I asked this question a week ago and got two answerrs both saying it was a precaution against freezing. This is nonsense, for if one compartment freezes both freeze. Water comes from a stand pipe or other source into the large compartment and flows into the smaller one through a cut in the separating wall. The smaller comartment has an overflow device of one sort or another. Both compartments can be completely drained by removing the plug at the base of the compartment.

If 1degC is 33.8Deg F
Then why isnt double of 1DegC ie 2Deg C double of 33.8Deg F.

This is the conversion:
1 C ...........33.8 F
2 C ...........35.6 F
But surely if double of one is two then double of 33.8 should be 67.6?
