Hi guys, this is bugging me to no end. The power this pump is consuming during idle periods. It’s unbelievable to be honest because there is absolutely no reason for that. I found one guy with same pump. In summer only DHW and look at this…
Another guy (this is same as mine):
Simply randomly the pump decides to draw 100W (I have 63W). For what ? Where’s that energy wasted ? During a course of 24h in summer when you have one or no DHW cycle this burn 2kW of electricity. So poor guy’s DHW efficiency was COP2.65 but at the end he ended up with COP close to electric boiler heating, wtf ?? What is the reason to have pump for DHW in summer ? You know why my rant on Samsung is so sensitive here.
I have suspicion that Samsung uses it for some crypto mining or something like that. Yes a conspiracy but explain it 
Thousands of installations like this can generate something.
Also seems only Gen. 7 with R32 are affected. Seems R290 are not. This R32 generation is fu**ed so badly to be honest that Samsung should replace it for free with R290. No jokes.
