Frequently Asked Questions (FAQs)

1. Are terrarium heating pads safe?

Terrarium heating pads are considered safe when used correctly. It is important to set up the pad properly to create a safe and warm space for your reptile. Following the recommended guidelines and instructions will ensure the safety of your terrarium and your pet.

2. How hot do terrarium heat mats get?

Terrarium heat mats, also known as under tank heaters, typically reach a surface temperature of about 90-95 degrees Fahrenheit in an average room temperature. These heat mats use low wattage density heat elements, which means they don't get very hot and consume very little electricity.

3. What is the cheapest way to heat a terrarium?

The cheapest way to heat a terrarium is to utilize natural sunlight. While additional heat and light sources may be needed, natural sunlight can provide a cost-effective heating solution for reptile tanks.

4. Do heat mats go inside or outside terrariums?

Traditionally, heat mats have been placed on the floor of the terrarium under the substrate. However, this can be dangerous and increase the risk of burning the animal. A safer method is to mount the heat mat vertically on the side of the terrarium.

5. Do reptile heating pads go in or under the tank?

Reptile heating pads, also known as undertank heating pads (UTH), are efficient and reliable tools for providing heat to reptile and amphibian enclosures. Some varieties are self-adhesive and bond directly to the glass terrarium bottom, conducting heat to the enclosure floor and substrate.

6. Should heat mats go on the side or bottom?

Heat mats are traditionally mounted on the underside or bottom of the terrarium to provide heat from below. However, when there are several inches of soil or other substrates on top of the heat mat, this may not be an effective way to create a warm basking surface.

7. Do you leave heat mats on all night?

When using a heating mat for seed propagation, it is recommended to leave it on for 24 hours a day. This consistent heating is necessary to support the propagation process. However, for terrariums, it is important to follow the specific guidelines for your reptile species and consult with an expert if needed.

8. What is the most efficient way to heat a terrarium?

Heat pads, heat tape, and heat cables are all efficient ways to heat a terrarium from below. However, it is essential to use thermostats to regulate and maintain appropriate temperatures. Providing an air space around the under-tank heating devices is also important for efficient heating.

9. How do I keep my terrarium warm without electricity?

If you need to keep your terrarium warm without electricity, there are alternative methods you can use. These include heating up rocks on a gas grill, wrapping them in towels, and placing them in the enclosure. Another option is using hot water bottles filled with warm (not boiling) water. Additionally, sharing your own body heat by placing the reptile next to your body can help keep them warm.
