Water quality
Rinnai cylinders are manufactured to suit most NZ council water supplies. However some supplies can have a detrimental effect on the cylinder, its operation and life expectancy. Stainless steel cylinders are not suitable for bore or tank water.
Water supplies with a high level of calcium carbonate (hard water) can cause scaling on hot surfaces. We recommend a temperature of no more than 65 °C to minimise scale buildup. Scale reducing or water softening devices should be considered in hard water areas. The unit is not guaranteed against damage due to scaling.
