Investments in cost-effective district energy/heat pump systems reduce economic leakage, as more dollars are retained in the economy, thereby increasing discretionary income within a city.

Discussing the definitions of boiler efficiencies and presenting field data demonstrating seasonal efficiency of individual building boilers.

Diagramming the advantages of district energy systems with large heat pumps. 

Fisonic Devices (FDs) are heat exchangers, pumps, and mixers with patented optimized internal geometry. The theory of Fisonic devices was developed by Professor Fisenko by addressing safety problems of the Russian nuclear submarines during the disruption of the air tightness of reactor cavity (Ref 1-2).
