San Antonio Hotel: Heater Cleaning Cut 75% at 21 GPG

Home 9 Case Studies and Results 9 San Antonio Hotel: Heater Cleaning Cut 75% at 21 GPG
Key results
75% less heater cleaning
Low-flow alarms now rare
ROI under one year

Case Study from HydroFLOW USA

The Challenge

  • Hotel hot water flow fell away as scale restricted strainers, showerheads and aerators
  • Extremely hard water measured 357 ppm, or 21 GPG
  • Guests experienced low pressure and a lack of hot water
  • Low-flow alarms sounded weekly
  • Service problems resulted in room discounts and, in some cases, full refunds

Tankless water heater strainer blocked by scale before and clean after HydroFLOW at a San Antonio hotel

The Solution

Two HydroFLOW® i100 units were installed on the main water lines feeding the hotel‘s tankless water heaters at the beginning of 2022. Flow rates began improving drastically a month after installation. Weekly low-flow alarms became rare, previously clogged showerheads and aerators now hold minimal debris, and tankless heater cleaning is 75% less frequent without harsh chemicals.

Key Outcomes

R

Tankless water heater cleaning is 75% less frequent and much easier

R

Harsh chemicals are no longer required for heater cleaning

R

Weekly low-flow alarms are now very rarely heard

R

Estimated ROI was well under one year at the 12 month mark

Independent Verification

All results in this study were measured and verified by third-party facilities managers and technical staff.

Summary

Tankless heater cleaning is now 75% less frequent and much easier, and the estimated ROI at the 12 month mark was well under one year. Twenty-one grains per gallon is extreme, and tankless heaters are the least forgiving equipment to put on it. Refunded rooms are the cost that finally makes a hotel act, and this is the post for hotels on very hard municipal supply.
