ABOUT YOUR WATER HEATER 

17 

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, the solar collectors, components and fittings. Refer to 

“Water Supplies”

 

on page 20. 
 
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

 20 

to

 22. 

 

HOW LONG WILL THE WATER HEATER LAST? 

The water heater is supported by a manufacturer’s warranty 

(refer to page 

4

)

. 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”
