2 stage water source heat pump systems. Real savings or fluff
Totally excluding the cost of the system here, I would like to specifically ask about electric usage and efficiency of these systems in practice. I realize what the OEMS quote, 24-35 SEER ratings but I would really like to know if these are accurate and realizing that sometimes home efficiency is what it is.
Just FYI, I already have 4 wells and a 1acre pond so water source and disposal are not an issue.
Are these 2 stage systems typically operating with 2 compressors rather than a digitally controlled scroll?
Also, since it seems many systems are using an internal compressor and condenser coil, do these systems usually come precharged as a ready to use assembly or do they have to break down due to weight and size issues?
