Reptile keepers love Ultratherms as a safe (low wattage), durable heat source that provides a very uniform heat output. Plus, they're so easy to use—simply tape either side of the UTH to the enclosure and plug it in. It's that simple and will outlast any other heat pad on the market.
Made in Scotland, these under tank heaters are specifically designed for the vivarium keeper. The 6"x35" UTH uses only 23 watts, and comes with a 6-foot cord and plug.
The same technology as the Flexwatt Heat Tape is used, but it has been manufactured into a pad with an additional polyurethane coating to ensure moisture resistance and durability.
These low-wattage pads are regulated to stay between 65F and 95F (depending on exterior temperature). We recommend using the UTH in combination with a proportional thermostat or a dimmer to achieve precise temperatures. In fact, Ultratherm under tank heaters should always be used with a suitable vivarium thermostat. For species which are particularly temperature sensitive, or in environments which could prone to overheating, it is important that thermostats are used to provide full temperature control.
Low wattage, long life, and excellent cost make these under tank heaters great for using with snakes, lizards, inverts, hermit crabs and small animals. This is a UL listed component.
Information specific to Crabitats: 80F-85F is the ideal temperature range in hermit crab enclosures. This is best achieved with Ultratherm under tank heaters (UTHs) placed on the back of the tank to provide a heat gradient (a warm zone and a cool zone).
For sizing, choose the size that has a length closest to your total tank length, and a height closest to half your tank height. The size recommendations (pictured) assume the minimum requirement of substrate depth (though half of the tank height is the ideal depth of substrate).
For placement, the UTH should cover most of the back wall, sitting right above the substrate line if possible. A couple of inches of overlap with the substrate is okay.

This UTH pad is by far the best I've ever used. I love that it doesn't just stick to the tank. It has been keeping my whole tank at the set 81 degrees and my hermit crabs are a lot more comfortable, happy and active. It came quickly and was well packaged. It is made so well, it's not like the cheaply made expensive ones that dont work well and fall apart. Reasonably priced for the amazing product you get. I will never get another UTH from anywhere else!
Perfect size for my tank. Excellent customer service. They helped guide me on best way to install for maximum effectiveness. Now my crabitat stays in the correct ambient heat range.
These heat mats are amazing! I was having a really hard time keeping the heat and humidity where they needed to be for my hermit crabs and this mat was a game changer! I have it insulated with some reflectix in this picture because I live in MT and it can get really cold here and the mat is fabulous! :) The hermits love it and it was worth every penny, really well made and easy to tape up on the outside!
Absolutely Wonderful product! Keeps our Hermit crabs warm and happy. I love that it can be insulated and reused easily. We have it hooked to a thermostat and easily maintain 81degrees. We will definitely recommend and purchase again when needed.
Used it on my topper for my 40 gallon breeder hermit crab tank! It’s perfect & heats up very quickly! The service team was also very helpful! Even called me to make sure I wanted to keep my order because I was confused on sizing!
I actually found out through a review at PetSmart. I followed the referral to this Matt and I’m absolutely in love. I’ve never had a better heating system for my crabs.
Easy to order, they had the perfect size. It’s very simple to install and does its job well. I have a smaller one and knew I wasn’t going to order anywhere else.
Perfect for my 29 gallon tank. Fits the back perfectly and heats well! This is my second purchase from them and my previous heat mat lasted over 5 years, still works but I needed a larger one and made this purchase!! Thank you!
Fits great along the back of my 36in tank :) insulated with tinfoil and cardboard to direct the heat into the tank and its working great! Love that I can take it off and move it if needed
The UTH fit my tank perfectly! It’s so easy to use and contacting Bean Farm with a question wad so easy and I got a response back very quickly!! I couldn’t be happier!
I installed the 11x35 heating pad with some reflectix insulation behind it and on one side of a 40 gallon breeder tank for my hermit crabs. It heats FAST and super consistently (fluctuating less than 2 degrees over the course of a day). I am honestly beyond impressed with the improvement from a cheap stick on heater to this. Especially at the price point. 100% will recommend this brand anytime.
I have ordered 3 times from this company and have not be disappointed. Absolutely love our 6x11 heat pad, 11x11 I believe and the thermostat. Recommend this company all the time.
The picture is with smart shield over the top. But it is great. It’s keeping a consistent temp even though we live in a colder area. Bean farm was amazing and even answered my questions over email. I highly recommend them if you are in need of a heating pad and or a thermostat.
Excellent heating option , especially with animals that require higher humidity. I keep mostly Blood pythons , and with the heat mats , the proper substrate mix releases sustained moisture in the enclosures , while keeping the necessary temperature. Highly recommend.
You have a great product, I’ve been buying from bean farms for some time. And shipping was also very fast thanks again for a great service.

It was a little bigger than I needed but works perfectly for my hermit crab tank and gives them the heat they need. I have a thick substrate so I have it on the back and it goes over to the side and they have been busy ever since! Packing tape was used to put it up and it was easy. Thanks to crab central station for the recommendation!
Ulta thin and ultra warm, this UTH heats my 60 gallon hermit crab terrarium. Easy to use, just tape in place. Super fast shipping, too. Highly recommend!
Love my new beanfarm heat mat. It spans the entire length of my 55g crabitat and keeps them nice and cozy in their prefered tropical climate. It was easy to install onto the back of the tank
Heat mat is easy to use and works…however the one I purchased is too small for the tank size I have. Doesn’t keep hermit crabs warm enough so I will need a bigger size.
This heat mat is the PERFECT size for my 75 gallon tank. I used Hvac tape to attach it to the back of my hermies tank. :) so far the temperature has stayed a constant 77 degrees but I think I may insulate it to get it up to the desired 80 degrees. Shipping was fast and arrived packaged perfectly!
