A little more clearing, Sky:
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.
