Condensate Drain Winter

Yes, after I saw the gravel in your picture, I already thought about using a different (more permeable) gravel. At the moment, my eaves strips are filled with 0-16mm gravel (crushed stone), which is probably not optimal. It would probably be better to use 16-32mm round gravel, which creates more voids. What kind of gravel do you have and how high is it piled up in the eaves strip?

Sorry Bieber, just saw that you asked for a picture. But unfortunately, there wouldn't be much to see with me like with you. The outdoor unit stands directly on a concrete base, and the drain hose goes straight down into the pipe inside the unit. There is nothing visible from the outside.

Edit, here’s a quick picture where you can roughly see it:

What kind of gravel do you have and how high is it piled up in the gutter strip?

Definitely 16-32 mm. I don't know the pile height, I would have to look through the photos. Coarse gravel (16/32) is definitely better suited. The base area should not be exposed to stagnant moisture.

Hello everyone,

for our new construction, we are getting the Stiebel WPL 10 AC outdoor unit.
What is the experience with ice formation on and around the unit?
I was told that in winter it can lead to the formation of an "ice rink."

We will definitely connect the condensate drain to the rainwater drainage to let it drain in a controlled manner.

Is there actually a minimum distance to the neighboring boundary for the outdoor units?
