Ask a Question
Can you have two showers going and a hot washer at the same time?
The max. flow at 70F temperature rise (differential between incoming cold water and outgoing hot water) would be 3.0 GPM. 70F differential is common for northern US climate. In the south, the differential would be lower and the GPM higher. To determine whether this model meets the demands, you would need to know flow rates of both showers and washer.
