Gas Furnace Consumption Ramping Up

Applying a little strategy, this data can be used to optimize the idle warm temperature of the furnace.  Simply lower the idle temperature by 25 degrees with each successive production run noting how much gas is used to return the production operating temperature.  Compare this with amount of gas used to maintain the lower idle temperature between production runs.   Determine optimum idle temperature(s) based on the minimum amount of gas used.

The optimum temperature will most likely vary with the length time between runs. Determine the difference in the before and after amount of gas used and multiply by the number production runs to determine savings over time.
