: We just finished building our new home. It's a two-story, 3,500 sq ft, 2 full baths & 1-half bath. We have two hot water heaters, 1-gas 50 gallon-upstairs, 1-electric 40 gallon-downstairs. The gas water heater is supposed to be the main one, it is supposedly set up so that hot water will "feed" from the electric hot water heater until the hot water from the gas hwh "catches up". But, downstairs in the master bath (of which the gas hwh is directly above this bathroom on the second floor), we have to let the water run for several minutes before we get the hot water. Can you offer any advice?
This is a confusing system to me. You may need a recirculation line from one of the heaters with a pump to give you instant hot water to this bath. The gas heater is the better of the 2. They both should have been gas if it were my house and installed in a paralell so you have 100 gals all the time. Dale's Plumbing Service LMP
