4-4.1 Notes on Heating System

1. The total output from the Electrastream for hot water and heating is 9 kW @ 240V

(30,000 Btu). The radiators should be sized to suit.

2. The schematic system shows a kick space fan assisted heater, these are efficient

space saving units, ideal for small dwellings.

4-4.2 Pressure Gauge

The pressure gauge is provided to indicate the heating system pressure.

When the system is full with cold water and all radiators are full, on and bled/vented, the

gauge will show the cold fill pressure.

Set the red pointer to the cold fill pressure. If the system pressure, indicated by the black

pointer, falls below the cold fill pressure, it means that the system requires topping up.

4-4.3 Pump

Electrastream is supplied with a standard 3 speed central heating circulating pump and

isolating valves. This should be fitted in the flow from the indirect cylinder before the

bypass valve.

Normally the pump will be set at speed 2 (II).

The pump is wired so that it is ON when the heating control system is set for heating ON

and the room thermostat is set higher than the ambient temperature - see wiring diagrams

figs. 3-3a and 3-3b.

4-4.4 Heating PRV

The pressure relief valve (PRV) is provided to vent excess pressure from the system. The

valve will open when the pressure exceeds 3 Bar ± 10%.

The valve can be manually opened by turning the red knob clockwise, to close the valve

continue turning clockwise until it clicks.
