Hot Water Gas vs. Electric   

 

 

 

 

 

 

 

 

The table below is a simple Hot Water heater calculator. To use it, simply insert what you know, like size and gas or electric rates, or how much hot water you think you use daily. Each time you press the TAB key the table is recalculated.

All the information is for most typical heaters, known efficiencies, what a typical family of 3 uses daily in hot water from national standards and local (NIPSCO) gas & electric price information.

 

If you have any questions please e-mail us or call anytime!
