Positive pressure is definitely not as good. But if you plan ahead you can always modify into a balanced system later. In my last house when I installed positive pressure I also added an additional vent in the soffit in case I wanted to turn it into a balanced system in the future. But the positive pressure solved the condensation problem so didn't end up upgrading to balanced. You could also do balanced without mechanical heat recovery.
Maybe as an experiment try blow a fan pointed out an open window and see if it makes any difference to the humidity?
Thanks again for all the tips, much appreciated! I learn more and more about it.
Yes, will try the fan.
What type of system did you install? Just a simple fan or a more sophisticated one? If you want to be ready for balanced I guess your fan needs to be ready as well?
I installed ducted air con and instead of having a separate system for ventilation, for cost effectiveness I routed it from the outside through the air con system. So the aircon pulled the air from both the return vent in the house (90%) and from the outside (10%). You only need a small amount of mechanical airflow from the outside to reduce moisture levels. And had another vent hole with cover on the soffit for future but not ducted into the air con.
