Tankless vs. Tank
STANDARD
TANK
• Large tank requires
more installation space
and management
• Water in tank is
heated and reheated
to maintain desired
set temperature
regardless of
usage or demand
• During times of
heavy use, water
can be depleted,
causing delays in
hot water supply
SUPERHIGHEFFICIENCY
TANKLESS
• Cold water enters inlet only when
hot water is required
• The flame ignites and heats two heat
exchangers, which heat the water
• Heated water exits outlet pipe to travel
through pipes to where it is needed
• Heater will adjust flame and water flow output
as needed to ensure a temperature set point
is maintained
• When no more hot water is required, system
shuts o until hot water is needed again
• Product lifespan of a tankless unit is twice
as long as that of a traditional tank**
Rinnai’s line of digital controllers
allows homeowners to set precise
water temperatures from multiple
locations in the home.
So how can a box about the size of a suitcase deliver an endless supply of hot water while a bulky tank can run out of hot
water when customers need it most?
