No condensation tho. Now it's 19.2C/21% but
everything still feels cold. Perhaps it is my
own immune system...


I'm currently at 15.6C and 42%RH inside and quite comfortable. At
19.2C, it's still a little cold, but with such low RH, you should be
feeling only slightly cold.


Emanuel should keep in mind that his 19.2C is air temperature. If it's
much colder outside and if the walls have too little insulation, their
surface may be significantly colder. In that situation, one's body loses
heat by radiation to the cold surfaces. That can be quite uncomfortable.
It's the opposite of the comfortable feel one gets from the radiant heat
of a fireplace or similar source.

Over one winter I worked in a tiny company sited in a huge concrete
block building, a former auto body shop. The lab areas had no heat
except a radiant tube heater up towards the ceiling fueled by natural
gas. Despite the low air temperature (maybe 15C) it was quite
comfortable under that pipe. But anywhere else in that area, one felt
chilly indeed.
