Parallel Installation
Parallel installation uses heaters that are identical in both BTU input and storage capacity. Normally, parallel installation is used when there is a demand for large quantities of hot water over a short period of time, such as filling a large garden tub or back to back showers. Equipment being equal, two or more heaters connected in parallel will deliver more hot water than the same heaters connected in series. In a parallel configuration, the hot water demand is taken equally from each unit. For every gallon of hot water drawn from each unit,.....see link
Series Installation
Series installation uses heaters that are not identical in both BTU input and storage capacity. An example might be when an expansion or addition is made in an application that will require additional hot water. For example, you add a new bathroom to your home. The existing system will not handle the demand and a new water heater must be installed. The new heater is not identical to the existing heater. In this example, series installation may be appropriate.............see link
I understand the difference, I have installed both systems residential and commercial settings
My question has to do with the "WHY" Of the Series installation being for tanks that are not identical in both BTU input and storage capacity
If 2 - elec. 40's are sitting next to each other, what would be the reason one should be a different BTU and size? Is the reasoning simply efficiency of savings of cost to operate?
looking for a logical debate,
