Our house is down in the woods in a little valley, so with the lack of sunlight, you can imagine how damp it can get back here in the spring/summer/fall. At any rate, I have been looking into purchasing a dehumidifier. Apparently, they no longer make dehumidifiers with freon as the refrigerant- some other chemical named R-410A (and there are some other ones too I believe) are used b/c freon is ozone-depleting. That is all well and good, but after reading reviews and gathering some info, these new dehumidifiers with the newer refrigerant all seem to conk out after 1 year of use, and the warranty period of all the units is 1 year of course (except for some Danby models that have 2 years but apparently horrible customer service). The issue seems to be that freon had a lubricant that allowed the units to run without freezing up for years and years (my parents have an old GE that has been running for 20 years).

I could get an extended service warranty if I bought one of these things- Home Depot offers one for 4 years for 100 dollars, Lowes offers an extra year for 25 dollars and Best Buy does not offer extended warranty plans for dehumidifiers. However, I prefer to buy something that will last a bit longer. This is a last ditch option.

So I decided to see if there were any alternatives to compressor based dehumidifiers. Aha, yes there are! Desiccant based dehumidifiers! We already own a couple of non-electric ones, but apparently they have electric ones that uses a fan to draw in the air and heat to pull the water away from the desiccant. I checked the price of the units.. hm, they were listed in GBP.. OK, not seeing any in USD.. Ah, of course, for some reason, they do not sell these type of dehumidifiers in the US! They sell the $1200 whole house desiccant based models, but none of the smaller units.

This whole thing is very annoying, to say the least. I am all for green technologies. However, when your green technologies end up sending more crap to the landfill, I fail to see how it is truly a green technology. Also, why is it that somehow we in the US cannot purchase a simple electric desiccant based dehumidifier? It isn't like this is new technology. Does anyone know why these units are not for sale in the US? From what I understand, they are about as effective as compressor based dehumidifiers and much more efficient and "green" as they use less energy to gather moisture and will last for a long time granted the parts used are not made of 1 CM of plastic.

This is not news, but it seems fairly political to me as it represents issues with green technology, or possibly just abuse of the "green" mentality in combination with capitalistic manipulation, i.e. suppression of products that might be too competitive against inferior products currently in the market.

That said, if anyone can find an electric desiccant-based DH that is not a whole house unit that is available in the US, I would gladly remove this wordy post with sincerest apologies :D

Where do you get the idea that dehumidifiers only last one year? If it was because of the new style coolant all our A/C (home and car) and refrigerators would only last one year as well. I call shens on your basic underlying premise.

And you are also leaping to conclusions without the least bit of evidence presented that the electric desiccant dehumidifiers are banned in the US.

I think your conspiracy theory, as wackily inventive as it is, with all the typical paranoid thinking of folk who feel helplessly manipulated, a product, you understand, of a traumatic childhood, is not a correct theory and the simple facts are that a technology like you wish for is not doable economically in a small package. Like an indoor air conditioner, you would need to vent the water out of the portable unit to the outside of the house. Also there are different levels of green. Products that last a year are one kind of anti green. Chemicals that cause global warming are on a different scale and a far bigger catastrophe. Waste, at least, can be recycled. And it looks like the whole house thing is what you need.

I had a DeLonghi DNC65 when I lived in Hong Kong. I used it for a very small studio flat (always very humid year round) and it worked great. The only noise is from the fan, which when set on low is fairly quiet but a bit loud when on the normal setting. The only problem with them is that they use a lot of energy. They have to run a heater to extract the water from the desiccant. So it uses more energy and heats up the room more than a standard refrigerant dehumidifier. For example, that Delonghi uses 500 W from the data on their website but their refrigerant ones use 250 W or less (a comparable unit uses less than 200 W).

On a related note, any of you unemployed up and coming entrepreneurs, now is the time to get in on the bottom floor of selling bottled air, maybe plastic balloons of it filled in death valley.

No, they have a drainage bucket so you don't need to drain outside. You probably can get them with a drainage hose as well, but since they don't have them readily available in the US, I did not look over the details too carefully.

Also, you did not actually follow what you searched. All stores are not located in the US. One of the stores delivers to the US, but is located in England which probably = big bux to ship). Ordering on the site is suspended though, so I can't check shipping prices.

Try the UK Amazon.com website. They carry Delonghi products.

Don't forget to check on the room size intended for the models.

Where do you get the idea that dehumidifiers only last one year? If it was because of the new style coolant all our A/C (home and car) and refrigerators would only last one year as well. I call shens on your basic underlying premise.

And you are also leaping to conclusions without the least bit of evidence presented that the electric desiccant dehumidifiers are banned in the US.

http://www.askmehelpdesk.com/heating-air-conditioning/410-puron-vs-r-22-refrigerant-31482.html

In our research at the lab at NKU many years ago it was found that 410 had a few problems that 22 did not have. The oil used in 410 is hydroscopic. That means it sucks up water like a magnet and this is a major problem with refrigeration/AC systems. R-22 uses mineral oil and is not near the magnet for water as oil for 410. When you install this stuff you better wear surgical gloves and be quick about your brazing. During brazing a nitrogen flow is necessary to prevent contamination and that holds true for all refrigerants but 410 is more sensitive to this.

http://webcache.googleusercontent.c....aspx+r22+vs+R-410A&cd=21&hl=en&ct=clnk&gl=us

You can do a search on r22 vs R-410A

It does seem that more people are for the newer refrigerant. I read so many bad reviews of the dehumidifiers breaking after 1 year that it got me a bit concerned. I wish they would do a longevity test on some of these units... The only longevity reported is that of breaking units. You don't read of anyone saying "I had this unit for 2 years and it is running great!" The good reviews only mention running the units for a week or so. And I have nothing to go by except the reviews....
