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?
4 year old house, double glazing. We have the heat pump set at 21dg on 24x7 all winter and never really open windows.
Current temps and moisture levels:
If you’re worried about moisture I recommend a dehumidifier, those things work wonders and much cheaper than retrofitting ventilation like the other poster mentioned.
I guess it’s worth mentioning, we have a tumble drier in the garage so the house doesn’t get any moisture from drying clothes.
Thanks. Those numbers are similar to ours. We never really opened windows either, we’re aiming to do that daily from now on.
Just bought a dehumidifier. Indeed easiest and cheapest solution.
I’m ok with that humidity to be honest, I am not seeing any mould.
We only a little bit in certain clothes and in the bottom of our alu window frames.
Still above 60% is apparently not healthy. I’d recommend to look into it.
A lot of modern heat-pumps have a dehumidifier mode. But likely if they’re set to Auto they’ll never switch to using it I think.
