ᐅ Air-to-Water Heat Pump: Current Consumption and Data

Does it say anywhere that I’m doing something different? 😉
My concern is that the relative humidity rises back up to (sometimes above) 60% after a short time.
I don’t have this issue in any other room. Not even in the small bathroom or the utility room where damp laundry is drying almost 24/7.

In our case, cross-ventilation cools the temperature down from 23-24°C (73-75°F) to 16-17°C (61-63°F), after which it quickly rises back to 23°C (73°F).

Sorry to say this, but something isn’t right. This has nothing to do with residual moisture, especially since it’s only one room. There are only two possibilities: something is leaking or damp. Insulation? Plumbing? Process of elimination…

I think the issue is simply that the ventilation isn’t done properly.

Open the windows 3-4 times a day to create a cross breeze. You need cold air that can absorb the moisture. If you only ventilate from about 23.5°C (74°F) down to 21.5°C (71°F), it hardly makes any difference.

Even if you don’t ventilate at all, having 23°C (73°F) in the bathroom and over 60% air humidity is unusual. Just imagine how much water vapor is in the air. That can’t come from just one shower.

That could be accurate, you have 2-3 traps, damp towels, the plaster absorbs a small amount of water, possibly damp bath mats, etc.

In any case, ventilating to reduce humidity in the air is practically useless if you only manage to lower the temperature by 1-2 degrees Celsius (34-36 degrees Fahrenheit). Given the current outdoor temperatures, it’s hardly possible to get rid of the moisture more easily.
