Hard water causes serious and expensive damage that leaves behind calcium / mineral deposits referred to as scale. As scale builds, it gradually restricts water flow and decreases the efficiency of these various systems* (water filter, pipes, faucet, heater and etc)
Nothing reduces water heater efficiency more than hard water mineral scale. Accumulating on heating elements, it slowly reduces both heat transfer and water pressure, leading to lower performance, and it may cause premature failure. Preventing mineral scale formation with Descaling agent/Food Grade Citric Acid or White Vinegar ensures your water heater's optimal performance and service life.
If you already know the quality of your water. Installing a non-salt based water conditioner may prolong the life of your unit. We recommends DeScaling water filter to ensure consistent water flow, we recommend periodically checking for and removing any scale and dirt in the faucet aerators and showerheads, and in the filter screen in the unit (as shown below) Depending on water hardness, scale build-up may need to be flushed from the unit every six months to a year.
Shower water heater has a built in filter screen that should be cleaned from time to time to remove any blockage and sediments deposit.
In general it is recommended to use Descaling water Filter before connecting the inlet water flow through the system*, as it protects appliances including water heater against any damage caused by scale build up due to minerals found in hard water.
Recommended - Descaling Filter is to be installed on the cold water inlet of the water heater, where it treats the water entering the water heater. It will provide protection for flow rates up to 6 gallons per minute.
For Shower Water Heaters that already has mineral deposit or scale build up due to hard water or cases where descaling filters are not used. Descaling can be easily done by using Food Grade Citric Acid or White Vinegar (100ml) diluted in water (1 liter) passed through the inlet of Shower water heater to shower head.
