You'd probably never get it to reach 90 degrees maybe 85 max but depends on the heater on average it would take 2-3 days so around 1000.00 dollars I'd guess.

To heat 1 gallon of water by 1 degree Fahrenheit, it typically requires about 8.34 BTUs. Therefore, the time it takes for 1 BTU to heat 1 gallon of water would depend on the power of the heating source. If, for example, a heater provides 1 BTU per second, it would take approximately 8.34 seconds to raise the temperature of 1 gallon by 1 degree Fahrenheit.

You would need to remove approximately 1200 BTUs of heat to convert a gallon of water to ice. There are 8.34 lb in a gallon of water, which converting to lb-moles is 0.463. The latent heat of crystallization for water is -2583.4 BTU/lb-mole. Multiplying the two together and you get -1197 BTUs, which means you need to remove that amount of heat to convert the gallon of water to ice.
Heating a gallon of water by one degree Celsius requires around 8,337 BTUs (British Thermal Units) of energy. Since 1 cubic foot of natural gas produces about 1,031 BTUs, you would need roughly 8 cubic feet of natural gas to heat a gallon of water by one degree Celsius.
3 gallons because it has more heat energy and it gets warmer
That depends on what the starting temperature of the water is,and what temperature you want it to reach.If you expect to get a number, you must first give the necessary numbers.
A certain heat degree.
a 462000-gallon boiler, unlikely to be found on the market :)
There is no degree Fahrenheit for heat.
This is a pretty straightforward calculation. By definition, a BTU is the amount of energy required to raise one pound of water one degree F. But you have one gallon of water, which weighs approximately* 8.34 pounds. So, you'd need 8.34 BTU to increase one gallon of water one degree F. Note how the amount of time was not important. Whether you heat the water slowly or quickly doesn't matter. You will still require 8.34 BTU to raise the temperature of a gallon of water one degree F. * I say approximately because the weight of water varies slightly with its temperature. Water is at its densest at 4 degrees Celsius (39 degrees F). A gallon of water at temperatures above and below that value will weigh less.
