Heating system

The energy performance of a heating system is influenced by a number of factors. The main ones typically include the type of fuel used and the seasonal efficiency of the heating equipment. Refer to the Fuel Fired Heating System Schematic for more information.

Software & Data
The RETScreen Software Heating System Model can be used worldwide to evaluate the energy use and savings, costs, emission reductions, financial viability and risk for heating system energy efficiency measures. The software can model a wide variety of projects in residential, commercial and institutional buildings and industrial facilities ranging from fuel switching, to improving the seasonal efficiency of the heating equipment. The software (available in multiple languages) also includes product, project and climate databases, and a detailed user manual.

Note that for a detailed analysis of heating systems, the user should refer to the Heating / Cooling section to learn more about the comprehensive heating models available in RETScreen.
