Top 8 Best Under Tank Heaters to Buy Online 2020

Reptiles and other cold-blooded animals can be unique and interesting pets to keep, but they also require some special considerations that a dog or guinea pig wouldn’t. The most important consideration is probably temperature. Unlike warm-blooded animals, reptiles and amphibians need outside heat sources.

One of the safest and least obstructive types of heaters you can get for your enclosure is an under tank heater, a pad that emanates heat from beneath a portion of the tank. In this guide, we’ll go over the factors you should consider when choosing which under tank heater is best for your pet. At the end, we’ve also got a list of our eight favorites to help you get started.

How to Choose an Under Tank Heater – Buying Guide

Every animal has different needs, so before you consider getting an under tank heater, make sure that this kind of heating source would work for your pet. Under tank heaters are great for animals that don’t require UV light and don’t have basking tendencies. Alternatively, they can make for great secondary heat sources.

Choose a Size Based on Wattage and Tank Size

Choose a Size Based on Wattage and Tank Size
While reptiles do need a heat source, your under tank heater shouldn’t cover the entire bottom of the tank. Instead, it should only be on one side, creating a temperature gradient within the tank and allowing your animal to regulate its own temperature by deciding how close or far from the heat to be.
It’s also more than just surface area as the heater has to also be strong enough to heat the air within the tank.
An easy way to figure out which sized mat to buy is by looking at the wattage. For every 20 gallons a tank can hold, you need about 8 watts of power. So for a tank between 30-40 gallons, look for about 16 watts. For 50-60, look for around 24 watts.

Getting the Right Temperature is Crucial

It isn’t as easy as saying that all cold-blooded animals need external heat. You also need to be able to regulate that heat, so it’s important that your heater matches the temperature needs of your pet.

Look for a Built-in Thermostat for Easy Temperature Control

Look for a Built-in Thermostat for Easy Temperature Control
Having a thermostat will allow you to control the temperature of your heater as well as the temperature inside the tank, which is extremely important for reptiles. However, most under tank heaters do not come with a thermostat, which means that you might have to buy one separately. For convenience though, it makes sense to look for one that comes built-in.

A 100º Heater Will Work for Almost Any Animal

A 100º Heater Will Work for Almost Any Animal
If your heater doesn’t come with temperature control, look for one that puts out 100-degree heat. While different animals have different heat requirements, it’s very likely that you won’t need more than 100 degrees. However, make sure you always double check with a specialist to ensure that your heat pad will provide ideal temperature levels for your pet.
Of course, it’s important to also have a thermostat so that you don’t overheat your tank, but 100 degrees is a good temperature when you need to bring your tank back up to heat quickly without damaging your enclosure.

Sticky or Not Depends on Placement and Animal Type

Sticky or Not Depends on Placement and Animal Type
Some under tank heaters are adhesive while others are not. The type that you want will depend on whether you plan on moving it around as well as what kind of animal you have.
Adhesive heaters are great if you know where you want it to be and have no intention of changing layouts. They’re also good for burrowing animals. Since having a heater under the tank may be too hot for animals that burrow, an adhesive heater allows you to stick it to the side of the tank instead, which gives animals more control over their temperature.
Non-adhesive heaters, on the other hand, are more easily moved and can offer cooler temperatures and more airflow than sticky heaters. These are better for animals that require lower temperatures like frogs and geckos. Of course, you can always use an adhesive pad without the adhesive, too.

Are Under Tank Heaters Safe?

Are Under Tank Heaters Safe?
Heat-generating appliances are always a little concerning, even if they only operate at low temperatures. But you should know that under tank heaters are actually one of the safest types of heaters for animal enclosures.
First of all, they only reach relatively low temperatures, which means that you don’t have to worry about them doing much damage. They’re also waterproof, and when you have a heater around areas that could potentially get wet (like animal enclosures!) that’s incredibly important.
Plus, because they don’t give off any light, you can have them running 24/7 and use them as your only heating source. This means that instead of requiring multiple heating sources, you may be able to have just this one. But again, always remember to have a thermostat connected to keep conditions ideal for your animal and always read the directions!

Summary

So there you have it–a quick guide to picking out the best under tank heater for your pet. With a good heating pad, you’ll find that your pet will be happy and healthy and enjoy efficient digestion.
