1-1.1 The Electrastream System
The Electrastream system by GAH (Heating Products) Ltd. has been developed as a cost
effective solution for domestic hot and cold water and electric central heating with water
filled radiators.
Electrastream is a 9kW - 30,000 Btu system suitable for flats, small dwellings, offices,
home offices and granny annexes.
1-1.2 Electrastream Options Available
Consult GAH (Heating Products) Ltd.
1-1.3 Basic Principles
ELECTRASTREAM
Water in the unvented cylinder is heated by the high powered titanium electric tri-core
heater. Hot water is drawn from the cylinder and mixed with cold water by a thermostatic
mixing valve; this ensures safer lower temperatures at the hot water outlets.
The hot water within the unvented indirect cylinder also heats the water for the heating
system via the indirect coil within the cylinder. The circulating pump for the heating
system is controlled by a thermostat and programmable timer with override so that heat
is available on demand, providing there is a supply of hot water.

The Electrastream Plus system is supplied with a cold water storage accumulator.
The accumulator has an internally controlled butyl diaphragm, incoming cold water is
stored within this diaphragm at mains pressure. The air space between the diaphragm
and the accumulator case is pressurised, this balances the supply and maintains
pressure to the unvented hot water cylinder and cold outlets. When hot and cold water
outlets are turned on, the stored water from the accumulator supplements water from the
incoming main, this results in consistent pressure and flow to all taps, showers and baths
even when outlets are used simultaneously. Pressure will be sustained for as long as the
accumulator is holding sufficient volume of water.
ELECTRASTREAM PLUS PRE-PIPED
Operationally the same as the Electrastream Plus but supplied pre-piped and assembled
onto a mounting frame, the cold storage accumulator is supplied separately.

1-4.1 Hot & Cold Water Supply
Refer to fig. 1-2a for Electrastream.
Refer to fig. 1-2b for Electrastream Twin Coil
The incoming mains water supply is connected to the combination valve which is
Note
All installations must comply with relevant
regulations - refer to section 4-1.
assembled to the unvented indirect hot water cylinder. The combination valve has an
integral check valve. A single check valve is supplied, this is only required to be fitted if
back syphonage is possible from any item fitted prior to the combination valve.
Provision should also be provided in the cold supply for:-
1. Heating system fill.
2. Drinking water.
3. Water softener (when applicable).
4. Outside tap (when applicable).
The combination valve limits the incoming pressure to 3.5 Bar, it has an integral nonreturn valve and pressure relief valve (PRV).
Supply to the hot outlets is taken from the cylinder and mixed with cold water by the
thermostatic mixing valve, this ensures that a safer lower temperature hot water is
available at outlets.
Note
The alternative heat source must be
configured correctly to be used with the
GAH Electrastream system.
Note
The final fill of the heating system should
include the correct percentage of suitable
scale/corrosion inhibitor.
Cold supply to all outlets is taken direct from the main supply. If the mains pressure is
high (over 3.5 Bar) a 3.5 Bar pressure reducing valve is recommended.
1-4.2 Twin Coil - Alternative Heat Source
Twin Coil Cylinders have two coils, the upper coil is connected to the Electrastream
heating system. The Electrastream high powered titanium electric tri-core heater is
positioned about halfway up the cylinder so that it is only used to heat the water in the
upper part of the cylinder.
The lower coil is heated by the chosen alternative heat source (e.g. solar), this will heat
the water in the whole cylinder when ‘energy’ is available resulting in optimum efficiency.
1-4.3 System Control
The Electrastream system is controlled by a purpose designed Electrastream Control
Unit, this controls the hot water and heating ON/OFF times together with the heating
pump and valve. The control also has a dedicated programme that ensures efficient use
of electricity by selecting how many of the three immersion heater elements are required
to meet the current demand for heating or hot water.
1-4.4 Heating System
The heating system is for water filled radiators on a standard ‘sealed system’. The water
for the heating is heated by being pumped through the indirect coil of the cylinder. A
room thermostat and the Electrastream Control Unit’s programmable timers control the
circulating pump and motorised valve.
12
1-4.5 Electric System
The unvented cylinder is heated by a 240V, 9kW (combined 3 x 3kW) titanium tri-core
heater. This is controlled by the cylinder temperature sensor and the Electrastream
Control Unit.
Electrastream is designed to make full use of economy tariff electricity supplies and the
wiring must be arranged to make full use of this.
GAH offer a range of quality Water
Softeners, for information contact
GAH (HEATING PRODUCTS) LTD.
Note
When a water softener is fitted, the takeoffs for heating system fill, drinking water
and outside tap (when applicable), must
be positioned before the water softener.
INTRODUCTION 1INTRODUCTION 1

INTRODUCTION 1INTRODUCTION 1
1-4.6 Output
The tri-core heater provides 9kW (30,000 Btu) for heating and hot water.
1-4.7 Scale Protection
IMPORTANT All installations should have a scale protection device fitted
and in areas known to have hard water, a water softening device is
strongly recommended. The cylinder is not guaranteed against damage
caused by scale. Higher water temperatures of 65°C and above can
cause excessive scale.
GAH recommend and promote the use of scale prevention devices and water softeners in
areas that are known to have hard water. Installed correctly they prolong the life of
equipment and help prevent limescale formation in the pipework. Water softeners
provide the advantages of soft water, as well as preventing scale build up on taps and
shower heads.
Water softeners and any mains fed system must be of adequate capacity and should be
installed with suitably sized hoses to prevent any possibility of flow reduction.
1-4.8 Frost Protection
When planning the installation location of both the accumulator and the unvented
cylinder, consideration must be given to the risk of frost and the use of frost protection.
The design of the accumulator gives it a degree of frost protection enabling it to be
located within the dwelling, loft space or garage without further protection.
The cylinder can also be installed within the dwelling or loft space without further
protection.
Cylinders or accumulators must have frost protection when they are installed where low
temperatures could be a potential problem. Cylinders can be protected by a frost
thermostat.
To comply with Building Regulations, all necessary pipework must be suitably lagged.

1-5 Tri-core Heater Operation
Note
Refer to 2-2.2 for display settings.
IMPORTANT
On twin coil cylinders the
Electrastream tri-core heater must
be fitted to the upper immersion
heater tapping.
1-4.9 Handling and Storage
The Electrastream system will be delivered fully wrapped and palleted.
Lift the package carefully using a safe and suitable lifting method.
Keep the packaging intact and store in a secure dry and weatherproof area prior to
installation.
The three elements of the tri-core heater are switched on and off by the Electrasteam
Control Unit. They have a staggered switch on sequence that prevents sudden high load
on the power supply.
The control unit also limits the use of the elements for efficiency.
When the hot water within the cylinder is within 2° of the set (8) Target 65°C, only one
element will be on.
When the hot water within the cylinder is between 2° and 4°C below the set (8) Target
65°C, then two elements will be on.
When the hot water within the cylinder is below 6°C of the set (8) Target 65°C, then all
three elements will be on.

Fig. 2-1a Schematic of Typical Controls
2-1.1 Isolating Switch
The system will have a double pole isolating switch with neon and mechanical indicators.
This could be a pull cord or wall mounted type.
When the switch is ON (neon on) the system is operational.
When the switch is OFF (neon off) no hot water or heating will be available.
It is advised to turn the switch off when hot water and heating are not required, i.e.
holidays etc.
2-1.2 Electrastream Tri-core Heater
WARNING Unlike immersion heaters, the Electrastream tri-core heater
does not have an internal thermostat, therefore the cover should not need
to be removed.
When the cover is removed live electrical terminals are exposed.
ISOLATE THE TRI-CORE HEATER BEFORE REMOVING ITS COVER.
2-1.3 Over Temperature Cut-Out Thermostat
In the Electrastream temperature sensor box on the cylinder is the over temperature cutout thermostat. This prevents the water within the cylinder from overheating.
The over temperature cut-out thermostat is a manual reset type, this means it has a small
button that pops up when the thermostat has been tripped by overheating.
To reset the system after overheating, switch heating and hot water OFF, allow time for
the water to cool, or run off some hot water, then remove the cap and press the button.

Testing the RCD will not cause loss of the
Electrastream Control Unit settings.
Display icons ‘Heat 1 , Heat 2 , and Heat 3 indicate that the elements are
heating.
If either of the Heat icons are displaying an exclamation mark
an element - see 2-2.3.
2-1.8 Residual Current Device (RCD)
The Electrastream system will be protected by a Residual Current Device, this will
automatically switch Off the electric supply if an earth fault develops.
The RCD must be tested at least every three months, this is done by pressing the RCD
‘Test’ or ‘T’ button, this should switch the supply Off. Reset RCD to On after test.
If the RCD appears not to be working correctly contact your installer or a qualified
electrician.
2-1.9 Alternative Heat Source Controls
For twin coil systems the alternative heat source will have its own controls - refer to
manufacturers instructions.
The alternative heat source would normally be a cost effective method of heating the
cylinder and should be used and controlled for optimum performance thus reducing
heating costs.
