15% energy saving in Marriot Harbour Suites Hotel in Dubai Marina

As part of an agreement with a major hotel chain, Grundfos had the opportunity to undertake an Energy Check survey on a hotel in the South of England. The results indicated that there were substantial savings to be made by replacing the existing pumps with new variable speed pumps options, which can adapt their performance to the actual demand.

The report showed energy savings up to 787,572.80 kWh per year were possible and an ROI of just 2 years. The client has been so pleased with the results that they has requested a similar check on numerous other sites.
