I am no expert but to the best of my knowledge it depends on your property and how much you heat it up and then how much heat is lost during the time the heating is off.
Basically the principle works on keeping the heat ticking over at temperature x say 18-19 C will only require short boots of the boiler, however if you put it on for a couple of hours in the morning it may only just reach that temp after 2hrs of the boiler on constantly then in the evening the same thing 2 hrs or so of flat out folloed by short burts till it goes off again. Also by heating and cooling all you would do is draw out some of the moisture then move it on to condensate somewhere else when the house cools again.
Do you normally only heat your house to 16 celsius?
My understanding is that you want to heat the house up – structure and all while offering paths for the moisture to escape. Could there be the possibility that your house is simply not getting warm enough to dry it’s self out?
