Case Study
Sheraton Heathrow Hotel
Scale management and water quality optimisation for a major London hospitality venue
Industry: Hospitality
Location: London, UK
Status: Completed and operational
The challenge
The Sheraton Heathrow Hotel had long struggled with limescale build-up and declining performance from ageing ion-exchange softeners. Scale was affecting hot water systems, pipework, outlets and kitchen areas, raising concerns around energy efficiency, equipment lifespan and water hygiene management — all while maintaining hospitality-grade soft water in key areas remained a priority.
The solution
Sidon Water delivered a combined water-treatment solution tailored to the hotel’s needs:
- Duplex ion-exchange softening – correctly sized to current demand, retaining existing bulk salt storage and automated refill systems for reliable soft water in guest and kitchen areas.
- Integro™ electro-chemical conditioning – installed to address historic limescale and provide continuous protection during softener service intervals or temporary performance reductions.
This dual approach provides both effective mineral removal and active scale control – improving resilience and system performance across the site.
The outcome
Since commissioning, Sheraton Heathrow has seen:
- Noticeable reductions in system scale
- Consistent softening performance
- Lower maintenance burden on plant and outlets
- Improved confidence in water quality and hygiene
- Greater operational resilience
Summary
By pairing correctly specified softening with active conditioning technology, Sheraton Heathrow has secured a high-performance, low-maintenance water treatment solution that supports operational efficiency and long-term asset protection in a demanding hospitality environment.
