Zoo Med ReptiTherm Under Tank Heater, Medium

The description says this is an 8x12 heater for a 30-40 gallon aquarium, but I received a smaller heater for a 10-20 gallon aquarium. I reported the item was wrong and asked for a replacement, but got the same thing again. Zoo Med sells the 30-40 gallon size as a medium heater. This seller is selling a smaller heater but calling it medium.

This is a highly recommended under tank heater and so far is hasnt disappointed me. It comes with an adhesive side but I recommend using the foil tape along the edges to attach it to the underside of a tank/tub. It will ensure that it does not come loose and fall off, thus reducing the risk of the temperature dropping in your enclosure. I use mine with a thermostat and I apply the probe directly to the mat (with another piece of foil tape) and while it doesnt recommend using with a plastic tub, I have mine attached (as do many other experienced snake keepers and breeders) and do not have an issue. You cant control the heat without a thermostat (you can get one for fairly cheap) as you just plug it in and its on. There is no on off switch or dial for adjustments. The price is reasonable and Id definitely recommend this brand to anyone I know in need of an UTH.

Works just fine, ALWAYS put your heat mats or any heating element on a thermostat for your reptiles! The adhesion isn’t the best, simply use foil tape and tape the side of the mat to your enclosure.

Perfect for attaching to the back of a 29 gallon for our giant Madagascar day geckos. I found a bamboo drawer organizer to put against the glass so they dont burn their bellies. They mostly hang out right over where the corners of the mat are. I like that its large enough they can go to the nice toasty middle or a cooler corner area.

Stopped working after 6 months of use. But? Im gonna buy another.....nothing else quite works like these. Ive been using them for years and have never had issue with them getting hot enough to burn my lizard or exploding, which is a thing heat pads do sometimes. Chalking this up to some quality control issues, not serious enough to have to redo my heat setup around a new pad that might be less safe. For what its worth Ive had plenty of zoomed pads still working three+ years down the line, tho I try to retire them a little sooner than that for safety reasons.

I like everything about this heating pad except for the adhesion. This is replacing one that had the same issue and it’s replacement stayed adhered, but eventually just quit working. At the time of adhering the original one, I only had the tank on the tiny spacers that come with the product. The company did replace it and my husband welded a stand that allows for much more air flow. The replacement worked for about a year then quit. I ordered this one and after about 6 weeks it has fallen right off the tank. I do have one other tank with one on it and it is still adhered. When it works it is great and I’m completely satisfied, but 2 of 4 have come loose with what I thought was proper ventilation and 1 of 4 just stopped working.

Its doesnt heat up all they way , its just getting like warm. Iv plugged it straight into the wall and doesnt heat up and into a thermastat and doesnt heat up just like warm.

Dead after 9 months!!! Thought I still had 3 months before I would need to buy again. Now I need to buy an emergency heat pad for my reptile!

Keeps my python’s warm hide between 88-91F. Great for my 40 gallon breeder. It also has a battery backup, so if the power flickers, it will remember your temperature setting. A MUST have for ball python owners.

It was just what my Geckos needed
