District energy is a rapidly expanding sector of the energy market and represents a basic means of saving energy.

The conversion from electrical to hot water space heating and DHW can be expected to reduce the energy cost for heating by more than 20% in most cases.

Construction of a district energy system has a ripple effect throughout the community, primarily in the form of lower energy costs.

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).
