How many people can shower at once?
A shopper on Feb 10, 2017
BEST ANSWER: The answer depends on the gallons per minute output on each shower head. If you referring to 1 shower, Model RTGH-84 will put it out 8.4 gpms, more than enough to handle 1 shower. Assuming that your shower heads have an avg output of 3 gpm, this unit can handle 2 showers comfortably at the same time. As long as your shower head does not exceed 4.2 gpm per shower, the RTGH-84 can handle at least 2 showers at one time. In order for this water heater to handle more than 2 at a time, your shower heads cannot put out more than 2.8 gpms
