Tankless vs. Tank
HOW IT WORKS
If you grew up in a home with lots of people taking showers and running appliances, you’ve probably
experienced what it feels like when that big tank runs out of water. Not too fun, is it? So how can this
box, about the size of a suitcase, mounted to your wall keep your showers hot and your tubs full?
SUPER-HIGH-EFFICIENCY
TANKLESS
• Cold water enters inlet pipe only when hot
water is required
• Gas ignites heat exchangers, which heat
the water
• Heated water exits hot water outlet to travel
through pipes to where it is needed
• Heater will adjust flame output as needed to
ensure a temperature set point is maintained
• When no more hot water is required, system
shuts off until hot water is needed again
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
• In the event
of tank failure,
large amounts of
stored water can
cause extensive
damage to the
home
A closer
look at the
comparison
Seriously. When you consider the space savings,
eco-efficiency and endless supply of hot water
that come with tankless technology, there is
no comparison. But when you look at the cost
savings over the long run, well, it just keeps
getting better. More comfort for less money?
Talk about a no-brainer.
