Energy required to heat water calculator.

Assumptions base model has an efficiency that just meets the national minimum standard for gas and electric water heaters. To calculate the heat required determine the variables. M refers to the mass of the material. 98 c to 102 c this does not hold true any more.

Other units used to quantify heat are the british thermal unit btu the amount of heat to raise 1 lb of water by 1 o f and the calorie the amount of heat to raise 1 gram of water by 1 o c or 1 k. C refers to the specific heat of the material. 1 watt is approximately 3 412 btu per hour. 2 c to 2 c or from fluid to gas e g.

The following formula is used to calculate the power of heating element needed to heat a specific volume of water by a given temperature rise in 1 hour. It is approximately the energy needed to heat one pound of water by 1 degree fahrenheit. Energy stored or available in hot water can be calculated. Hi john it takes the same amount of energy to heat water from 48 degrees to 52 degrees as it takes to heat water from 58 degrees to 62.

Your selection of a water heater using gallon s per day will have a energy cost savings per water heater over an estimated 13 year life expectancy compared to the model. If we can calculate the volume of water and the required temperaure rise we can answer this question. The british thermal unit or btu is an energy unit. Heat energy the si unit of heat or energy is joule j.

Q m c δt. Read on to learn how to apply the heat capacity formula correctly to obtain a valid result. Water is often used to store thermal energy. Heat energy required to heat 700 gal can be calculated as follows.

Heat required 5810 lbs x 1 btu lb ºf x 120 ºf 55 ºf. Heat will transfer from a warm body with higher temperature to a colder body with lower temperature. You can calculate the energy required to raise the temperature of water or any given substance for that matter using this formula. Dt temperature difference between the hot water and the surroundings o c o f m mass of water kg lb m.

This specific heat calculator is a tool that determines the heat capacity of a heated or a cooled sample. 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. But when the state of water changes from solid to fluid e g. M mass of water heated 700 gallons 5810 lbs c p is the heat capacity of water 1 btu lb ºf given δt temperature difference 120 ºf 55 ºf.

δt refers to the temperature change that occurs. 1 btu 1 055 joules 252 calories 0 293 watt hour or the energy released by burning one match.
