It is purely to see what the thermal is like in build up and loss as an experiement. It will remain cold as needed otherwise. Just interesting to see how effective it is. Also the temp is not the critical element if you control humidty and moisture. Mold cannot grow without such. If you are cooling and heating a space over a few hours you need to control any moisture build up such as condensation on windows and the general humidty.That’s a recipe to get mould. Either keep the house cold or keep it warm, but don’t heat it for short periods as mould will thrive in those conditions.
