Important Health and Safety Information for Installers and Service Engineers

Health and Safety at Work Act 1974
Consumer Protection Act 1987
COSHH Regulations 1988
The following information is given as a requirement of the
above legislation.
Great care is taken by GAH (HEATING PRODUCTS) LIMITED
to ensure that Electrastream systems are designed and
manufactured to meet general safety requirements when
properly used and installed as recommended in this manual.
It is the responsibility of Users and Engineers to ensure that
adequate protective clothing and glasses are worn when
working with the Electrastream system.

SEALS AND INSULATION

SEALS AND INSULATION
Insulation and sealing materials are used in the construction
of the Electrastream cylinders. Units are sealed and when
used in the manner for which they are intended the insulating
and sealing materials do not present any known hazard.
However always observe the following recommendations:-
1. Avoid inhalation of fibres or dust, wear face mask.
2. Avoid eye contamination by fibres or dust - wear eye
protection.
3. As far as possible avoid any skin contact with Fibreglass
Insulation, Glass Rope, Mineral Wool, Insulation Pads and
Ceramic Fibre.

OTHER MATERIALS

SEALANTS, ADHESIVES AND PAINTS

Sealants, Adhesives and Paints are used in the construction of
the Electrastream components. When used in the manner for
which they are intended they do not present any known hazard.

ELECTRIC

ELECTRIC
The Cylinder Tri-Core Heater, Pump, Thermostats and Contactor
Box all have electrical supply of 230V (enough to endanger
life).
Always isolate before connection, adjustment, servicing and
repair.
When the Tri-Core Heater cover is removed high power live
electrical terminals are exposed.
ISOLATE THE TRI-CORE HEATER BEFORE REMOVING ITS
COVER.
Earth protection - Earth Continuity Conductors must be fitted
and must comply with IEE Wiring Regulations.

INTRODUCTION 1

Note
All installations must comply with relevant
regulations - refer to section 4-1.

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
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 non-
return 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.
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.

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.

Note
The final fill of the heating system should
include the correct percentage of suitable
scale/corrosion inhibitor.

The Electrastream System

Note
The alternative heat source must be
configured correctly to be used with the
GAH Electrastream system.
