Dehumidifiers

When I had a flat I had a dehumidifier due too condensation.
When we bought our current house we had problem again mainly due to clothes drying (baby clothes lots of them)

I was recommended to install a Nuaire Drymaster 2000 'positive input ventilation system'
wasent cheap but it does what is says on the tin, works a treat no more problems with condensation.

We had a simular type here already when we purchased the property. We where told it was great for condersation... at a cost of 700pounds 11 years ago...we find it really drafty even on low setting... but great in a heatwave acts a bit like air conditioning to me.
We however have never seemed to have had a condensation problem as in wet windows...but then we found two rooms had some mould on the walls and purchased two delonghi dehumidifiers after a friend had same issues and that really solved the problem. Dianne

I've got one of these

It's a desiccant type. I've never tried the compressor type, but I think if I had to buy another one I'd probably go for the same again since they are more efficient at all temperatures and they don't sound like a fridge with a fan attached.

In my house (3 bed semi) it fills it's tank in around two days. Not sure how much it costs to run, but I never noticed my electric bill rise much when I started using it. At this time of year I normally leave it running on it's 8-hour timer starting when I leave for work in the morning.

The best part for me is the drier air feels more comfortable and I don't have to have the heating set so high to combat the damp feeling in the air. I think the saving on heating more than compensates for however much the dehumidifier costs to run.

I did look at that one but was unable to find any manual on it. You don't know where I can get the manual from do you?
Thank you.

No, sorry. But I can probably tell you whatever you need to know?

Having many years experience with dehumidifiers i can say without doubt that the new dessicant type are far better than the old compressor based models and i have both.

The difference is that the dessicant based designs can operate down to freezing with little or no effect to their efficiency. The compressor models can only operate down to around +5c.

There is also a significant difference in noise levels.
I have Amcor and Ebac compressor based dehumidfifiers and they are both quite noisy.

I also have an "EcoAir DD122FW simple" dessicant based model and on the mid range settings its almost silent. Its also about a third of the weight of my compressor based dehumidifiers.

In short if and when i do have to get another one it will be another dessicant based model. Take a look at the above EcoAir model and shop around. You won't be dissapointed.

Power
As is the case with all desiccant machines the running wattage of the DD122FW-MK3 is higher than that of a compressor based machine. But one has to take into account the fact that desiccant machines get the job done faster and are therefore on for less time. The end result in terms of consumption is very similar.

Important Information: Ensuring adequate air movement improves effectiveness of the DD122FW Simple dehumidifier, for this we recommend the use of portable fans particularly for confined spaces e.g. cellars and small rooms


I noticed above information...........
They are more expensive to run and the addition of an extra fan is stated as required if in a small room/area...that would put me off for my requirements but it certainly is worth knowing about. Dianne

Fans draw about 30watts and the same argument could be used to make a compressor dehumidifier more effective

The power consumption of the DD122FW according to the manual is 620w however that is on the maximum level and so far i have never needed to use that setting. I use it at a mid range setting where it draws 390w. At this level it costs me 34.6p a day to run if it were on constantly for 24 hours (this assumes a unit price of 9.15 Kwh). In reality it actually consumes 2.75kw over a 24 hour period so costs 25p a day to run.

How do i know this ? because i had it plugged into one of these for a month to monitor its power consumption.

This compares very favourably with my 370w/800w Amcor HD320.
