Fig. 2-1c Thermal Cut-Out Thermostat
The heating and hot water system is all electric. The hot water for the taps (outlets) and
radiators is heated by the immersion heater in the cylinder.
The system will have the following controls.
Fig. 2-1a Schematic of Typical Controls
2-1.1 Isolating Switch
The system will have a double pole isolating switch with neon and mechanical indicators.
This could be a pull cord or wall mounted type.
When the switch is ON (neon on) the system is operational.
When the switch is OFF (neon off) no hot water or heating will be available.
It is advised to turn the switch off when hot water and heating are not required, i.e.
holidays etc.
2-1.2 Immersion Heater
WARNING The immersion heater does not have an internal thermostat
(like most immersion heaters) the cover should not be removed.
When the cover is removed live electrical terminals are exposed.
ISOLATE THE IMMERSION HEATER BEFORE REMOVING ITS COVER.
2-1.3 Thermal Cut-Out Thermostat
In the thermostat box on the cylinder is the thermal cut-out thermostat. This prevents the
water within the cylinder from overheating.
The immersion heater thermal cut-out thermostat is a manual reset type, this means it
has a small button that pops up when the thermostat has been tripped by overheating.
To reset the system after overheating, switch heating and hot water OFF, allow time for
the water to cool, or run off some hot water, then remove the cap and press the button.
If the immersion heater thermal cut-out trips more than once, switch off the Electrastream
isolating switch and contact your installer.
