Project Summary

Kelda were invited to trial both Air-Powered and BubbleSpa® technologies in The Cavendish Hotel to demonstrate its water, energy and financial saving potential, without compromising guest experience.  

Process

Kelda’s Air-Powered™ Deluxe Shower Panel and BubbleSpa® shower were installed in selected rooms, and fitted with data loggers to measure water consumption for a period of 87 days. During this time data loggers were fitted to existing showers to provide a benchmark for savings.
