Step into the heart of heating efficiency transformation at Sligo University Hospital, located in the scenic northwest of Ireland. Just a few years ago, the hospital faced challenges with an outdated boiler and circulating pump system. The constant-speed pumps, delivering water at a medium temperature of 130°C, were proving unreliable, causing frequent breakdowns and maintenance headaches.
The extensive heating circuits at Sligo University Hospital, coupled with substantial pipe losses, led to inefficient delta T performance. The heating system, especially critical circuits linked to essential units, struggled to meet temperature requirements, particularly in colder weather. Recognizing the need for an upgrade, the hospital turned to Grundfos, a pioneer in intelligent pump technology.
Grundfos pumps are more than just pumps; they are intelligent solutions that auto-adapt to varying loads, ensuring an optimal match between the boiler load and heating system requirements. The hospital implemented Grundfos pumps, leveraging their ability to calculate and adjust to specific circuit loads. The intelligent Mi 301 remote from Grundfos became a vital tool, generating detailed reports, and providing real-time insights into pump performance.
The results are impressive, with Sligo University Hospital now achieving monthly electrical savings exceeding 70-80% on pump technology. The new pumps, equipped with BACnet communications cards, seamlessly integrate with the hospital's Building Management System (BMS), allowing for better control and monitoring. In contrast, the previous system lacked any form of communication, leaving the hospital in the dark about energy usage and heating system performance.
This transformative journey marks a significant stride toward energy efficiency, cost savings, and enhanced control for Sligo University Hospital. Grundfos has played a pivotal role in shaping a positive and sustainable future for heating operations within the hospital.
