Ashburn Clinic

Ashburn Clinic is a healthcare establishment providing psychiatric and addition services. The clinic halved its heating bill, saving just over $180,000 during its first year of operation with the new wood boiler. A 220kW ETA HACK boiler replaced lpg.
Description of facility: 

Since converting to LPG from coal many years ago, heating outgoings had risen dramatically. Following a detailed energy assessment by a consultant and detailed research by clinic management, Spark Energy was appointed to install a modern wood chip-fired ETA boiler and supply fuel-grade wood chips under a long-term contract.
