The iStore and iHeat tanks are made in China to our specification, these tanks have been used by us for 18 years in across the country. With 40,000 tanks now installed over this time we have very high confidence level in the performance and longevity of the tanks. Some states have some quite harsh water and others high pressures. Note that all installations require pressure reduction valves to comply with the Australia wide 500kpa limitation for household plumbing fittings which also protects the tank. The iStore tanks have 2 sacrificial anodes, one whole of life and the other a service anode that should be serviced approximately every 3 years depending on your water quality.
