When the tank gets too hot, please drain down some hot water and then charge the
mains water to cool down the system slowly.
All exposed areas need to be well insulated to resist freezing. The insulated tank keeps
the hot water in the tank from losing too much energy throughout the night. The system
can absorb energy at most weather conditions, even on full cloudy days in winter. The
collector tubes still get energy from infrared heat passing through the clouds on fully
cloudy day.
All labeled valves (V1 to V5) must be installed within an adult’s reach. Draining valves
(V4 & V5) must come with hose bibs that can connect a garden hose for draining
purpose.
Piping should be sloped toward drain ports with a drainage slope of no less than 2 cm
vertical drop for each meter of horizontal length (1/4 inch per foot).
The illustration below is the installation pipe line of pressurized solar water heater.
The directions of each valve and the corresponding positions should match the
illustration. There should be no leakage in the tie-in. The pipe line must have heat
preservation and anti-freezing.
Underground piping subject to vehicular traffic shall be installed to withstand the
additional load applied by this traffic. The trenches and backfill shall be free of sharp
objects in contact with the pipe.
As the system is a solar-only system, there will be some days during which it cannot
meet the user’s heat demand if the solar irradiance is not optimal. It requires auxiliary
hot water heating equipment to ensure that user demand can always be met.
Our system can plumb with electrical, gas, or oil water heater; for connecting detail,
please reference the below diagram. Please note that, when you choose the backup
water heater,
“THE AUXILIARY WATER HEATER MUST HAVE ADEQUATE CAPACITY,
LISTED AND LABELED BY AN ACCREDITED LISTING ORGANIZATION.”
The backup water heater thermostat set point can be 51.7°C (125°F) to meet the final
