An outdoor heatpump unit pulls water from the air since moisture condenses on its cold radiator. In very cold
temperatures it forms ice, which is suddenly thawed all at once in a 'defrost cycle'. Our outdoor unit was installed
over our driveway, and we walk under it on the way to our back door.
The installer did not place a capture tray, but I want to avoid water dripping and pooling on the
driveway during the heating season so we don't get a slippery ice spot or perhaps the
continuous flow of water might even find its way into the brick wall.
After having the rainwater tank installed and connected to the roof,
there was still quite some plumbing missing. The filter and calmed inlet
add up to hundreds of euros. In my case the way the tubes were
connected to the tank made off the shelve filters unusable, so I opted
to DIY everything.
While designing a screw-drive based RC tank (perhaps more on that later), I wanted to create a large easily customisable support structure out of a minimal amount of plastic.
I started prototyping an interlocking structure in the shape of a octothorpe (#).
This turned out to be a lot of ugly code, and so I got sucked into rabit hole of optimising my openscad model and found a cleaner solution.
