Heat Pump
There's a video on youtube of a guy using an old R22 or R270 air conditioner modified as a heat pump for water heating.
I was wondering if any of you guys made something like this, as I can only find comercial links for heat pump water heaters (HPWH).
Also has anyone used R600 as a replacement? I'm asking this because with R22 the head preasures for, say 60ºC would blow the compressor, however R600 uses about 15bars only at that preasure.
Thanks

Re: Heat Pump
R22 AT 60°C has pressure of 23,5 bar which is perfectly safe for any hermetic compressor. 27 Bar is usual limit.
