Tankless heaters are sized based on the gallons per minute (GPM) they are able to produce. Each tankless heater has a GPM rating associated with it. The best way to size a heater is to determine the maximum flow rate that you'll have at any time. You can assume that each shower requires 2.5 GPM.

Frequently Asked QuestionsQ. 'Why do I need to fill out an order acknowledgment form when purchasing one of these Eemax Three Phase tankless water heater?' The manufacturer requires us to include this form with our shipment request so that they will have verification ('proof') on-file that they manufactured and shipped the correct heater.

Special 3-phase heaters are manufactured-to-order and most residences are not wired for three phase configurations. Therefore, these special three phase are non returnable.
The manufacturer will not ship your water heater until this form is received.Q. 'What's the difference between the parallel turn on and the staged turn on?' The parallel turn on will give you a higher maximum flow rate, and it needs a higher flow rate to turn on than the staged turn on. The staged turn on will turn on with a lower flow rate, and it handles a lower maximum flow rate than the parallel turn on.Q. 'How does the staged turn on work?' Staged turn on models only use the heating modules needed to produce the desired output temperature.Q.

'Your products specify the 'temp. Rise' based on the GPM flow; what do you mean by this?' Temperature rise is the amount the heater raises the temperature of the incoming water, based on the flow rate shown of that water.
