Jag bor i Finland och har Carrier 30 NQ C9NH värmepump. (~IVT modell Greenline Plus C9). Maskin är 12 år gammal.
In december 2023 all three flexible hoses were replaced with "original" new ones. They were quite clogged. The delta T dropped from 9-10 C to 6 C degrees after this.
I put aluminium tape around the new hoses so that it would prevent the diffusion of the oxygen through the hoses.
Now I got little nervous that was that good or bad thing to do. I am worried that now when flexible hoses are better against diffusion some other place can get clogged. (The flexible hoses can be changed/cleaned but other places are much harder to clean/replace.) Whats' your opinion?
TACK!
No worries ☺️
You can clean circulating acid with a 2nd hand pump, IF you see that your delta 6° is increasing. I did clean my heat exchanger a 2nd time as preventive, it was just a little dirty inside.
I also mounted a magnetitfilter 8 yrs ago, but from my water there is nearly nothing collected.
