Trotec dehumidifier

September1

I have a bit of humidity problem in my house, which is a big trouble in winter as ventilating means also heat loss. Anyway I had used dehumidifiers for quite a while know, and as they seem to break in a year or two I recently got a new one from I think German company called Trotec.

That is a best value dehumidifier at this price range, as there is hardly anything that has specs for 24l / day collection at this price point. On amazon they have only three dehumidifiers, but they have web shop and they ship to Ireland where much wide range is offered:

I have also eBac 2850e which is really good dehumidifier as well, but it costs twice and has only specs for 18l / day collection. However specs for humidifiers are made at 32(ebac) or 30(trotec) degrees C and I think 90% humidity, which is not so common. It also means that it is very hard to compare them, so to satisfy my curiosity I ran them in same room at MAX settings to see which one would collect more water. 2850e collected about 600g and Trotec about 1.1kg, so at this effiency of actual use I think that is really good bargain. Having said that eBac has really smart control system.

Not sure of how it compares but lidl had one last week. It was about €139 and was 420w I think. Had 4 in swords yesterday. Looks around the same size as this one.

If your dehumidifiers are only lasting a year or two- they're not fit for purpose, and I'd be bringing them back. I've been using the same one for 5 years now. Once I clean out the filter every few weeks, its as good as new. Even using it pretty continuously for weeks on end- doesn't matter to this machine- mind you it only extracts about 10 litres a day, no more.

Both I have now running are using about 200-250W when compressor is on, on traditional dehumidifiers there is a weak dependence between extraction rate and power usage, both do not keep it running all the time. eBac is now year without fault, I will update in future on Trotec reliability.

Not sure how good LIDL one is, it uses a bit more power like desiccant one, but 20L is typical range on compressor. As I mentioned earlier, ones I could dest would differ only 33% on paper but 83% in real operations.

Exactly. And that's also the reason why I wouldn't use a "traditional" compressor type dehumidifier in Ireland. They work well as long as the temperature difference between the cooling element and the room is enough to trigger condensation, hence they are rated at really high temperatures. At lower ambient temperatures their efficiency drops significantly, while desiccant humidifiers are largely unaffected by the room temperature. They use more energy than a compressor one, but in a real life scenario they typically also extract a lot more moisture in a shorter time so you don't need to leave them on for as long a compressor one for the same result.
I have been using one of those for the best part of three years now and it really does the job and it is even cheaper.

I had three EcoAirs failures, I still have one broken but as it is now outside warranty not sure what to do with it. Anyway both 18l and 24l compressor ones are more efficient at my typical house temps (17-19C). If I fix my ecoair I will run another test to confirm it. Power draw was higher on Ecoair so if you think in Euro per litre extracted they might be not as good value.

I wouldn't recommend any Trotec products as I bought small dehumidifier from them (http://www.trotec24.com/) and it broke ONE DAY after 2 year warranty period. Quite impressive precision in lifespan design, but you have to be aware it will work only as long as 2 years.

Electronics in ireland are protected for up to 6 years under Irish law - I have had many repairs over the warranty period.

I've a small one brand is 'Challenge'- its a 20 litre jobbie that I got in Argos of all places- I'd guess at least 6 years ago at this stage. It was on special at the time for 199.

I also have a much larger one- with all the bells and whistles- it free drains into an outlet- its as big as an undercounter fridge- and it also airconditions. That one cost around 280 and came from Aldi of all places. It has separate heating/cooling functions- that work really really well.

I only tend to use the smaller 'Challenge' one- as the big one sounds like an airplane trying to take off (and it will quite happily knock things over (clothes horse) or send tea towels etc flying. The big one also is plugged into the kitchen air extraction piping- but is technically mobile (as in- its on wheels). Its a bit of a monster though- and takes at least 2 people to lift it. Another reason for not using the big one that much- its got an E energy rating..........
