New boilers for old at Dunsville Primary School

Staff and pupils at Dunsville Primary School in Doncaster are benefitting from highly efficient heating and hot water, thanks to four 120kW Thision L Evo gas condensing boilers from Elco. The new wall mounted boilers have been installed in-line on a floorstanding cascade system within the school’s basement plant room.

The new Thision L Evo boilers have replaced two ageing and inefficient coal-fired units, which have been in operation for decades (see before and after images).

It is estimated that the old boilers were running at less than 50% efficiency. The gascondensing Thision L Evo boilers from Elco are over 97% efficient. Furthermore, the new boilers significantly reduce harmful emissions, with NOx levels now less than 40mg/kWh, which already meets future class 6 regulations.

Mechanical and electrical contractors for the project were Essington-based Staffordshire Mechanical Solutions. Commenting on the project, Project Manager, Dave Seward, said: “It’s not often that we come across such old equipment, especially systems that are still running on coal.

“Overall, we’ve been pleased with the installation and the after service from the Elco team, especially our sales rep Brett Stokes, who always ensures our projects receive the best attention from start to finish.”

As part of the boiler upgrade, the Thision L Evo units have been installed with a combined flue system, as well as upgraded pumps and new BMS.

Thision L Evo boilers utilise the finest technological features and components, offering customers a highly flexible unit that can be specified for an extensive range of applications.

Outstanding features include: a flat metal fibre cold flame burner for extremely low NOx emissions; a robust stainless steel heat exchanger with double wall geometry providing superb heat transfer; extensive cascade arrangements for powerful and flexible systems; plus the latest control functionality to ensure optimum performance.
