What's your humidity like?

16c and 57% humidity. Normally see it around 65% when I turn the heating on to 18c. Never goes above 18c (I might treat myself to 19c for Christmas!)

1960s build with timber insulated dormer upstairs. Cavity wall insulation downstairs.

The structure of your house will thank you for it as all the materials used in house building absorb moisture like a sponger (timber, plasterboard, carpets, curtains etc).

The science is called latent heat .. https://en.wikipedia.org/wiki/Latent_heat

Dreading to think how much hard work it's going to be for our dehumidifier when our furniture comes back from storage in a couple of weeks time. It's been in an unheated shipping container for 10 months. Didn't expect it to be this long. Have been trying to dry the house out that has been completely replastered and some new floor screeding.

Shipping containers can be nasty as they are unventilated. I'd be tempted to rent a couple of industrial units from a hire shop for a couple of weeks to get everything dried out nicely.

17 degrees and heating on for a couple of hours a day… humidity varies between 64% (iif we have opened windows and it’s dry outside) and 80% if it’s raining outside.

similar humidity levels in October when it was 19-20 degrees indoors and no need of heating.

Heating has been on at 18 most of today, and window open slightly at times too for air flow, as we had a visitor… 

Does the visitor know you have to open a window when they call round ?

It’s been a solid 23 degrees in Ladbrokes today.

19-20C throughout the day and relative humidity is 45-47%.

We have extractor fans that run 24/7, very slowly taking air out. In this very cold weather the outside air holds very little moisture and I can afford to close all except a couple of trickle vents without the house becoming humid. We run the kitchen extract fan at full speed when we cook (usually twice a day).

It's easy to overlook humidity and think only about temperatures. But a damp home is unhealthy for humans and buildings.

Today the outside  air temp is 0c & 100% humidity, once warmed to 18c in our house that air has a RH of 31% , we have all windows & vents closed but vent the house by opening one window downstairs  & 2 upstairs once a day for 5 mins at this time of year , the inside air is starting to feel too dry for me now.

My son lives in Sweden & has to run a humidifier 24/7 as the air is so dry in winter.
