Energy Cost Calculator

The calculator estimates expenses for production of 1 kWh heat energy from boilers using different fuel types.  Typical input information for typical boilers is presented to facilitate initial estimations, if no relevant project information is available at this stage of the development.  These initial input data should be replaced with more specific project information upon its availability.
