Hot water in an aptartment complex where I am the service electrician is running out because they only put 30 gallon heaters in.
Their plumber told the owners to hook up the elements so they run at the same time for quicker recovery.
I know the wire and the 30 amp breaker are not enough to handle that load but the plumber that gave the original advice did not. This leads me to not trust anything he is saying.
Will running both elements simultaneously cause too much pressure and cause the pop off valve to blow sending water all over the apt?
