I'm the installer lmao. We got a system with an high power pump cycles every loop multiple times and dumps it in an open container before we connect the heat pump
So, dumping it into an open container is a way to remove bubbles from the line? You wait for the water to come out without bubbles, and that means the line is full? How do you connect the pump without introducing bubbles? Is it submerged in the open container? Then you pull the line down into the water as it's running and connect it?
It's an open container and a submittable pump (usually used for lifting ground water from 100m) that pumps it from the bottrem of the container into the loop and when it comes back from the loop it gets dumped on top of the water line, since the pump transport around 3500l/h we let a single loop with roughly 5-15l circulate for roughly 15mins before we switch to the next (English is my second language so please ignore the grammar mistakes)
What is the final fill liquid? Is there an anti bio/anti corrosion agent?
Just desalted water from our osmosis machine
Not worried about anything growing in there?
I mean it's an "airless" closed loop with 95% clean h2o. The water may gets darker after time from bacteria dieing but there will probably never grow anything concerning
