4.6.3 Water treatment
The heat exchanger is manufactured from aluminum alloys which will provide many years of excellent service, if
maintained properly. All heat exchangers require proper water conditions to remain efficient and function properly.
Failure to do so will lead to premature failures within the heat exchanger. The system should be filled with mains, cold
water (this will usually have a pH of between 7 and 8). Pressurized installations with a boiler/system content ratio of
1:10 or less should not require water treatment, provided the following conditions apply:
1.
The system is flushed thoroughly to remove all fluxes and debris and filled completely once.
2.
Make up water is limited to 5% per annum.
3.
The hardness of the water shall conform to the water quality document requirements (supplied with Boilers)
4.
All scale deposits will reduce the efficiency of the boiler and should be prevented. However provided the above
is complied with any scale produced will not be too detrimental to the boiler efficiency and will not reduce the
anticipated life expectancy of the boiler.
WARNING
The boiler water shall be maintained between 7 and 8 ph at all times. Failures to do so will nullify any and all warranties
implied
Suitable chemicals and their uses should be discussed with a specialist water treatment company before to carrying out
any work. The specifications of the system and the manufactures recommendations must be taken into account, along
with the age and condition of the entire system. New systems should be flushed thoroughly to remove any traces of
flux debris grease and metal swarfs generated during installation and assembly of a new system
For old systems to ensure any black metallic iron oxide sludge and their corrosives residues are removed, again by
power flushing, ensuring that the entire system is drained and completely clean of all possible debris
