Hello,
I wanted to ask you all, we are facing very hot days again.
How can you cool the house down a bit without using an air conditioner or reduce the sensation of heat?
We can’t simply install an air conditioner because we have a KfW 55 standard and are not allowed to make any changes for the first 10 years, or we would need to hire an energy consultant to recalculate everything.
We shade all the windows during such heat, but we can’t keep all the windows closed. The dog also needs to be able to go into the garden.
What would you recommend?
Should we use regular fans? Tower fans or pedestal fans?
What do you think about fans with humidifiers? Wouldn’t they just increase the indoor humidity unnecessarily?
Are there fans or devices that can actively cool the air, or small air conditioners that don’t require fresh air intake, an outdoor unit, or a vent hose leading outside?
On very hot days above 30°C (86°F), we have about 25–26°C (77–79°F) inside as the highest temperature.

A fan doesn’t cool the air. It only keeps air from becoming stagnant and prevents it from feeling hot AND stuffy. The slow-running ceiling fans, which some probably only know from American movies, are designed exactly for that: quietly eliminating the feeling of still air. Exactly. If we had a ceiling outlet and not such a high ceiling, I would probably have a ceiling fan. Whether it would then perform satisfactorily what it is supposed to do is beyond my knowledge, since I don’t have one.

FrankChief1 Jul 2025 10:28We have a ceiling outlet for a light fixture.
There are lamps with fans integrated.
How exactly do those work? How can you run the fan on the ceiling without turning on the light?
If you switch off the light, the power is cut off, which is probably impractical for everyday use, right?
What do you think about a wall-mounted fan?
Would you say that bladeless fans (like Dyson, for example) are better than tower or standing fans?

Just google ceiling fan with light and remote control.Then the control is only possible via the remote control. Both the light and the fan can only be operated with the remote control, and the light switch must remain switched on permanently.W

If you switch off the light, then the power is off too (which is probably impractical in use, right?)The switch remains on, and the rest is controlled by the remote. It’s not very practical. Two switches are better. FrankChief schrieb:

I couldn’t find much online.
Some were listed as 57 dB, probably at the highest setting, and others often 20 dB, likely at the lowest setting.
