Castlegate Business Park

The following information has been provided by Robert Hitchens Group, a property developer and managed space provider following the installation of M2G.

"A significant reduction in oil consumption has been realised at Castlegate Business Park through the installation of M2G boiler load optimisers by Sabien Technology. Following recommendations from Kier Facilities Services, the M2G optimisers were fitted to both of the Estates 2.4MW oil fired boilers in Nov 09. During the following four month period Kier's Client, Robert Hitchins Ltd, realised a drop of 30% in oil consumption over the same period in the previous year, despite last winter being the coldest on recent record.

The M2G is an intelligent boiler load optimiser which improves the efficiency of each individual boiler regardless of age and size by removing “dry cycling”, an inherent problem found in existing and modern commercial boilers.

The unit was retro-fitted to each boiler and monitors the temperature of the water in the flow and return every 10 seconds, enabling the M2G to analyse the temperature losses from the boiler. The M2G calculates whether the temperature loss is caused by a genuine heating demand or from standing losses i.e. temperature losses through the boiler casing and flue. When the boiler tries to fire as a consequence of the standing losses the M2G will prevent the boiler from firing resulting in reduced energy consumption.
