Increase Water Quality &
Water-Heating Efficiency by
Preprocessing & Preheating
Water To Remove & Prevent Lime & Iron Deposits
Try the GFX/VWP system shown in Fig. 2 for 60-days to experience
the many unique benefits of both pre-conditioning and pre-heating city or well
water, especially in regions having hard water where VWP water processors can
restore heat exchanger efficiency by removing lime deposits.
The one shown in Fig. 2 was installed in the cold water line of a house
in Patchogue, NY on August of 2008. Within a few days, the strainer
installed to protect the tankless-electric water heater was clogged and its
magnetic flow-switch was jammed by rust & calcium from the 100-ft coil
of the first production G3-60 GFX that was installed in 1993. After
cleaning this recurring flow-switch problem was solved.

Increase Space-Heating
Efficiency by Removing & Preventing Lime Scale in
Radiant & Conventional Hot Water Heating Systems
After the VWP200 was operating for 2 months, the VWP100 shown Fig. 3
was installed in the hot water return line of the existing 12-year old Tankless Hydronic Heating
System, which has 30-year old, single-loop baseboard convectors with aluminum
fins on ½” Type-M copper tubing. Again, within a few days, the strainer clogged
& magnetic flow-switch jammed; this time by rust & calcium from the
100-ft coil of the 13-year old G3-60 needed to isolate heating &
potable water.
The VWP100 also eliminated this recurring flow-switch problem, then
sediment began accumulating in the auto-fill tank from 30-years of calcium &
rust deposits in the convectors. This improved both heating efficiency
& comfort.
