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
IMPORTANT
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.
