ABOUT YOUR WATER HEATER 

11 

DOES THE WATER CHEMISTRY AFFECT THE WATER HEATER? 

The  water  heater  is  suitable  for  most  public  water  supplies,  however  some 
water  chemistries  may  have  detrimental  effects  on  the  water  heater,  its 
components and fittings. Refer to 

“Water Supplies”

 on page 15. 

 
If  you  are  in  a  known  harsh  water  area  or  you  are  not  sure  of  your  water 
chemistry,  have  your  water  checked  against  the  conditions 

described  on 

pages

 15 

to

 18. 

 

HOW LONG WILL THE WATER HEATER LAST? 

The water heater is supported by a manufacturer‟s warranty 

(refer to page 

46

)

There  are  a  number  of  factors  that  will  affect  the  length  of  service  the  water 
heater will provide. These include but are not limited to the water chemistry, the 
water  pressure,  the  water  temperature  (inlet  and  outlet)  and  the  water  usage 
pattern. Refer to 

“Precautions”
