Maximum claimed efficiency
only for 300 days |
Approximately
350 days, because
of innovative design. Hotwater assured
even on clear winter days. |
|
effect of hard water
|
Life of system and efficiency
drastically gets reduced over a period of time as scaling sets in and chokesthe
metallic absorber pipes (small dia of 12.5 mm) and also leaks develop which
require costly periodic cleaning and maintenance.
Tank cleaning manually impossible because of completely
sealed design. |
Non
metallic glass pipes with widest
absorber diameter (37mm) prevent choking
and blocking of water flow and ensures maximum efficiency and life of system.
Glass absorber pipes can
manually cleaned very easily.
Design provides for easy
cleaning of tank, manually. |
|
START-UP AND heating time
|
Delayed heating process from
cold to hot - takes upto 5 hours. |
Low start
up time from cold to hot in just 2
to 3 hours. |
|
suntracking feature
|
Design does not provide for
it. Maximum input only at 12:00 noon |
Full
360oC usage of absorber area enables
94% suntracking efficiency allowing
maximum solar radiation input throughout the day. |
|
effect of external weather
and ambient temperature
|
Design dependent on ambient
temperature, hence low efficiency during cold weather. |
Independent
of ambient temperature - Ideal even
during winter weather conditions. |
|
Internal connections between
collector and storage tank
|
Use of interconnection pipes
results in heat loss and reduces life of system |
Integrated
design, completely eliminating inter-connectivity. |
|
Number of fins and tubes
per collector in a 100lpd system
|
8 or 9 |
12 or
15 |
|
Tank material and welding
|
Outer tank is generallyof aluminium,
only inside is of stainless steel, are welded |
Both
inner and outer tanks are of stainless
steel. Inner tank is TIG welded. |
|
tank insulation
|
Glass wool / rock wool etc.
Possibility of insulation getting soaked during
rain, reducing the heat of stored water. Insulation material requires frequent
replacements. |
Highly
efficient PUF
for very high retention of heat overnight.
PUF material
does not absorb water. Absolutely no deterioration of PUF
material. |
|
location of system
|
Limitation to roof mounting
resulting is very great loss of heat due to lengthy plumbing pipelines
from roof to bathrooms. |
Balcony
type innovative mounting design helps
even multistoreyed houses
and apartments
dwellers to get the benefits directly
since no need for lengthy plumbing pipes |
|
length of the system
|
Long Base Length of 10 feet |
Short
base length - only 6 feet. |
|
Overhead cold water tank
height to base of the system
|
Requires the overhead cold
water storage tank to be mounted atleast at 6 to 7 feet |
Very
low height of just 4 feet. |
