Wet windows won't bit fixed by heating, that will make it worse as the water carrying capacity of warm air is higher than that of cold air.

 

 

That's interesting, and the science makes sense - but we have found that the condensation on windows as actually lessened by leaving the heatpump on low throughout the night. Could this be the result if increased air movement throughout the house not letting it condensate on the windows as easily? If this is the case, would some cheap air circulator fans left running at night help to reduce it further?
