Installation
Requirements
Unobstructed sunlight
on a flat or slopping
roof
Shadow-free area
Close to the bathrooms
to avoid long piping
& heat losses
A water tank at

Features
Superiorty
Of Vacuum Tube Collector
Technology
Vacuum
tube collector
Flat
Plate
collector
1.
Heat absorptions
from the infrared
rays of solar
radiation
instead of
the visible
light rays,
so during
winter and
cloudy days,
the system
absorbs infrared
rays as usual.
Heat
absorption
occurs from
the visible
light rays,
On cloudy
days performance
will be affected
significantly.
2. Heat
absorbing
surface
is always
perpendicular
to sunlight
because
of spherical
collectors
Heat
absorption
surface will
be perpendicular
to sunlight
only for a
short time.
3. Heating
continues
till late
evening
It
falls down
after 2 p.m
4.
It gives 10
o C higher
temperature
of hot water
in winter
& Cloudy
days.
It
is not possible
in FPC as
heating efficiency
falls significantly
on cloudy
and winter
days.
5.
The vacuum
inside the
collector
tubes vastly
reduces overnight
heat loss
Heat
loss will
be more at
night from
collector
panels.
6.
Salt or scale
formation
when using
hard water
will be reduced
Scale
formation
will be more
and may choke
the narrow
pipes within
the collector.
7.
Scale deposits
slide off
the smooth
glass walls
to accumulate
at the bottom
from where
they can be
easily removed.
Once
the scale
deposits are
formed it
stops the
flow of water;
the removal
of scale is
also some
what difficult.
8.
Installation
of the system
is very easy
Installation
of the system
is not easy
as VTC
9.
Area required
for installation
will be very
less
It
require more
area compared
to VTC
10.Incase
of damage
to the collector
tubes, individual
tube can be
replaced.
But
here entire
flat plate
has to be
replaced and
it involves
high cost
for replacement.
Energy
Savings
FAQ
1.Is
it very expensive?
When compared
to an electric
heater the Venus
solar heater may
sound slightly
expensive. But
a solar heater
will pay back
its investment
in 2-3 years,
through recurring
energy savings.You
may also be eligible
for rebates on
your electricity
bills in some
States.
2.What
could happen if
water supply is
irregular?
Incase cold water
supply is interrupted
during the day
, the heating
of water by the
solar system may
not be affected
significantly,
although hot water
cannot be drawn
for use till the
water supply is
restored.
3.Will I get power
and hot water
from this system?
No, Solar hot
water panels only
heat water. They
do not generate
electricity from
sunlight. As the
sun hits the glass
tubes in the panel,
water gets heated
and flows back
into the tank.
Solar electric
panels are made
of silicon and
convert sunlight
directly into
electricity. They
are different
from solar hot
water panels.
4.What
will happen on
cloudy days?
The VTC model
solar water heater
will continue
to function even
on cloudy days
due to heat absorption
from the infrared
rays of sunlight.
Efficiency would
be affected, however,
on rainy days.
5.Can I get hot
water during early
morning when sun
is not there?
Hot water produced
by the solar system
during the day
is stored in an
insulated storage
tank. The insulation
of the tank is
such that the
water remains
hot without significant
drop in temperature
for around 24
hrs. Thus water
heated during
the previous day
is available for
use the next morning.
6.What
are the Maintenance
requirements?
Venus VTC solar
water heating
systems do not
need significance
maintenance. The
collector tubes
may need annual
cleaning to remove
accumulated scale
and sediment deposits
at the bottom.
The system is
resistant to adverse
effects of weather
as it is made
of stainless steel.
7.Can
I use Hot water
from the solar
water heater in
the evening or
night?
Using the Hot
water in the evening
or night will
result in hot
water being unavailable
the next morning
as the system
will not heat
water overnight.
If you wish to
use hot water
in the evening
too, then choose
a larger capacity
of solar water
heater that meets
your needs.
8.What
is the expected
life of a solar
water heater?
Venus VTC solar
water heaters
can last for 15-20
years depending
upon the general
upkeep.
