• Uni Used Head When Heating Hit Hiccups

The University of St Andrews been forced to procure and  interim heating and hot water system during the shutdown of its existing heating infrastructure for a major upgrade.

The University is an old bird - founded in 1413. Its historic buildings were heated by an ageing heating infrastructure and it became necessary to shut down the campus’ heating and hot water system to install new boilers and replace sections of pipework.

Aggreko to designed and implemented a temporary solution with three separate bespoke heating packages totalling 2000 kW to different areas of the campus. Four 250 kW boilers were placed at a distance of 75 metres from the existing boiler room and hoses were run to provide heating and hot water to the United Colleges and Irvine building. This ensured that lectures and other day-to-day activities could continue as normal.

Two additional 250 kW boilers were situated 50 metres from a second boiler room at the Arts Building, while two others were installed in an extremely limited space at the Psychology Building, which houses critical facilities that require consistent temperature.

A very compact solution was needed to make effective use of limited space.

Robert Watson, Electrical Engineer at of St Andrews, said: “Once the heating survey was completed, it was apparent that we needed to implement immediate maintenance and upgrades.  We spoke to Aggreko first as we knew they could respond quickly and had confidence that they could design and provide a full, reliable interim heating scheme."

Aggreko used its new high efficiency 250 kW boiler model that can provide temperatures up to 90ºC and pressures up to 10 .  The new technology combines an advanced dual stage burner, three-way valve system and smart controls to optimise temperature control and minimise fuel burn and emissions.

Picture: The boilers are housed in a compact canopy case, which makes them easy to transport, and permits use in confined compounds, service yards and boiler rooms.
