Is Your Gun Safe Dehumidifer Hot? This is What You NEED to KNOW!

For many, if not all people, a dehumidifier is a must for a gun safe. There are desiccant, rod style, and many other types of dehumidifiers that are purpose-built for gun safes. However, the dehumidifier rod is the most popular way to keep a gun safe from condensation. However, many people find that their dehumidifier rod is hot.

Dehumidifier rods, in particular, are designed to heat up. This is so that it can slightly raise the temperature of the safe’s interior so that condensation doesn’t form and settle onto firearms, resulting in rust, corrosion, or even mold.

Dehumidifier rods heat up to around 150 degrees, which, according to Safe and Lock Store, is the perfect temperature to allow for airflow in an otherwise almost airtight safe.

When you get airflow and some heat, condensation can’t settle down the bottom of the safe. Instead, it continues to stay in the air. If a safe sit too long without airflow, you can find pitting on your firearms, damp surfaces within the safe, and even mold all over the safe carpeting.

Best practices are always having some dehumidifier in your safe at any time, and their added heat is a big part of their benefit.

What dehumidifiers don’t heat up?

Of course, only some people want something that heats up within their safe, and if this is an issue you have with your current unit or you are shopping for an alternative, there are some great options. These options include desiccant and cordless units.

Why do you want a dehumidifier that heats up?

Now, you may ask yourself why you even want one that heats up. This is mainly because the rods are incredibly efficient at what they do. You can leave them in your safe and not think about them again! The other options must be recharged or replaced regularly, meaning you must keep track of that.

Where is the best place to put a dehumidifier in a gun safe?

Because dehumidifier rods get hot, I highly recommend putting your dehumidifier in its own place. Ensure firearms, fabric, or anything else don’t cover it. It needs to live in its own space, work efficiently, and stay safe.


A dehumidifier is essential for your safe! Dehumidifier rods, in particular, do heat up, and nothing is wrong with your unit if it is warm or even hot to the touch. It may be warm,
