The Zamboni machine uses a large auger with sharpened edges to scrape the ice, removing gross imperfections. Brushes then direct the ice shavings and any chips, up a chute to a reservoir where it is mixed with hot water (in order to melt the shavings). The hot reservoir water is directed back down to the ice, behind the auger, in a very thin sheet that immediately freezes over the very cold surface of the ice, leaving an almost perfectly smooth, frozen surface behind.
Use of hot water, reason #1:
Hot water efficiently melts the ice shavings that they pick up while scraping the rough surface of the ice so that it can be recycled. If cold water were used, the Zamboni water-reservoir would get bound up with chunky ice-water. Returning this slushy material to the ice would cause a rough imperfect surface.
Use of hot water, reason #2:
The clarity of the ice surface is as important as the consistency. Imperfections in the new surface will cause some opacity, detracting from the clarity of the new ice. This problem is minimized by the use of hot water, which liquifies most potential imperfections.
Use of hot water, reason #3:
If the water came out cold, the roughened surface left by the auger, might not fully melt to be incorporated into a solid clear ice surface. Also, any shavings or chips, left on the ice, might not be melted, and would form imperfections in the ice surface.
These machines rely on the relatively large surface area of the shaved ice and on the rate of heat transfer in water, to melt the shaved ice in preparation for resurfacing.
Warm water can (under certain rare circumstances) freeze faster than cold water. But Zamboni machines do not rely on this phenomenon.
You can observe the areas where the Zamboni cannot reach (along the edges of the curved areas), and see how the areas covered by the Zamboni differ from these relatively untreated areas.

Whatd they use before the zamboni?
Barrel of hot water skated around the rink
Why do you have to wait for hot water after someone just took a shower?
When someone takes a shower, the hot water tank replaces the water used with cold water. It takes the hot water heater some time (which varies with each heater) to heat the newly filled tank. The hot water is always replaced by cold as you use it, but you don't notice it as much when you use smaller amounts or, like dishwashers and washing machines, use the hot water in intermittent amounts.
Why is it more expensive to use a washing machine on a hot cycle?
Using a washing machine on a hot cycle can be more expensive because it requires more energy to heat the water to a higher temperature. This extra energy consumption adds to the overall cost of running the machine.
Do you use hot or cold water for water toys?
Some toys use cold and others use hot but what i would do is look and see what it uses. But i usually use warm water.
Why don't zamboni slip on ice?
Ice resurfacers use studded tires.
What is a hot water bath and how is it used?
A hot water bath is a bath with hot water. You use it to take a bath.
Do water vending machines use refrigerant?
Only if the water dispensed is chilled. Many water vending machines dispense large quantities into a user's container, jug or insulated cooler. Usually these bulk water vending machines serve ambient temperature filtered water and there is no refrigerant in these types of machines.
How do you keep a can of hot water hot for 40min?
use insulation to keep the water hot for 40 minutes
What do fog machines use to create the misty effect?
Fog machines use a mixture of water and glycol-based fluid to create the misty effect.
Which kind of energy do you use to power a washing machine?
Most washing machines use electricity as the primary source of energy for operation. Some newer models may also incorporate energy-saving features or options for using hot water from a water heater.
Does a dishwasher use hot water or does it heat up the water put into it?
They use hot water and if it is not hot enough, the heating element used to dry the dishes will heat it to the right temperature.
Who invented the zamboni?
Most likely several NHL teams started to use the Zamboni at the same time since the Zamboni Company delivered 15 machines to various places in 1954. Among those places where Boston Garden, home of the Boston Bruins, but also several other NHL arenas.
