depends on lots of issues........
whats the incoming water temperature? with incoming water at 40
degrees the rise amount must be high enough to get the water to a
comfy temerature.
few tankless can have enough BTU to raise incoming from 40 degrees to
say 120 or so
ANY OTHER water being drawn ? you can overwhem a tankless by drawing
too much hot water at the same time.
think filling a tub while someone is showering:( Burr cold hot water.
may be zero hot water in low flow applications like shaving, the
heater may not trip on
Besides all that theres the high cost of install, big gas lines. May
be issues with exhaust, chimney, may depend on power line to operate
no electric no hot shower, tankless are complex and may need heat
exchanger cleaning espically in hard water areas. so add cost for
trained pro service.
standard tanks are cheap, tend to work well dependably till they
leak.. and typically cost less than a decent candy bar a week when you
divide purchase price by life expectancy
