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?

    Yeah we assumed our house wouldn’t have moisture issues being so new. But… If I hadn’t measured I wouldn’t know as we don’t have massive moisture issues. Main issue is condensation on the window frames as they are not thermally broken. Well it is what it is.

    I’ve ordered a 10L dehumidifier, we’ll ventilate more, and let’s see how it goes then.

    It’s not so easy to get onto the ceiling but it’s indeed worthwhile.

      Good luck!

      You don’t have a man-hole in the ceiling in a wardrobe/laundry or other out of the way place where you can just poke a sensor up into the ceiling?
