The main reason is to lower the humidity in the house, which is damp due to bad insulation from the ground etc. By sunrise the humidity in the rooms was ca 65% RH, but now 3 hours later it is down to 40% RH. Temperature wise one needs a lot of air with 40-65 c, blowing into the house, to raise the temperature a few degrees. First time this summer/autumn my room temperature went down to 21c, but will be ca 25c late afternoon though...
There was more wind all day long, then yesterday night in my area..
