My current tankless, instantaneous gas water heater is placed in a location where pipes in and out of it are 3/4''.
I was planning to remove it and install an electrical, tanked water heater, in a different location, where a shower used to be. When starting the work, I actually realized that the pipes there were 1/2 ''.
Is that likely an issue in terms of having enough hot water at the other end of the house for showers? The distance between this electrical water heater and the furthest shower would be about 15 meters (49 feet).
