Low heat to avoid condensation

[Golan]

I live in a small flat in London 4 radiators 1 living room 1 bad room

1 hall and one in the bathroom. I read a lot about condensation and the fact that it is important to have a little heat in unused room in order to avoid it. The radiator in the living room and in the bath room are fully open and the hall radiator is 10% open just to nice warmish heat the room thermostat located in the hall and control the house temperature My question is it needed to have the radiator in my bad room on low heat to avoid condensation ? or is it only on extreme cold days which will come only in 2 month. Most of the time the door to the bad room is closed when the heating is on and if the door is open the heat from the hall and the living room worm the bad room to a nice temperature, So I don't see a reason to have the radiator on in that room and use more energy Thoughts ?

What room temp condensation occurs at depends on interior RH, temperature and insulation. If youre getting condensation, heating can sometimes solve it, but is a pricey way to do so. Much cheaper is a humidistatic dehumidifier. Addressing the sources of damp and ensuring you've got adequate ventilation also sometimes cure it.

Sometimes damp is caused by inappropriate building maintenance. Old buildings can be prone to this one. More info would help.

Is that like SuperNanny's naughty step? How often do you have to spend time in there? You'll probably be huffing and puffing a bit if you've been sent to the bad room so your breath may cause extra condensation. Try to warm the room a bit before you are naughty and open the window a little for ventilation to help you cool off.

Prevention is better than cure...

[meow2222]

thats true for situations where cure is much more difficult than prevention, or the result of the possible problem is severe. Neither apply in this case, if theres no condensation theres no reason to take action.
