1. Introducon
1.1 Thermann Solar Ready Tank
Thermann solar ready tanks (SRT) are an electric hot
water storage tank that contains seven (7) ports, four (4)
more than a standard electric hot water system.
This unique design advantage allows installaon of
an electric storage tank that can be easily, and cost
eecvely upgraded to solar at a later date. Perfect for
emergency break downs and maintenance.
When solar is added to the SRT under certain condions,
it may sll be eligible for government assistance/
incenve schemes.

2.1 SRT Port Connecons
IMPORTANT
Thermann solar ready tanks (SRT) must be installed
in accordance to AS/NZS 3500.4 as well as any other
relevant local/government standards.
All compression ngs must be of brass with copper
olives.
Teon tape must be used on all ngs.
2.1.1 SRT Port Sizes
Table 1. SRT Port Sizes
Port Locaon Size
Inlet (Mains) 20mm (3/4”) BSP
Solar Flow 20mm (3/4”) BSP
Solar Return 20mm (3/4”) BSP
Outlet 20mm (3/4”) BSP
Sensor Ports Adjustable Cable Gland
PTRV 20mm (3/4”) BSP
2.1.2 Pipe Work
For general mains pressure systems, the recommended
pipe size is 3/4”. All pipe work and insulaon must be
installed in accordance with AS/NZS 3500.4
IMPORTANT
When solar is added to the storage tank, pipe work
and insulaon can be exposed to much higher maxi-
mum temperatures. It is necessary that all valves and
ngs used are solar rated.

2.2 Pipe Work Connecons
2.2.1 Inlet (Mains)
The mains line should consist of the following brass
components when installing:
• Duo valve
• Expansion control valve
• Pressure liming valve
The ‘Quickie Kit’ can be purchased separately and
provides the above components with insulang jackets
to streamline the installaon process.
2.2.2 Solar Flow
When installing the SRT without a solar collector, this
port is simply plugged using the supplied 3/4” brass plug.
When installing SRT with a solar collector, this port is
used for the water line directed up to the solar collectors
to be heated, and consists of the following components:
• Solar collector
• Circulaon pump with unions
• Solar dierenal controller
• Check valve
• Flow meter
The Thermann retro-t kit provides the above
components to complete the plumbing of the solar ow
line.
2.2.3 Solar Return
When installing the SRT without a solar collector, this
port is simply plugged using the supplied 3/4” brass plug.
When installing SRT with a solar collector, this port
is used for the water line returning from the solar
collectors aer being heated. This line does not require
any addional components, but should be run as short
as possible and have connuous fall back to the solar
return port.
2.2.4 Outlet
The outlet is where the hot water from the SRT is
extracted to be supplied to the household. This line must
consist of the following component:
• Solar rated tempering valve
The Thermann pump staon kit is provided with the
above component to complete the plumbing of the
outlet line of the system.
2.2.5 Sensor Ports
When installing the SRT without a solar collector, the
sensor ports remain unused, as all heang is controlled
by the thermostat and element inside the electrical
co ver.
When installing the SRT with a solar collector, the
sensors must be coated with heat transfer paste inserted
through the cable gland into the appropriate port and
ghtened. For more informaon on sensors, refer to
manual supplied with controller.
2.2.6 PTRV Port
The PTRV port is where the SRT ‘pressure and
temperature relief valve’ is to be installed. All PTRV’s
must be ed with a copper drain pipe to carry any
discharge to an appropriate drain.
IMPORTANT
All SRT’s include a PTRV, which is located in the vercal
column of the SRT packaging.
PTRV handle must be operated every six months to
ensure valve sll works and is free from sediment and
clarion/lime deposits.
