Installing the Temperature Sensor
The temperature sensor should be installed in the sensor sleeve
nearest to the collector array flow. When the sensor is fully in the
pocket, using a tie wrap secure the cable of the sensor to the
insulation of the flow pipe. If the cable needs to be extended, use
a 2 core cable 1mm
2
.
To ensure optimal contact between the sensor and the
surrounding environment, the gap between the sensor
sleeve and the sensor element should be filled with a suitable
conducting compound. All materials used for installing
temperature sensors (sensors element, conducting compound,
cables, sealing and insulating materials) must be suitably
temperature resistant (up to 200˚C).

Solar Water Storage Cylinders
Firebird offer a range of solar twin coil unvented cylinders that have
been designed specifically for solar applications. A special open vented
triple coil cylinder is also available.
Unlike some other “dual coil” cylinders, Firebird solar cylinders have a
purpose designed solar heating coil at the base of the cylinder, which
ensures maximum heat input and efficiency from the solar energy, while
the back-up heating system (boiler) will heat the hot water via the upper
coil. The cylinder is fitted with bosses to accommodate solar sensor
pockets to enable correct heat control on the solar system.
The solar tank should be sized according to the size of the solar
collectors used – see section 3.0.
Some key features of the Firebird solar tank range are:
•
Premium stainless steel design for longer life and optimum
hygienic conditions.
•
Efficient thermal insulation. 60mm Polyurethane foam is
factory-injected between the cylinder and its outer skin.
•
Easy-clean white finish ensures professional appearance.
•
All connections marked for ease of installation.
•
Usual cylinder accessories supplied as standard such as
temperature and pressure relief valve, tundish,
expansion vessel, etc.
•
Immersion heater supplied with all cylinders.
•
Better resilience in hard acidic water.
