Tankless Inline With Tank For High Output / Demand
I cant find much info on this. Has anyone installed a tankless that fed a 50 gal tank? I want to run a high output shower valve (moen io digital) where the capacity can reach 18 gpm. It will most likely not be run all the time at that capacity, but would like to have the ability to. I am also interested in only running the tankless when the demand is above 2 gpm. That way I limit how often the tankless kicks on, saving gas. I haven't found a tankless with that capability. Should I be looking for a volume specific diverter valve or maybe a control valve to switch the tankless on? Can the tankless lower limit be modified? If this is going to be too complicated, then what are my other options? I live in KY where the incoming water temp is an average 55 degrees. I also have a 1" gas feed, will I encounter any problems there?
