HVAC SYSTEMS
Left: ‘Smart’ functions simultaneously supply Estates managers with detailed data, and keep plant running optimally – by identifying any issues before they risk causing disruption.
Applying the trusted ‘traffic light’ PPM system, all three pumps were labelled with a red light and deemed critical replacements. The traffic light system used was similarly applied to a variety of equipment detailed in the asset list, including the heating pumps, booster sets, and expansion vessels. As with any asset list, this was created to provide the Estates manager with further information and clarity around the ‘health’ of this particular plant room. In this case, the traffic light system proved extremely beneficial to those involved, allowing staff to prioritise what needed upgrading, when by, and the potential implications of a particular plant room breaking down. Wilo’s traffic light system ranks any equipment less than five years old as green, between 5 and 10 years’ old, amber, and anything over a decade old is ranked as red. Following the energy survey, Wilo
agreed with the hospital to install a new
hot water circulator pump, a variable temperature pump, and a constant temperature pump, within the specified plant room, having labelled all three original pumps as ‘red’. Replacing these pumps not only provides the assurance of reliability, but also means the hospital benefits from long-term carbon and cost savings due to the high-efficiency pumps offered by Wilo. The estimated time for complete return on investment in all the pumps will be around three years post- installation, proving that they are a viable, cost-effective solution to reducing the NHS’s carbon emissions. In addition to supplying and installing
the new pumps, Wilo also offers remote monitoring of the pumps and the plant room condition. This is undoubtedly beneficial to Estates managers that simply don’t have the time to consistently monitor the health of the many plant rooms they are responsible for, and simultaneously increases the likelihood of an issue being spotted before it worsens. The collective effort between the teams involved was crucial to the success of the pump installation at Sunderland Royal Hospital
Aiming for a safer, more efficient NHS Acknowledging the safety-critical nature of plant rooms and pumps in healthcare settings, a concerted effort from both ‘in-house’ Estates and Facilities personnel and external specialists is essential, as
