Through the design & installation of modern energy-efficient condensing boilers, replacing life-expired district heating, the school benefited from attractive energy efficiency savings.

​The site legacy

This extensive school complex, spread over multiple buildings, had inherited a district heating system from the site’s previous occupiers. The system had become life-expired with poor insulation, leaks, and long lengths of buried ducting causing considerable energy losses.
​
Asters were chosen to carry out replacement of the installation.

​The project

Our remit was to isolate and disconnect the incoming district heating pipework & install energy-efficient condensing boilers as the source of heating. In order to do this we had to extend an existing gas main to serve the new boilers and fit new insulation to the pipework.

Aster Maintenance had to design the boiler room layout & pipework, co-ordinate this with the new BMS panel that was also being fitted, and commission the system.

The work included replacement control valves to regulate the heating & hot water in the building. The existing pumps were replaced with energy-saving inverter-driven pumps, offering further economies in service.

​All this work had to be undertaken during a school holiday period, with the system available for service by the first day of the following term. Careful co-ordination of all the various trades involved in a project of this complex nature was required.
