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.

1-1.3 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.

ELECTRASTREAM PRE-PIPED
Operationally the same as the Electrastream but supplied pre-piped and assembled onto
a mounting frame.
