WebWater is often used to store thermal energy. Energy stored - or available - in hot water can be calculated. E = c p dt m (1) where . E = energy (kJ, Btu) c p = specific heat of water (kJ/kg o C, Btu/lb o F) (4.2 kJ/kg o C, 1 Btu/lb m o F for water) dt = temperature difference between the hot water and the surroundings (o C, o F)) Physical units and Btu 1; Electricity: 1 kilowatthour = 3,412 Btu: Natural gas: 1 cubic foot = 1,039 Btu 2 1 therm = 100,000 Btu: Motor gasoline: 1 gallon = 120,238 Btu 3: Diesel fuel: 1 gallon = 137,381 Btu 4: Heating oil: 1 gallon = 138,500 Btu 5: Propane: 1 gallon = 91,452 Btu: Wood: 1 cord = 20,000,000 Btu 6 See more A British thermal unit(Btu) is a measure of the heat content of fuels or energy sources.
