Commercial project

Mulberry Bush School

School heating and hot-water plant replacement

Our work

The existing plant

The school’s plant room housed Broag Remeha L200 boilers dating from 1998.

The replacement

The replacement specification called for two Firebird Envirogreen commercial oil boilers, a 200kW plate heat exchanger to separate the boiler circuit from the existing heating system, and a 300-litre indirect hot-water cylinder.

Designed around the school

The scope also included variable-speed circulation pumps, insulated and labelled pipework, and integration with the school’s existing building-management controls. The photographs show the old plant, strip-out, replacement boilers and cylinder, pumps and insulated services.
