Centralised efficiency

03 May, 2013

Installing heat-interface units in apartments as part of a community heating system rather than individual boilers opens up the potential for more efficient operation and the use of lower-carbon central plant. Neil Parry of Altecnic discusses how the technology enables consultants and engineers to deliver cost-effective and energy efficient centralised energy centres.

Refurbishment of the plant room at the 20-bed Molesey Hospital in Surrey has seen two Purewell Variheat 70 kW gas-fired boilers from Hamworthy Heating replace three gas-fired atmospheric boilers. Hot water is provided by two Dorchester DR-FC Evo30 direct-fired condensing water heaters. The project was one of more than 20 carried out by NHS Surrey to reduce carbon emissions and replace boilers and water heaters that were coming to the end of their economical life.
