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?

    As I understand it, dehumidifiers are not a proper long term solution for an entire house; they are recommended for rooms where ventilation is hard.

      You can call an HVAC specialist and get something more permanent, but you need to do something ASAP.

      But you can absolutely get one with a drainage tube and run it 24/7 tho. Lots of people in older houses in America do it.

        Thanks. You mean a dehumidifier with a drain tube? I haven’t seen one here in NZ.

          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!
