The 6 Best Boat Dehumidifiers to Go From Damp to Dry
Reasons to Use a Boat Dehumidifier
- Remove humidity from the air for a comfortable living space
- Improve air quality
- Prevent mold, mildew and bacteria
- Prevent the growth of dust mites
- Dry condensation on windows
- Protect the wood and metal in your boat
Types of Boat DehumidifiersThe type of boat dehumidifier you choose depends on what kind of weather conditions it'll be used in, such as tropical or dry environments. In other words, you wouldn't necessarily use the same boat dehumidifier in the Great Lakes as you would in theCaribbean or the BVIs. Likewise, a pontoon boat or deck boat wouldn't need the same dehumidification abilities as a large sportfishing boat.
Desiccant DehumidifiersDesiccant dehumidifiers use a chemical usually calcium chloride or Zeolite to absorb moisture. They are built with a fan that pulls air into the dehumidifier and sends it past a wheel that holds the desiccant chemical, which dries the air. Other examples of desiccant dehumidifiers include jars of DampRid and hanging bags of Absorbag.
Compressor-driven DehumidifiersCompressor-driven boat dehumidifiers work like an air conditioner. The air is cooled over the coils and the water condenses, dripping the condensation into a bucket. So, obviously, you'll have to empty the bucket, which is something to consider. Some compressor-driven boat dehumidifiers can be used with a hose for continuous drainage. This is nice for your boat winterization.
Thermo-electric DehumidifiersThermo-electric boat dehumidifiers work without the use of moving parts. Instead, they just have a small fan that circulates the air. Known as the Peltier Effect, it works when an electric current is passed between two different metals. During this, heat gets transferred from one metal to the other, since the electrons pass through different metals at different speeds. It may sound like college-level chemistry, but this type is actually very simple. It doesn't have a humidistat or a defrost cycle, meaning fewer parts equal less worry. And since there's no compressor, it's quieter and more cost-efficient than other types, but it's also slower at removing moisture.
Features of the Best Boat DehumidifiersBoat dehumidifiers have many of the same features as the standard household ones you use in your basement. But here are a couple of marine-specific features you'll need to look for.
- Safety features to protect against electrical or corrosion damage
- Uses a vent, or hose, to release moisture rather than draining into a tank for prolonged and unattended use
- Can be fastened in place to prevent rolling when the boat is moving (boats have a habit of doing that)
