Water with a high TDS concentration will greatly accelerate lime and scale formation in the hot water system. Most high TDS
concentrations precipitate out of the water when heated. This can generate a scale accumulation that will greatly reduce the service life
of a water heater.
The manufacturer of the water heater has no control over water quality, especially TDS levels in your system. Total dissolved solids in
excess of 2,000 ppm will accelerate lime and scale formation on the element or heat exchanger. Water heater failure due to total
dissolved solids in excess of 2,000 ppm is a non-warrantable condition. Failure of a water heater due to lime scale build up IS NOT
covered by the warranty.
Hardness: 7 grains
Chloride levels: 100 ppm
pH levels: 6-8
TDS: 2000 ppm
Sodium: 20 mGL
C. POTABLE WATER PIPING DETAIL
Figure 6 - This drawing is meant to demonstrate piping concept only.
D. SOLAR HEAT EXCHANGER PIPING
Set up the primary balance of the system components following the piping detail in Figure 6.
Run ½” type M or larger copper pipes, or flex line sets, to and from the collector following the direction of supports, penetrations, and
other relative items.
