One of the problems with appliances requiring “super-heated” water like water heater is it scales much faster compared to other appliances. Scale can shorten the lifespan of your water heater and reduce its overall effectiveness. However, A.O. Smith Pro AOW-AS20 Inline Descaler can help prevent the scale buildup to extend the life of your water heater and to not reduce its overall productivity and efficiency.
This filtration promotes the formation of inactive scale crystals that will flow through the system and stop them from sticking to the heat exchanger. Basically, the water will be filtered first in the inline descaler before it goes through the water heater since the filter is to be used with municipally treated cold water only. It cannot be used with hot water as well as water that is microbiologically unsafe or of unknown water quality without adequate disinfection before or after the system. AOW-AS20 filter can last up to 2 years before it needs to be replaced, depending on usage. It also effectively reduces cyst and chlorine taste and odor.
