Technology / utility room on the upper floor, opinions?

Patience and the insight that eventually you just hang the laundry on countless racks in the utility room and turn on the heater

By hanging the laundry indoors in the utility room or under the carport during bad weather. Saves a lot of money and is gentler on the clothes.

In frost, without rain, laundry also dries outside. It just has to be dry. (Yes, it eventually hurts the fingers when hanging it up, after all, it’s cold.) The ideal place is IMHO the drying attic, unfortunately the farthest away from the laundry room in the basement, but practically neither exists anymore in modern single-family house new builds...

In the past, when there were still combustion heaters in the basement, laundry also dried very well there. Since condensing boilers take their air from outside, that is also over.

Does anyone have experience with drying in the living area when there is a controlled residential ventilation system (+ heat recovery)? Does that work well? Fast?

You are funny
There is no heating in our freezer compartment - and as mentioned before, it’s a bit colder than elsewhere so the potatoes don’t sprout
In the laundry-utility room there is underfloor heating, yet I still don’t want to miss the comfort of not getting cold hands or having to drive my car out of the carport first.
I already have a small problem drying delicate wash, so now I have a small linen installation on the wall.

Does anyone have experience drying laundry in living spaces with the presence of a controlled residential ventilation system (+ heat recovery)? Does it work well? Quickly?

The controlled residential ventilation system is not intended for drying laundry... it is not designed to dry a whole rack of wet laundry. Possibly and in exceptional cases it does the job with the dry and warm air, but in the long run it would, of course, be questionable in terms of the entire purpose of a controlled residential ventilation system, which is supposed to prevent mold problems.

So at our place, the laundry dries quite quickly in the utility room and can be taken down the next day, sometimes even faster, depending on the type of laundry. The room has an exhaust connected to the controlled residential ventilation system and of course the heating is on there as well (like everywhere else in the house), as it should be, to prevent the house from starting to mold due to too cool temperatures. In the living areas there is usually only supply air, so I would rather not dry laundry there.

There is no rack in the way either, instead we have lines stretched across the room and can hang the laundry very well there, even larger items like bed linen.

It’s always a question of how convenient one is oneself. Of course, it’s easier just to throw everything in the dryer, but for that, we simply thought the space and money were too precious. We didn’t have a dryer in the old house either (it didn’t fit space-wise) and didn’t miss it in the six years. So why would we want to do it differently now just because we have our own house?

The controlled residential ventilation system is not intended for drying laundry... it is not designed to dry a whole rack of wet laundry.

But cooking, bathing, and showering are allowed? In my opinion, the controlled residential ventilation system ensures an air exchange rate (depending on design and operation), whether laundry dries quickly or slowly and whether the relative humidity remains "comfortable" and healthy or not naturally depends on that... The controlled residential ventilation system certainly will not be damaged, and neither will the house, unless the user is completely oblivious (literally). I am more interested in practical experiences, like those reported by Teyla.
