Are you using wood, coal, oil, electricity , propane, natural gas WHAT is the BTU of the natural gas ( Varies from 900 -1,200 BTU per CU FT) and oil #2 can vary from 138,000 - 140,00 BTU per gallon) and how much are you paying per THERM=Also various countries and cities have different charges for fuel=

∙ 12y agoThat's going to depend on so many things that you haven't specified, like
-- the initial temperature of the water
-- the temperature to which it's heated
-- the method of heating
-- the fuel used to do the heating
-- the cost of the fuel that day
-- the efficiency of the method
-- the container the water is in

How much does 1 gallon of leaves weigh?
You can't really say how much a gallon of snow will weigh without knowing the density of the snowfall. However, a general rule of thumb used for determining precipitation for snowfall is a ratio of 7 to 1. So, if you get seven inches of snowfall in the winter, it will be equivalent to 1 inch of rainfall. Since you can't truly determine the density based on a depth, it is probably safe to assume that the volume ratio for snow to water is also 7:1. A gallon of water weighs about 8.33 lbs, so using my logic, which is based more on rules of thumb than science, a gallon of snow will weigh 8.33/7 = 1.19 lbs. Compacted snow would obviously be much heavier though.A gallon of snow (which is mostly air around tiny ice crystals) will weigh much less than a gallon of solid ice.Fresh snow has a density of roughly 0.1 g/ml; packed snow can have a density around 0.3 g/ml; a solid block of ice has a density of about 0.92g/ml.
