Damprid Desiccant in Furnace

urdahere · Post by **urdahere** » Wed. Jun. 01, 2016 1:49 pm

I just bought a tub of DampRid at Walmart. Thought that I would give it a try in my Pocono. As I was selecting it, the old time clerk asked what I was using it for and I told him. He told me, the next time, use SnoMelt or fertilizer. It's the same stuff and that I could get 40# for less than what I was paying for one pail of DampRid.

Has anyone else heard of this or have some of you used this technique?

Thanks,

Joe Urda

Snowmelt will cause rust, at least what Im thinking of. Some fertilizer too. Maybe they were thinking of insulation, like vermiculite?

He did mention to keep it in a plastic container.

After searching MSDSs on the web, the damprid and snomelt, they do appear to be the same material .. if its effective is a ? -- related to particle size ?

LOL, my bad! Brain fart on my part. I should have realized that.

Calcium Chloride is a very common desiccant. It is also used to melt ice.

I get so confused...
How does the Damp-Rid know to only remove the moisture from only inside the stove and to not pull more moisture into the stove than what was already in there?

I'm a thermostat controlled heater/light bulb guy myself. I prefer my moisture quantities to go away from instead of being attracted in towards my precious iron.

Any desiccant is going to reach a saturation point, the bulb never gives up until it dies.

In my own mind it wouldn't do any such "pulling". The moisture is carried by the air. More air would need to be "pulled" in for there to be more moisture. It doesn't make sense to me that it would occur that way.

Lee.

Google "vapor pressure".

Moisture naturally moves from areas of high moisture content to areas of low moisture until it reaches equilibrium. Ambient temperature differences can have an affect on how/where it will move. While air can move moisture, it does not need any air movement to move when there of differences in vapor pressure. In fact it will do the same high-to-low movement in a vacuum.

The air doesn't have to move, the moisture in the air will and it will do it constantly. Air is a medium that water vapour will always try to equalize in. Even if the air doesn't move, the moisture in it will.

I had an open part bag of 'ice melt' type calcium chloride beads in my garage, and when I checked it, it was a soaked and dripping mess. It had become fully saturated and beyond. What a mess.

Myself, I'm sold on the little cubical heater. It maintains my Kaa-2 boiler at 100* all summer, in my cool basement. Turns on & off by thermostat. Every day I walk past the boiler. A quick glance at the boiler gauge, tells me all is well. Come fall, the entire boiler is like it was never shut down.

I use to be a light bulb user. The light bulb does a nice job as well, but never shuts off. The bulbs have also blown on me.

I clean out the stove & black pipe then coat the insides with Fluid Film. Once you close the load door there is no odor in the house & the insides are staying rust free.
