MHG provides efficient response to variable space-heating loads

Replacing aging cast-iron sectional boilers in a sheltered-housing scheme in Barnes has improved energy efficiency by making possible an efficient response to the variable heating loads during the day. The upgraded plant comprised three ProCon MC115 gas-fired condensing boilers from MHG heating.

Diana House is a purpose-built sheltered-housing scheme operated by Paragon Community Housing Group. It comprises 32 homes to rent, plus a manager’s flat.

The boilers were installed by Industraheat, whose Robin Scottow says, ‘In upgrading the boiler plant, we have used the ProCon MC115 boilers in a cascade configuration to ensure an efficient response to the variable heating loads throughout the day. In parallel, we have installed new controls and upgraded the building-management system.

‘A major challenge was the need to maintain domestic hot water throughout the project, which involved locating temporary plant at the front of the building and connected to the plant room at the rear by running flexible pipework and cabling through the false-ceiling voids.’

Each boiler has a modulating burner which, combined with the cascade arrangement, provides a very responsive system while maintaining optimum performance at all loads. The BMS rotates the lead boiler to maintain similar run times.
