Flushing it helps, try closing the return side to the system and drain water from the manifold while also filling it from your heater, hope you got a drain nearby tho because you gone flush every loop by its on for bit after and presumably you did it right and long enough the air should be gone and it's as quiet as it gets

I build a few water-cooled systems in my life and I know where you're coming from but this is a bit different, instead of fins a heat pump uses a plate heat exchanger and all pipes are at least 22mm wide, a thin bacteria film would do basically nothing in the grand scheme also because it's desalted water there are just a few bacteria colonies left that gone die in an "airless" (in quation because it's in an engineering sense airless not in an physical sense) system without any food in a few weeks to days. Also an anti microbial agent could be aggressive against some materials in the loop and one that isn't should be rather expensive. Especially in that volume of water. We're talking about an office building with an attached workshop. Together with the buffers it should add up to 3000l of water in circulation. Having roughly 10% of an agent that is probably expensive and really doesn't do anything would be not that efficient.

TL:Dr: cost/efficiency factor isn't there to begin with

Well letting us put the taskbar on top of on the side is to hard but breaking everything else with ai integration is quite easy lmao

Well electricity costs around 0.30€ per kWh and you need at least 4-6kw to heat that area and a heat pump that produces the same amount of heat uses 1-1.2kw of electricity for the same amout of heat. And well a fireplace is under heavy regulation here in Germany because of the dust and emissions.

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 

I mean I work since 10 year in this job and I never heard of any spontaneous leaking and well we never thrown a system out because of that

Here in Germany we never really got earthquake and even the hardest we got in the last hundred years just rattled some roof tiles off. Also it's very common in Europe to use floor heating (due to the lower temperatures you need to provide and such beeing more efficient with heat pump)in neuer buildings so mostly everyone does it

Just desalted water from our osmosis machine 

its 20mm /3mm PEX pipe

They are 17 individual loops it usually takes up to a day till the floor has its initial temperature after that temperature changes take not longer than 30mins

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)

The hallway itself doesn't has a loop on it's own so we heat it with the entrance pipes of the different rooms
