We've got an insulated house, heat it properly, ventilate it, but still see humidity levels of 70%+ in bed rooms. How to fix that? (self.newzealand)

We built a house 7 years ago and it's insulated and has double glazing. I've installed Home Assistant with temp sensors in the bed rooms and seeing 70%+ humidity levels. Temperature is always above 16c

We ventilate it, but still it's 70% in the bedrooms. WHO recommends 40-60%, so we're a bit worried.

Living room is around 55% during the day when we have the heat pump set at 21c.

As it's pretty humid outside I think it's almost impossible to get it lower, but are there any other tips? I don't want to run dehumidifiers. Would an HRV like system help?

I can't speak to NZ, but even a normal tank dehumidifier should have the option for a drain line. It'll usually be a hose fitting hidden above/behind where the tank sits, so you can run a line to whatever household drain is nearby. And if it doesn't already have a fitting, it's usually pretty simple to add one.

It can make placement a hassle since you need to be near a drain, but you'll barely need to touch it beyond setup. It's a huge upgrade from dumping the tank constantly.

Yes, just bought one, and it has a drain outlet. Never knew that. Thanks!
