Thank you for choosing Sunflower solar water heater. You now have a solar heater with the world’s best
technology. It has superb performance, is safe and reliable.
To get the greatest benefit from your Sunflower solar water heater, please carefully read the User’s Manual
all the way through before installing and using your solar water heater. Then proceed with your installation
and use it according to this manual. Please do not discard your User’s Manual. Keep it for later reference.
(Note: This manual is exclusively for the Sunflower heat pipe vacuum tube (5818) pressured series solar
water heater.)
1.
Features
1). Low heat loss:
The Sunflower solar water heater has excellent heat insulation using imported, high density, high strength
polyurethane foam which is foamed in place under high pressure.
2). Low heat diffusion
Heat diffusion at all connections is greatly reduced, virtually eliminating heat losses by convection or
conduction, resulting in high heating efficacy.
3). Connections and Valves
●
Connections to the water inlet, outlet, sensor and magnesium rod are all underneath the water tank for
easy access. For greater safety, the electrical heater inlet is on the left side to avoid dry burning if not covered
by water.
●
Uses a small elbow pipe in the water inlet. By doing this, the cold water will not mix with the hot water so
quickly, and the cold water will not flow to the hot water outlet.
●
Uses a P/T valve, Air suction valve and Single direction valve to protect the solar heating system.
These
valves come with the system. Not all suppliers offer these valves. Refer to Fig 4.2 below.
Note:
The P/T valve needs to be connected with a pipe and make the pipe outlet face to the ground, if the valve
were to open, the pipe directs the water to the ground, not straight out where it might hit someone standing
nearby, causing harm and scalding.
4). Easy functional extension:
This solar water heater is fitted with a water feed-in connection, overflow connection, connections to
level/temperature controls and an electrical element. The user can have a number of options depending on
his actual needs.
●
Uses a standard plug for the Connections of sensor and electrical element
●
The Sensor is an accessory to the level/temperature control which is sold together with the level controller,
electrical element and water feed-in valve as accessories.
5). The Solar water heater continues to work even if a heat pipe is broken
Because each heat pipe works independently, and is inserted into a water tight fitting on the tank, should one
or more tubes become broken, the Sunflower solar water heater continues to operate at a somewhat reduced
efficiency until the broken heat pipe(s) can be replaced.
