That will completely depend on how much water there is.
To answer this question we would need to know the BTUs of the hot plate, the area of the hotplate's surface, the interconnecting area of the hotplates surface and the water container. The Heat capacity of water we can get from a reference book.
There are no BTUs in an office water-cooler. But you can calculate how many BTUs are removed by the cooler. One BTU or British Thermal Unit is the amount of heat energy required to raise the temperature of one pound of water one degree Fahrenheit. There for when you remove one BTU you are lowering one pound of water one degree Fahrenheit. So if you know how many pounds of water you have and the temperature of the water you start with and the temperature of the water comming out of the cooler you can calculate how many BTUs the cooling unit of the water cooler has removed. BTU=Temp1 - Temp 2 X LB water

4800 BTUs will 150 square feet.
100 BTU if it's Fahrenheit
A small room is about 5,000 BTUs. Most people don't have a room that would require more than 10,000 BTUs.
90,000 BTUs - the 090 is what tells you the BTUs of the unit.

A 100 pound propane tank has a capacity of 2,160,509 BTUs
