1. Features of pressurized solar water heater
• High food grade stainless steel 304 2B. State of-the-art welding and achieves potable
water status.
• Through the 365 degree inner tube absorber, reflectors behind the tubes, the heat up
time is very fast from the time the sun rises on the east side of the tube until it goes
down on the west side – unlike flat plate, which has a high output during the sun’s
highest energy, around midday.
• Utilization all year round, even in cold, windy climates where freezing does not
occur below -2 degrees Celsius for short periods of time.
• Can operate with incoming water pressures of 0.4 MPa – no circulating pump
or controller necessary.
• The system will still function if some vacuum tubes lose their vacuum or are
accidentally damaged.
• All day tracking capabilities due to 360 degree absorber on inner tube.
• The diffuser reflector plate behind the glass tubes adds to the heat gain during blue
sunlight days.
• When consisting of more than one unit, can be installed using parallel and/or
series connections, increasing the hot water capacity supply.

2. Structure of solar water heater
Component description:
HEAT PIPES: An evacuated-tube collector contains several individual glass tubes,
each containing an aluminum fin and a heat pipe. The heat pipe transfers the heat
efficiently to the water in the tank.
WATER TANK: The storage tank is made of three layers: inner shell, intermediate
foam insulation and outer cladding. The shell is built to hold water pressure maximum
of 150psi. Shell material is corrosion-proof food-grade stainless steel. Foam insulation
thickness is decided to maintain the tank water temperature self-sustainable during
continuous unclear days in the coldest wintertime. Outer cladding is normally
galvanized sheet metal, providing a fine surface finish and a long-lasting life.
EVACUATED TUBES: Top quality double-walled tubes are chosen. There is an
aluminum or copper coated mirror on the inside surface of the inner glass wall. The
mirror well traps the thermal energy inside the tube. On the metal mirror layer, there is
selective absorption coating, which converts over 99% energy of visible and invisible
lights.

JAMAICA
The outer glass wall acts as glazing, creating a vacuum space and protects the coating
against weather. On the inner surface of tube ends, a silver-colored getter material is
applied, which absorbs the remaining gases inside the tube hollow space. Deducting
the absorption and surface reflection of the outer wall of a tube, the overall efficiency
of a tube is over 92%.
REFLECTOR: Reflector is silver coated reflecting panel. The reflectors can improve
solar system thermal efficiency and reinforce the frame structure.
FRAMES: Frame is made of rustproof material. A frame may have full-length rear
legs, suitable for flat surface installation, or, shortened rear legs, suitable for sloped
surface installation. Length of rear legs could be cut to fit at site.
3. Working principle
3.1. Principle of vacuum tube
The vacuum tube is composed of inner tube, outer tube, selective absorption layer,
vacuum space, inspiratory layer. The outer wall of the inner tube is the selective
absorption layer. The space between outer tube and inner tube is the vacuum space.
At the bottom of the outer tube, there is an inspiratory layer which can be used to
absorb the remnant air.

3.2. Working principle of solar water heater
The vacuum tubes absorb the solar energy, and aluminum fin pass the heat energy
to the heat pipe. The liquid medium in the heat pipe is heated by the heat energy, and
then turns into the gas medium. The gas medium flows up to the top of the heat pipe
and transfer the energy to the cold water in the tank, at the same time the gas medium
turns into the liquid one and flows down. The liquid medium keeps recycling and the
water in the tank will become hot.

4.2 System Tolerance Information
Freeze tolerance limits are based upon an assumed set of environmental conditions.
Extended periods of cold weather, including ambient air temperatures above the
specified limit, may cause freezing in exposed parts of the system. It is the owner’s
responsibility to protect the system in accordance with the Supplier’s instructions if
the air temperature is anticipated to approach the specified freeze tolerance limit.
4.3 System start-up procedures
After the system installation, check there is no leakage in the system and follows the
following steps to start up the system.
Step 1: Connect Garden Pipe to Drain Valve V4, and keep V4 Open.
Step 2: Open the following valves: V0, V2, V4 and shut off the following valves: V1,
V3, and V5
Step 3: Keep the water running for 5 minutes to flash out the solder or stains after the
water from V4 is observed.
Step 4: Shut off V4 and Open V3, and the system is in normal operating status.

4.4 System pipe anti-freezing protections
This is a direct DHW system. The plumbing copper pipe needs anti-freezing
protection when the lowest temperature is below 23 Fahrenheit or -5 Celsius in the
coldest climate. The detail anti-freezing protection is described as follows.
The tables SRCC uses to evaluate the freeze protection provided by pipe insulation
indicate that 1.5 inches of insulation on a 0.75 inch type L copper pipe will protect the
pipe down to about 14F. It would be ok for the whole system if the entire pipe was
insulated well under this temperature condition.
It would be better to drain down the whole system if the temperature is lower than
14oF to avoid the connecting pipe freezing. The connecting pipe can be protected
against freeze damage.
In case of black out or power outage occurs during the cold weather when the
temperature is lower than 14 Fahrenheit or -10 Celsius, a system drain out procedure
must be followed as follows, and the existing Aux water heater must have adequate
capacity, listed and labeled by an accredited listing organization to continue provide
adequate hot water.
Step 1: Shut off V2 and V3 Solar Isolation valves to Isolate Solar System.
Step 2: Open V1 to using Aux hot water heater system, and bypass the solar water
system. Ensure the V0 is open.
Step 3: Connect Garden Pipe to both Drain Valve V4 and V5.
Step 4: Put the both Garden Pipes in the house drain dock or sinks.
Step 5: Open both V4 and V5 drain valves, until no more water comes out of either
pipes.
Step 6: Shut off both V4 and V5 drain valves.
When the electricity power is back to normal, follow the system start-up procedures
to set up the system to normal operation.
