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.

ELECTRASTREAM PRE-PIPED

Operationally the same as the Electrastream but supplied pre-piped and assembled onto

a mounting frame.
