Hello everyone, in our living room of 40sqm (430 sq ft) plus a 15sqm (160 sq ft) open kitchen, the temperature is currently around 22°C (72°F) and the humidity level is between 30-40%. The underfloor heating is on, but not in the kitchen. We ventilate 2-3 times a day and do not have a mechanical ventilation system. What can we do to increase the humidity to around 50%? We already have plants, but what do you think about humidifiers? Is there one you would recommend or any other solutions? I mainly notice the dryness around my eyes.

Do you have a ventilation system in your house? For well-insulated and energy-efficient timber frame construction, it is basically a MUST! If not, congratulations anyway! A relative indoor humidity of 30 to 40% is actually good for this. Above 50% is not necessary and already feels uncomfortably “stuffy.” You just need to make sure the levels don’t stay below 30% for an extended period.
To avoid issues:
- No tilted-window ventilation (which is energetically inefficient anyway)
- Morning shock ventilation (cross ventilation) for about 15 to 20 minutes, then close everything.
- Kitchen range hood? Set it to a higher level while cooking and open a kitchen window during this time for fresh air supply.
- In the evening, ventilate again for 10 to 15 minutes before going to bed.
Too much ventilation in dry weather (especially with cold air) brings dry air into the house, which becomes even drier when heated.Is the term “ventilation system” here referring to a unit like an energy recovery ventilator or a comfort ventilation system with humidity recovery?

Do you have a ventilation system in the house? It says there is a comfort climate heating system. That should actually make the question unnecessary.

They can increase indoor humidity by up to 10% with a 3 to 7% loss in system performance (depending on the manufacturer and the system).
