I'm building and now in sheetrock phase. I have a long DEDICATED run from HWT (not tankless) to far bathroom (approx. 75' of 3/4 inch pex). My plan was to not have a dedicated recirculating line and install a Metlund D'mand pump or similar type pump with the diverter valve to dump into the cold side. I'm not sure of how I will like luke warm water in the cold line though. Maybe you guys could comment on this? I'm also here to ask about the possibly another alternative to this.
FYI This bathroom will be used by 3 people and it has a tub/shower + toilet + two sinks.
I'm wondering about doing an electric 2.5 gal hot water tank (not tankless) under the sink instead of the demand pump. I already have a dedicated 110v under one sink. Obviously I'm not going to supply this entire bathroom with the 2.5 so I would use the hot line coming from main HWT as the supply for the 2.5. I calculate 1.5 gallons of cold water would be sitting in the 3/4" pex pipe. When the little 2.5 gal tank runs out will enough hot water have will have entered from the main HWT to keep from getting a cool water blast?
Thanks in advance for your advice!
