We take pride in providing both exceptional service and great products. But don't just take our word for it, check out what some of our customers have had to say.
The defogger may was easy to install and is functioning just as it is supposed to work. All good.
WarmlyYours is very proactive with communication and their website is clear and well laid out. Very pleased with my purchase.
I was easily able to install the self-adhesive heating elements on the back of a very large mirror and wire them into the bathroom's ceiling fan circuit which I have put on a timer. I tested the glass temperature with an infrared thermometer and it heats up quickly (in my case, to around 28C from a starting temperature of around 20C) and is very effective at keeping the mirror completely fog free during long hot showers. It's a nice luxury to have.
I bought three custom-size heaters to avoid fogging in the bathroom mirrors, had them installed and they all work flawlessly. Customer service is fantastic and, despite challenging delivery instructions, WarmlyYours delivered.

Mirror Defogger Frequently Asked Questions
Can I use multiple defoggers on the same mirror?
Do radiant heating products have polarity?
How does a mirror defogger work?
What is the length of the cold lead for a mirror defogger?
Can I wire it to the lighting circuit?
If the defogger is smaller than the mirror, how far into the excess of mirror will this defog?
The defogging is concentrated in the area of the heating element, but may spread out as the mirror warms up over time. There are too many variable atmospheric conditions that make it impossible to quote a fixed distance of heat spread away from the element. That is why the defogger must be placed in the area of the mirror that requires defogging.

Installing a heating system behind your mirror is the most reliable way to avoid a foggy mirror. Typically, mirrors fog up because they are much cooler than the steam in a bathroom after a shower or bath. The cool surface of the mirror causes the moisture in the steam to condensate in the form of fog. A heated mirror will prevent this condensation by being as warm, or warmer, than the steam.

How thick is the box on the back of the heating mat? Does it prevent the mirror from lying flat or flush against the wall?
The electrical junction box should be installed inline with the Mirror Defogger’s lead wires and box. The box at the back of the defogger is meant to be located over the electrical box in the wall. This way it will be in the electrical box and not interfere with the defogger being flush with the mirror and the wall. The location where the wires leave must be entirely within the area of the new electrical junction box.
