Optimistic figures. Certainly got my attention.

Re: Samsung mono block heat pump
Very poor and ambiguous article, journo racing to meet a given time perhaps, suggests outdoor temp of 35C in one place and 43C in another, if is 43C outside then I would imagine a COP of 5 would be achiveable without producing 75C DHW.
Re: Samsung mono block heat pump
Also if you copy n paste the model no and read on other sites the numbers vary. That actually makes it closer to real for me!
The 39% larger heat exchanger is what I liked for practicality but also an indication of type development.
If I could get a cop of 3 in Winter I'd sign up. As is I'm on Octopus list for when they are installing in the North.

Re: Samsung mono block heat pump
Propane has always been a fantastic gas - even with low charge systems. You often see it mixed with isobutane or ethane to bring up performance - your little mini drinks fridge because is often completely propane or isobutane where the flammability isn't too much of an issue due to the very low amount of charge.
Hopefully we some more sense around using A3 systems in houses - the challenge has always been the possibility of zone 1 classification for wot you've designed meaning special flame-proof requirements. So the relaxation of f-gas to allow this is great.
You'll notice this block most likely will have a very high compression ratio, probably beyond 15 or 16 - but you need to check that you are comparing EN14825 testing as its done at 35C even with R290 - it will also be a new compressor design (probably copied from a isobutane unit).
https://midsummerwholesale.co.uk/buy/sa ... -heat-pump is the R32 version.
There are some other nice things about the design, the base of the unit is raise from internal struts so wont rust out etc.
Samsung are interesting in that generally anything above 15kW gets scroll compressors and anything below gets rotary...
IMO anyone promoting weird blends or new gases is a part of "big chem" especially when natural gases are so performant, don't deplete ozone, abet flammable.
