At the end of the day it's physics, warm air condensing on a cold surface, warm air holds more moisture than cold air.

From Wiki

"The dew point is the temperature at which the water vapor in a sample of air at constant barometric pressure condenses into liquid water at the same rate at which it evaporates. At temperatures below the dew point, water will leave the air. The condensed water is called dew when it forms on a solid surface. The condensed water is called either fog or a cloud, depending on its altitude, when it forms in the air."

"Relative humidity of 100% indicates the dew point is equal to the current temperature and that the air is maximally saturated with water. When the moisture content remains constant and temperature increases, relative humidity decreases"

Control that lot and you're there !

So with my dehumidifier I keep the relative humidity below 50% whatever the temperature and that's mostly to keep my wood right but also keeps rust at bay. If I put my wood burner on the relative humidity can drop to low 40's%

Do you have a fancy dehumidifier?

Would something like this work ok, it appears to have a low power usage so I could have it on all winter doing its thing.

This one,

A bit high wattage but the built in humidistat only brings it on when required. It also has continuous drain so no need to keep emptying it.

I can't remember where I saw it but there's web sites where you can determine the size of dehumidifier required for the volume of your space.

There was a grand designs last week about a guy in Ireland that clagged together 4 containers and the finished article was very nice, foam spray is the only way to go you want no air gaps @ all and all steel must be covered ie main support framework or you will get a thermal bridge, with a dehumidifier as well it should be fine.

Yeah that was fantastic, cant believe he spent 14k on a bath!
