currently Belfast humidity is 84%
that explains 80% humidity in my loft then , by the looks of it no point getting the Drimaster even though I really wanted to

Wrong, Google relative humidity. Once air is warmed up to say 20/21 the relative humidity goes down. Only if you lived in a tropical rainforest would it not be beneficial.

Cold air reaches the dew point very quickly hence we have cold moisture on windows and other surfaces. Few point is 100% humidity where water condenses out of the air. So cold air at 86% is not far off that 100%. If you warm that air up the humidity level drops it then means the air can hold more moisture so the relative humidity will drop down to approx 45-50% meaning it then can hold more moisture as you've increased the amount it can hold.

OK, I will do some experiments tomorrow, will check the actual humidity outside in my garage and loft

I have noticed your second update, does it not mean though that when you are heating the cold air with high humidity you are actually spending more energy to heat the water vapour, what I am trying to say is that I did read a lot about the drimaster, but what I don't want to do, is spend couple of 100 quid and actually do more damage i.e. get more moisture in the house.

Obviously it costs to heat cold air from cold. But it naturally reduces the humidity level when you do heat cold air. Look at how you demist your windscreen on your car by blowing warmed cold air from outside at it. The difference between heating cold dry air and cold damp air not noticeable. As soon as you warm that air inside up it becomes able to hold more humidity thus drying the property out.

Just checked here it's 90% @ 2.3% outside and inside our bedrooms it's 38% @ 18c. Our bathroom is 53% @ 19.5c and that's half an hour after someone showered last.

Downstairs is at approx 22c and is at 50% humidity. Well within the comfort zone.

thanks for the details, if you have drimaster by any chance, can you check the humidity and temperature close to it. that s would probably push me over the edge and I will bite the bullet

Yes I have the drimaster heat the heater is only used for 4 hours a day 2 in the morning and 2 at night. The bedroom reading is taken closest too it about 2 metres away. I'll put the sensor on the landing though tonight and report a reading back in the morning for you.

Thank you I really appreciate it

Landing at 16.8c and 48% - please note the heating has been set to 18c when we went to bed so landing has dropped. Usually about 19c when set to 21c.

thanks, for the details, I have one last question if I may, if I understand it right this reading is from inside of your house where your drimaster is pushing the air into the house. what I was wondering is, what is the humidity where the drimaster is actually sucking the air from (in my case it should be loft area, which is currently more humid than the house)
