Electrolytic water softener continues to perform 10 years on

Sentinel Commercial’s KalGuard electrolytic scale inhibitor is proving to be an effective long-term solution in tackling a loud banging noise that started to come from a of hot-water boiler when it was just five years old. The noise, known as kettling, is caused by an accumulation of limescale deposits on a heat exchanger. A KalGuard unit was installed in 2005, and its anode has been replaced only once — in 2010. The current anode still has 25% life.

Jim Dixon, house manager at Portsmouth Rugby Club where the unit was installed, says, ‘One day in 2005 we heard a terrific clattering noise, a kind of banging coming from one of the boilers. The whole thing was vibrating and, to be honest, it was pretty frightening. For all we knew, it was about to explode, so we took the decision to turn it off and call the boiler manufacturer.’

The club is in the Hilsea area of Portsmouth, where the water is extremely hard.

After the boiler had been repaired, the manufacturer recommended installing a KalGuard unit.

The unit has prevented the build-up of scale in the boilers and the rest of the system. For example, shower heads no longer scale up and require cleaning every two to three weeks.
