Communal heating that delivers

Debris in the primary circuits of communal- and district-heating systems can lead to users not receiving enough heat and hot water. Helen Gibbons of Giacomini goes behind the scenes to explain why.

Smart meters cut costs for Sheffield customers

Switch2 Energy, which specialises in smart metering for community heating has won the Association for Decentralised Energy’s customer-engagement award for its smart-metering partnership with Sheffield City Council. The company’s smart-metering technology is helping to dramatically cut customer bills across over 6000 homes connected to the districting heat network.

Edinburgh University installs trigeneration energy centre

A new energy centre for the heating, cooling and electricity networks of the University of Edinburgh’s Easter Bush Veterinary Campus will incorporate trigeneration. This £9 million project by Vital Energi will include a 1.5 MW(e) CHP engine and a 600 kW absorption chiller. There are also two 4 MW boilers and a 1.5 MW vapour-compression chiller. The heating and cooling systems will both have a 100 m3 thermal store.
