Hello,

Regarding the current situation: an air source heat pump with an outdoor unit mounted on a standard base and frame, placed on the gravel fascia strip at the house.
Now, in winter, I have already ended up with quite a large “ice rink” due to the freezing condensate.

What are your experiences or ideas to prevent or reduce this? Drainage, connection to the drainage system...? I would not favor heating...

Yes, after seeing the gravel in your picture, I also thought about using a different (more permeable) gravel. At the moment, my eaves strip is filled with 0-16mm (0-5/8 inch) gravel (crushed stone), which is probably not ideal. It would likely be better to use 16-32mm (5/8-1 1/4 inch) rounded gravel, which creates more void space. What kind of gravel do you have, and how deep is it compacted in the eaves strip?

Sorry Bieber, I just saw that you asked for a picture. Unfortunately, there wouldn’t be much to see on my side compared to yours. The outdoor unit is placed directly on a concrete base. The drain hose goes straight down into the pipe inside the unit. So, nothing is visible from the outside.

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


Sidewalk next to residential building; to the right a gray distribution box, in front of it a black garbage bag.

Definitely 16-32 mm (5/8 - 1 1/4 inches). I don’t know the fill height, I would have to check the photos.

Coarse gravel (16/32) is definitely more suitable. The base area should not be exposed to any standing moisture.

Hello everyone,

For our new build, we will be installing the Stiebel WPL 10 AC outdoor unit.
What has been your experience with ice formation on and around the unit?
I was told that in winter an "ice rink" can form.

We will definitely connect the condensate drain to the rainwater drainage system to ensure controlled runoff.

Is there a required minimum distance for outdoor units from the property boundary?
