Treating High Humidity in basement


Hello all,

We have moved into a new house and my system is in a basement with floor heat. I have high humidity in this room, sometimes 68%. What is a good dehumidifier system to use for when I am not in the room? I have ventilated the room for up to six hours which lowered the levels to 59%, what else should I do? Should I turn the floor heat off and turn the room into an iceberg and vent the windows in the evening before I use the room? Thanks.
PS. I am located in Germany

Lat year I worked at construction site of the ROM.That is the Royal Ontario Museum and they expanded the facilities with this enormous addition that went over budget.$$$$
They called the new part "Crystals",because the roof lines look like inverted pyramids or something.Anyway it was the most difficult job that my local union of Glaziers and the local union of Ironworkers had been on,we were overwhelmed(we joined forces to deal with the challenge,110 guys on 60 hour work weeks to finish it),a nightmare of engineering ,over complicated,overkilled ,overdesigned and extremely labor intensive.All material were designed,engineered,manufactured and shipped to us from Germany by a company called "Gardner Glass" the company that did the work here was "Permasteel-isa" the company that did the structural steel erection was "Walter"the general contructor company was "Vanbots".Even down to the last bolt and tiny screw ,everything was shipped from Germany.Funny we HAD to use the German silicone called "Stabalux" and we went through it so fast that we were running out very often ,so our foreman suggested we use the Canadian commercial silicone instead" well, when the German big shots found out,they made us strip all the cured silicone,power brush all the galvanized metal gutter systems and reseal with Stabalux.!!!They wouldn't honor the warranty otherwise!! We had one of our union member by the name of " Kurt"in charge of the supplies and materials because he was a German born and he could read and translate the labels.LOL.I mean the labels were only written in German,no English on them!
I was impressed with the German quality of materials and design.Truly genious design I must say.No corners were cut with anything ,we had visits from German architects to overlook and ensure the project went smooth.
By reading the description of your home I understand that your house is very "tight" and does not "breath" .I renovated my home recently and I got the same problem.Here in Canada we install a vapor barrier on the warm side of the insulation and drywall right over it.Any moisture generated in the house can not penetrate the wall and get in the wall cavity where in time can cause damage to the wood structure.I DID such a perfect job of sealing my home that I get moisture on my glass windows too.An HVAC guy that came to my home said that usually a 10% wall area needs to stay unsealed .I went 100% myself.I use a dihumidifier at the moment set at 50% relative indoor humidity.If the unit is off,my indoor humidity rise to 67-70%.I seen it even higher like 75% last winter.
When I get around to it I will call a specialist to come and in with a better solution to the problem,but dehumidifier seems to work for me at the moment.
