The add-on HW on demand with the same 300 to 400 minimal similar savings is as low as 2300-2600 with a luxury 2nd tank but not necessarily of to have installed.
installing from tempmasters and tetcos and heat controllers and later wf cm and working solargy and flaht p I have found not hydro-delat hyd ht, but dual compressor and HW on demand in Cooling and Heating (cooling is 100% heat recovery to the HW, so loop and well circ is "OFF", then)
That Heat Reclaim becomes then a dissimilarity of a higher savings than just adding a w:w second piece.
DD: Well said . The air coils of about 6 to 7 years ago for MANY OEM, failed in all kinds of HT P and Hydro-Temp replaced them OUT of Warranty at the OEM cost, and when I repped (to 2011) dealers installed as low as under $100. ! Dual compressor allowed for programmed limitations of a first or just the 2nd compressor on the over-sized by as much as 3-tons water coils, getting higher than fixed w:w designed savings, too.
What did he just saw?
Please type out your response, if I can't understand it, then certainly a homeowner can't understand what jumbled mess you are trying to say. I can't even answer either of your posts since neither of them make any sense.
Where were you asked ?
Maybe Dean could work with your inquiry.
What did the POSTER end up with?
Does your OP mean original poster? I have to ask reading other notes by you.
Notes on "clearing confusion" that you well started to do , continue with the above attempt to more claerly show ALL the picture of the
PRIORITY ON-DEMAND 100% HW Full-sized internal heat exchanger, eliminating the need for other w:w pieces parts... (many times and in schools of the first NET-ZERO school in the United States, with HW-onDemand-GT).
is this too hard to read?
same 300 to 400 minimal similar savings is as low as 2300-2600 with a luxury 2nd tank vs
trying to convince all need 4000 dollars...?
just grab the sentence(s) and ask a Q, but more clearly for my understanding, too.
I have only sold ~ 73 GT; 163 franchises; 200+ construction projects; 247 financial planning services; and since 8 years old; and you still are not the first call for more clarity... it is harder than sizing a ground loop [which I have nailed repeatedly in temperature-performance guarantees in writing in three minutes or less]
ALWAYS ASK HOW YOU HEAT HW WITH A HEATPUMP ALL IN ONE SYSTEM by ONE UNIT-COMPRESSOR DOING TWO JOBS AT ONCE and at one electrical input, not more, in full condensing and selected heat mode desuperheating through the very same On-Demand HX coil.
Can we move on to the HVAC DHW and double prioritized Chilled/HW hx in a same single unit-SYSTEM that also goes to extended mimi-Like fancoils on insulated pex? - to show how savings over Mini's is another thread...
