Q: I have a 40-gallon natural gas water heater that is 5 years old, located at one end of the house and the bathrooms are at the other end. We added a recirculation pump with timer that allows us to get hot water within 5 seconds vs. without, which used to take 60-plus seconds.
However, I have never been able to keep enough hot water going for my wife's showering. She normally runs the shower for 15 minutes and unless it is at the top of the hot setting, she complains that there is not enough hot water. When we have visitors, it gets even worse. Does this mean we need a bigger-capacity water heater? Are there other solutions besides more capacity?
