MAINTENANCE

Effective maintenance must aim at preventing :-

a). a reduction in the influx of fresh water through the boiler

- this can result in the formation of sediment or limescale on the

boiler immersion heater elements

b). pockets of high temperature water across the boiler immersion heater

elements – resulting in their destruction by overheating

c). accumulation of sediment or limescale within the boiler, particularly on

or around the boiler immersion heater elements – overcoming these

developments by the introduction of small amounts of fresh, clean water

without any inhibitor or de-scaling agent
