Failure of water heaters at hotel

Saunton Sands Hotel had reported regular failures of its water heaters through corrosion brought through its use of ‘soft’ water off Exmoor. Often the water carried with it vegetative debris which collected in the water heaters that then stained the water supply with a brownish deposit which was evident in the rooms. The water heaters lasted for about 2 to 3 years and their efficiency declined as the debris increased which also coated the internal surfaces in the heaters.

Non-chemical solution

KorrosionGUARD the non-chemical solution was to use a physical cathodic corrosion protection device which was fitted onto the ‘make-up’ water line to the water heaters. This stopped all the steel of the water heaters being attacked by the soft water. The water heaters now work as they should with life increased to their commercial expectancy and the water colour effect has been removed, leaving the hotel with a clean usable supply for its occupants. Water heater asset protection achieved, energy efficiency was ensured and the hotel took a notable step to reducing its ‘carbon footprint’ as a consequence of this action.
