ThermoPower-VTS30HP is a solar thermal hot water heater system which pre-heats
city water with solar energy prior to feeding to the conventional hot water heater. It
can be integrated with the existing gas, electricity, propane or oil hot water heater by
installing at the upstream of the existing hot water heater. Food grade materials should
be used for all water contact areas.
A mixing valve must be installed if the homeowner does not have one currently. Set
the output water temperature at a point of 48.9
o
C (120
o
F).
The tank upper temperature limit is 300
o
F and 130 psig. As the thermosiphon system
has no way to stop the operation of the solar collector, always install a TP-R valve to
release some high temperature water out of the tank then mains water will charge the
tank to keep the tank within normal conditions.
The T&P valve releases some water out of the tank when the temperature is more than
194°F, or the water pressure is above 58 PSI to ensure the safety of the system.
And the specification of the TP-R is:
Inlet:1/2 in tapered male thread
Outlet:1/2 in parallel female thread
Maximum opening temperature:90
℃
/99
℃
Rated working pressure: 0.4MPa/0.6MPa
Maximum working pressure
：
1.5MPa
If you have a long time to go out of your home, and the system will not be used
during that period, we recommend you drain down the system and close the inlet
valve to avoid overheating. And in order to prolong the system use life, you had better
to cover the collector using a canvas clothes a mat.
