Because the heater block is adjacent to the
throttle spindle, some heat is also transferred through the spindle to the
butterfly, to prevent a thick build up of ice on the butterfly, which with the
type of carb used, can be a cause of rough running and possible engine failure.
Because there is no significant heating of the intake air when hot coolant is
circulating through the carburetor heater blocks, there will be a negligible
loss of full engine power.
A suitable tap and additional tubing (so that the pipe work can be extended
to fit the tap in the cockpit) is available as an optional extra. A digital
temperature gauge is optional also, and this monitors the temp of one of
the heater blocks close to the carburetor throttle spindle.
Extensive testing of the system has been carried out during an English
winter, and it has been demonstrated that the system will prevent the formation
of ice, and will also clear an ice build-up if the optional tap is turned on
after the engine begins to run roughly due to ice formation. The system has not
been tested under all possible conditions that may prevail, therefore its
effectiveness cannot be guaranteed in all circumstances.
Aircraft equipped with this device should never be flown in circumstances
where a successful "no power" landing cannot be made in the event of engine
failure.
