Police force reduces gas use by 18.8% with Energys boiler-performance optimiser
The Energys approach to optimising the performance of boilers is achieving average annual savings in gas of 18.8% across 10 sites of the Avon & Somerset Constabulary. Savings range from 14 to 25% at each site, and the system can be accessed remotely to provide immediate and comprehensive visibility of gas consumption and savings.
Heating systems are designed to provide adequate heat at external temperatures down to -6°C. However, on an average winter day of 8 to 10°C a boiler firing cycle will typically range from 300 to 1000 s. The Energys approach is to extend he firing cycle and, in the process, reduce the percentage of burn time to utilise the large volume of hot water that exists in a commercial hot-water system to maintain temperatures. The efficiency of the system can be improved as the boiler will burn at its optimum efficiency for longer.
The Energys system is designed for floor-standing boilers of 50 to 2000 kW. Users will typically witness 50 to 100 fewer firings in a 24-hour period. The saving in gas, or oil, consumption are achieved by extending the cooling curve.
It typically takes around an hour to install one of these boiler optimisers.
