Zoo Med ReptiTherm® Under Tank Heater (U.T.H.) 

Your heat mats are fantastic and they are not to hot and not too cold, keep up the good work!

it says we can't put hides directly on it! but if you have a gecko... you kinda have to. i'm so confused.

I suppose it's a liability issue on the part of Zoo Med, but it's ridiculous to say never put the hide over the heat mat. Everyone places their reptiles' warm hides right over the heat mat. You have to. That's the whole point of having a warm hide. What they should say in this video is that heat mats should never be used without attaching them to a good thermostat!

I've had my heating pad for less than 6 months and now it wont stay stuck to the side of the tank. Is there a tape or adhesive I can use?

im still questioning why you cant use a hide for leopard geckos, they need there belly heat so other heating devices wont work.

I have these on my Leopard gecko and Ball python and they love it! Thanks Zoo Med!🙂

Super helpful! I was hesitant to place it beneath her little hideaway! I'm glad I did not! 😊

They are great I use them in my cherry head outside enclosure in winter, i mounted them on the ceiling, perfectly makes thr temp inside at 72 while outside temp is 52-60

I purchased the 20 gal snake starter kit and one of these heating pads was included. I just plugged everything in and I let it sit for about 30 minutes, but the pad doesn’t seem to be heating up at all. I didn’t see any on/off switches so I’m assuming it turns on as soon as I plug it in. Am I missing something, or does it take longer to heat up?

Is there an on-off switch or do i just unplug and plug it in whenever i need? Also, do i keep it on all the time unless it gets too hot??

Would it be safe to put it under the tank on a dresser? I have a dresser and I think it's wood but since it comes with the things you lift the tank up will that help or is it just not worth the risk of overheating? Right now I am stuck with a basking light for my gecko (and I know those aren't good, this is temporary until I get the money for a heating pad which will be after this weekend) but I am wondering if lifting the tank up will prevent the mat from overheating too much.. I plan to get the smallest one once I get the money for it. Please answer, I have been really stressed out about what's good for my leopard gecko. The temperatures are fine in his tank right now about 90° for him on his warm side. He seems to be doing fine with his health behavior, and he's still active at night.. I just want to make sure he has belly heat.

I tried one. After about a week, it caused the bottom of the terrarium to crack all over, so the heater was the only thing holding the glass together. Switched to overhead ceramic heat after that.

More sizes need to be made available. At least up to 100 gallons.

I have my sand boa set up with a (thermostat regulated, cause that’s vital) heating mat with reptile carpet and aspen shavings. Problem is: she does her business under the substrate, and it’s difficult to clean up when it soaks into the carpet. Given the thermostat, wouldn’t it be fine to pull the carpet out and make sure the thermostat probe doesn’t get jostled out of position so the heat doesn’t climb? I think it’d save time cleaning if I could wipe/scrape her refuse off the glass and sterilize the area instead of dealing with something I can’t really clean that well.

can i use the heat pad on the back of the tank if i have spray insolation on the inside of the tank on the back?

Can the heat pad be easily removed? I clean my terrarium every weekend and I'm worried about it getting wet from the moisture.

How hot does an unregulated 8 watt mat get. Gonna have to do an experiment before attaching it to my aquarium for the humid hide. Gecko loves hanging out under the Arcadia overhead heat source.

I have them in 3 tanks and they are the best .warm side and cold side.gives the animals choices .

I ordered the ten to twenty gallon heat mat and was a bit shocked in how small it was it was VERY pricey but didn't even fit a twenty gallon heat mat it was smaller then my hide for my gecko very disappointed

Is it best to place on the sides or underneath for a crested gecko

My heater didn't even hear my terrarium? I plugged it in directly to the outlet with no thermostat (haven't had the chance to buy one yet) and it barely got warm...

But leopard geckos need a hide over heater right?

If I put this on the side of my tank for my aquatic turtle like where his basking spot is will it work still

Hello I purchased the Zoo Med 40 gallon under tank heater 2 days ago from Petsmart.. I followed the instructions and this video detailed upon installation.. I left it plugged in over night and when I woke up today the device wasn't producing any heat at all!!.. Leaving me to believe I purchased a defective product.. How do I go about this?

Is there a way to control the temperature of the pad on its own or do I need a separate device all together to change the temperature of the heating pad?

Do you know the temperature of the heating pad because I want to know if I can put it on the bottom on a wood shelf

Is it okay to run it 24/7 as a primary heat source? And will it be affected by aspen bedding?

I have the zoo med thermostat should I sandwich the probe between the heat mat and terrarium

I have used a few of these and they just don’t keep it warm enough

What temp should the mini 4w ones get to? I have two of them running. One of them is always substantially warmer than the other one. Using a laser thermometer, one of them reaches 107f at its hottest spot, and the other one 128f. Is there something wrong with one of them?

Yall have a plastic tank picture on the instructions but it says only use glass ... yes that's helpful

It doesn't stick to the side of the tank, it fall off in like an hour

how do you control the heat ? like what if it’s reading too high , what do you do ? just unplug it ?

So what if it's hot in the summer, do snakes still need the heating pad? Also can it work if the heating pad is on the wooden dressers?

Just to be extra extra sure, I can put the under tank heater underneath the tank with a stand that doesn't have a hole? By I mean it is a fully flat stand and it isn't specifically meant for a tank. I'm asking if it's fine to put the tank heater there as long as I put the rubber feet to help air circulation

How hot does it go? My leopard gecko can only go up to 93 degrees Fahrenheit and the heat mat goes higher. Please help!

how high of a temp does this mat go up to?

R they reusable?

How large is the 50-60 gallon UTH?

can you adjust the heat or do you have to buy something to go with it also is this recommended for leopard geckos

30-40gal is not nearing my needs for a 40 gallon enclosure for my ball python

How do you know if it's working

Do you need to put the rubber feet on an enclosure if you are putting the enclosure on a metal wired surface?

Can I like put it next to plastic tubs so it warms the reptile, but is not on the plastic?

breakers use paper towels on their tank with the under tank heater they say it's fine but you say to avoid them ?????? who's right ???

I plan on using eco earth substrate for my leopard gecko, should i still put a carpet underneath the substrate?

So I'm getting a gecko soon and everything I've read or watched said to place the hides over the heat pad and I'm not really sure what to do now can someone help?

hey, I have a banded knob tail gecko and I’m worried about using a heat mat. I have an exoterra terrarium, and the heat mat is needed as my geckos are nocturnal, but my terrarium is placed on a wooden table. Would it be alright to keep the terrarium on the wooden table, or would it burn? thanks

for an adult leopard gecko with reptile carpet as the substrate is it better to have it place on the bottom for belly heat or the side to provide warmth throughout the tank? I personally would like to have it on the side but would that be bad or is it neutral, if either way works well enough to keep the tank warm enough I'd choose the side unless not recommend.

What is the point of removing the air bubbles?

Zoo med I have a leo gecko and I put its hot hide on top of the heat mat is that bad

I have a zoo med 10 gallon tank that came in a start-up kit, and I’m guessing since it’s made with space underneath I can use you guys heating pads as well? The tank doesn’t seem like glass and I don’t know what material it is so I wasn’t sure if it was safe

So i have sand at the bottom of the tank and on top of the sand I have put paper towels (since I don’t want it ingesting the sand) is it safe to use a heating mat under it? Or would it still be dangerous?

I have a sterilite plastic tub, best option for my set up to retain proper heat and temperature for my Ball. Would like to use ZooMed pad for it. Why do you say that it's not recommended for plastic tubs like Sterilite? I'm pretty sure your pad temperature will not be hot enough to melt plastic. Is there another concern that I'm not thinking of? P.S. I'm also using a thermostat set to 97*F in hot spot.

HELP PLEASE!! Building a WOOD Enclosure for my Leopard Geckos. Size: 24”Depth, 48”Width & 17.25”Height I see people put the Heat Mat inside on a corner and cover it with substrate (I’ll be using Eco Earth). Now is this a good brand to buy? Will it get hot enough? If so, what size should I get? If not, what other brands are better? I’ll be buying the Jump Start Controller Thermostat. Thank you!!!

Ok so can someone explain to me why I would put it on the side vs the bottom. I just want to understand so I make the right decision on where to put mine.

How do we wash the tank after we put the heat pad on?

What’s the best way to clean so it sticks to glass again? I had to peel it off to clean tank and now it won’t stick on again

So it's ok to put on the side of the tank? I didn't get that. I would appreciate an answer, as I am considering buying this for my hermit crabs.

Just got one today, I have the heat mat, and and a heat lamp but the temperature is only around 78°. this is for a leopard gecko. any tips on how to get it warmer?

Is it better to mount on the bottom or side when using for hermit crabs? I also have mine setup on a tv stand. No feet were included 😣 but I could prop un the corners using felt chair feet pads.

All the videos I've watched says to put the hide above the heating pad for a corn snake?

so, i am gonna get leo geckos, and i know I will get a UTH. I heard about your Repti Shelter, can I just put that over the heater?, I mean, the tank edge and the tile substrate will seperate the shelter from the heater, so is it still safe? And because I am a begginner, all I have to do to make a moist hide is put some damp eco earth in right?

I have a question? Can I put a heat mat on a regular plastic tub for my ball python! I also might put heat tape on instead!

I have a leopard gecko and was pretty sure I was going to place it under the tank but now that you mention it I was wondering, would I be able to put it on the side then put a basking rock by it for extra warmth?

I have just got one of these for my frog and it doesn't seem to heat the water in his tank at all and the guy at the store recommended this, what should I do?

so do I unplug the heater when I go to bed or do I ever unplug the heater?

And it says you should have a hide by the warm side so if it cant go directly where the heat mat is then where do i out it

Is the forest floor bedding considered light weight substrate or heavy substrate? Also we have the Exo Terra tank which has “feet” so to speak already built in with the frame, plus I was going to add the included rubber “feet” so do I still need to use an open top stand?
