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?

    Never heard of that, thanks. Our house is built on a concrete slab, so don’t think that will work?

      If there’s an air-gap between the slab and your floor, and you can get in there, then yeah it will help. Concrete is remarkably porous to water.
