Should I use a heat lamp, hot rock or heat pad?

Snakes, being cold blooded, need to be able to thermoregulate their bodies. They do this by seeking out the appropriate temperature for the task at hand. They need access to warmer temperatures in order to be able to properly accomplish many tasks in life, including digestion. Now, each of the heating methods listed can provide a heat source, but which one is best? For most commonly kept snakes, I would recommend a heat pad, or under tank heater (a UTH) hands down and I'll tell you why.

Snakes are secretive animals. They will spend a great deal of their lives in hiding. After a snake has just eaten a good sized meal, it will feel especially vulnerable and will hide out for several days while it digests its meal. It will need heat to properly digest this meal. So, we know it wants to hide while it digests its meal and we know it needs heat to digest it properly. That is why a heat pad or UTH is the favored heating device by most keepers.

Hot Rocks

Hot rocks will provide a heat source but they have many bad points that far out weight their heating capabilities.

  • They do not heat up evenly and can have some spots that are dangerously hot.
  • They do not come equipped with a temperature control device and can reach temperatures far too hot for snakes.
  • They do not allow the snake to hide while utilizing the heat source.

In my opinion, those points make them the worst choice of the three heating methods. That's not even including the numerous pictures I've seen and stories I've heard of snakes being burnt and even killed by hot rocks. If you have a hot rock, cut off the cord, use it as a cage decoration and go buy a heat pad.

Heat Lamps

Heat lamps do basically what the sun does. They heat the air and provide an ambient heat gradient. They are great for some species of snakes but not ideal for others. If a heat lamp is what you've chosen as a heat source for your snake, you should be aware of a few things.

  • A heat lamp, if the snake has the ability to reach it, can also cause potentially fatal burns to you snake.
  • Heat lamps will have to run at a higher temperature in order to provide the proper temperature in the snake's hiding spot.
  • Heat lamps pose the highest risk of fire of the three heating methods.
  • Heat lamps can make it difficult to maintain a suitable humidity level in your snake's enclosure.
Heat lamps do a better job than a hot rock and are the ideal heating method for some arboreal snakes but given their possible risks, I would avoid them if possible. If used, they need to be out of the snake's reach and in a spot where they cannot be knocked over.

Heat Pads

That brings us to heat pads. Heat pads, when equipped with a controlling device, are the safest and most efficient method of heating. Be it a store bought commercial heat pad, a human heat pad, heat tape or radiant heat panels, an under tank heater has all of the things your snakes needs without many of the risks.

  • Heat pads provide heat where the snake will use it most; in its hiding spot.
  • Heat pads are safe for the snake to come in contact with if they are controlled by a dimmer or other means.
  • Heat pads can be set to run at the exact basking temperature your snake needs.
  • Heat pads provide an even temperature and allow for a proper heat gradient.
  • Heat pads, when used properly, pose little risk to your animal.
Heat pads come in many sizes and price ranges and can be found at most commercial pet stores or ordered online from a variety of suppliers. They are, by far, the heat source I would recommend for 98% of commonly kept snakes.


DISCLAIMER: All heating devices should be used properly to minimize the risk of fire. Always read the instructions and measure the temperature before allowing any reptile to come into contact with the heat source.
