with the product and hope that we can post a follow up review in 5 years to say that it continues to operate effectively. It’s only been in operation for 2 months now. But we LOVE the heated floor!

    COVERAGE NUMBERS ARE MISLEADING. DO NOT PURCHASE THIS W/O CONSULTING COMPANY & SENDING THEM YOUR FLOOR PLAN.3 stars is my NEUTRAL rating. I didn’t finish installation, was disappointed in original product. Went through return/exchange process. 5-star customer service in the beginning. Then less-than-5-star customer service. Ended in refund because they made it so complicated that I was afraid of the product and was wasting WEEKS sitting around waiting for a way to fix the problem (ONE BATHROOM HOUSE FOR FAMILY OF 5 FOR WEEKS IN A ROW? NO THANKS!). Which made me really sad, because others had such success and were very happy, and this was a great value, and because I really wanted my bathroom floor heated. But not enough to continue through this nonsense.I measured my room many many times and found that the original sq ft I wanted to heat was 34.5 sq ft. So I bought this as a 30 sq ft mat so that I wouldn’t have extra length (since you can’t cut the wires). It didn’t fit. Their 30-square-foot-mat took up more than 34.5 square feet. It didn’t even come close. I had like 4 FEET left over at the end.So when they contacted me for a review, I told them what happened and they offered 5-star customer service in replacing it with a smaller size, offering help determining what size I needed, and even offering a refund if that’s what I chose (even after my Amazon return window had expired)!!! I was super pleased.Then the agent I was working with stopped replying to my emails, and over a week later, a different person called to confirm that I wanted a 20-sf mat…. She called back more than 4 times in less than an hour, asking questions and confirming things I had emailed them about a week beforehand. Then, she made me go and measure my space for a 200th time so they knew they were sending the right size (because I had no way to send them my floor plan)…. She even made me feel like I didn’t know how to read a tape measure or measure the room. Great self-esteem boost. It’s not that hard — my space is a square that is exactly 6-foot by almost 5-foot…. and that’s after staying away from walls and not being under the toilet or tub or vanity or shower. I’m not a total idiot. Then. She proceeded to try and explain to me why the 20-square-foot mat MIGHT NOT FIT into my 28-square-foot space either (I made my heated space smaller when I knew I had to get a smaller mat) and that she might want to send me the 15-sf mat instead so that I didn’t have the same problem the 2nd time……(15-square-foot mat to heat a space of 34.5 square feet that I originally wanted heated…. or even 15-square-foot mat to heat a 28 square foot space after I made changes….. tell me how that makes any sense! Product description FAIL.)At that point, I asked for a refund. If they advertise it’s a 30-sf mat, it should fit in a 35-sf spot with space left over. If they advertise it’s 20-sf, it should fit in a 28-sf spot with space left over. If it’s really that complicated to determine what size of mat I *actually* need (because you can’t rely on the product title for an accurate idea of coverage!!), I shudder to think of how difficult it would be to actually install the product to fit the way I want and warm the places I wanted warm.

    A Great Way to Heat Floors.If you ever wanted floor heat this is the way to go. It was easy to install. I watched various videos to see the pitfalls and tips. The biggest fear and caution is to not cut the wire. I was appropriately paranoid about this. I ran several continuity checks. Then I had to worry that the tile guys laying thinset and tile over it didn’t cut it. They were very careful. They even devised a plastic trowel to work the thinset. When they were done I ran one more continuity check and it was still OK. With that I hooked up the power and the thermostat and voila it worked. I got exactly what we wanted in our renovated bathroom, heated floors.

    Defective thermostat that I cannot return since mat has been installed – update: heating technologies rectified the issue!Ordered the heat mat and got it installed in a new renovation; however, once power was hooked up to the unit, I discovered that the thermostat itself is defective. Given the seller’s return policy, I can no longer return/exchange the item, so I’m not at all satisfied. I’m now going to have to find a 3rd party to buy a working thermostat from.Update 8/29: I was able to get in touch with Heating Technologies and they promptly sent me a replacement thermostat. I was very impressed with their customer service, and I’m now happy with the product. Thanks again to Heattech for their quick, effective handling of my issue!

    Installed great. High QualityI ordered this a few months ago. I just got around to installing it. I have been very much impressed by the quality of the product and the thermostat. The kit comes with everything you need for installation, except an electrical circuit. I’m impressed by the quality of the mat and the thermostat. This has definitely been a good purchase.

    quit working after 2 yearsThis went into a new bathroom addition on my house, with a dedicated 120v circuit. I installed this myself using a screamer tool, plus checks with the ohm meter. My tile guy installed the floor over the mat, and said he was extra careful.Everything worked great for two years. I loved having warm toes in the morning. After being off at the breaker box all summer, i flipped back on this winter and the floor would never get warm, no matter how I set the thermostat. I finally got around to pulling out an testing the theromstat, and it seems to be working fine.I busted out the ohm meter on the heating wire and it shows no resistance. I could figure out how the wire would have gotten severed after two years of being between hardie board and ceramic tile. If i had never installed this I wouldn’t know what i am missing, but I am so disappointed!
