How are savings estimated?

  To calculate savings we start by looking at past fuel bills. Three years is ideal, however it can be done with less. The fuel bills are analyzed to take into account variables that have a noticeable impact on fuel consumption. Some examples would be:

• Outside temperature - Degree days are the standard by which gas and oil companies measure the amount of coldness. These statistics are readily available from the gas and oil companies and are utilized to determine the amount of fuel consumed per degree day so that accurate comparisons can be made from month to month and year to year.
  
  
• Occupancy - In hotels, for example, occupancy has a big impact on hot water heating requirements in particular.
  
  
• Production - In manufacturing and processing settings, fuel consumption is often tied directly to production.

  Using past fuel consumption records and applying the appropriate variables, a simple model is developed that creates base line fuel consumption. This base line is used to calculate subsequent fuel savings. The calculation is based on fuel consumption savings only, not on cost savings. Given the trend of increasing fuel prices, a 20% savings in fuel consumption could quickly turn into a 30% to 50% cost savings as prices rise.

  How are Fuel Savings Estimated Prior to Installation of the system.

  Fuel savings can be estimated in advance through an examination of past fuel bills combined with the initial inspection and testing of the equipment. Specialized equipment is utilized to take readings on the temperature and composition of the flue gas and to estimate the amount of excess air and oxygen. With all of the data at hand a reasonably accurate estimate can then be made of the fuel savings that would be made with the installation of the Stanlin Energy System.

Is the estimate going to be exact?

  No it won't be. But based on past product performance and the science surrounding the reduction of excess air and oxygen levels we are generally pretty close on our estimates and if anything tend to be a bit conservative. So there's a good chance you will save even more.
