Immersion Heater - TE75
A GLASS heater which goes inside your fermenting container and has a thermostatic controller
Homebrew immersion heater for stable fermenting temperatures. Adjustable thermostat for accurate control of your brew. Suitable for all sizes of fermenting vessel up to 25 litres, and can be used in glass or plastic containers.
Standard size rubber bung with airlock hole. 240 volts 100 watts.
The heater comes factory set to 24 deg C, and can be adjusted by the user from 14-34 deg C.
Before adjusting the factory setting, you should operate the heater for 4 hours to allow the temperature
of the liquid and immersion heater to stabilise.
Check the temperature of the liquid with a thermometer.
If it requires adjustment, switch off the power supply and allow the heater to cool for 20 minutes before removing it from the liquid.
This is very important, as the internal temperature of the heater can
be very high. Removing from the liquid too soon can shatter the glass.
The pointer on the adjustment knob is positioned so that when factory set at 24°c (75°F) it is pointing towards the cable entry point in the black rubber bung. Taking this setting as the 12 o’clock position, the knob should be turned clockwise to increase the temperature and anti-clockwise to decrease it.
Please note that only small adjustments are required, as the thermostat is very sensitive. It should be
moved to the 1 o’clock position first to increase the temperature for example and retested before
moving further.
Important: Do not turn the knob more than ½ a turn in either direction. Failure to observe this will cause permanent damage to the thermostat and invalidate the warranty
