Electric Furnace Efficiency Calculation

Thus efficiency alone is not an indicator of operating costs.

Electric furnace efficiency calculation.

If you need more than 68 000 btu s we suggest either two electric furnaces with separate duct systems for each or a gas furnace. The only time you can rely on afue as a sole comparison is when comparing two furnaces with the same fuel type. An electric furnace is the more efficient of the two. Heat and energy efficiency.

Take a few minutes to use this savings calculator to find out how much money you can save in one year and in 20 years. Winchester 59045 btu 4 ton residential forced air electric furnace with ecm blower motor model me16cn21 18 1 439 36 1 439 36. Air conditioning and heat pump energy efficiency is measured by seer which stands for seasonal energy efficiency ratio. For example if a furnace has a listed input rating of 90 000 btu s and an efficiency rating of 80 it will produce 90 000 btu input x 80 efficiency 72 000 btu actual output.

Efficiency of proposed new furnace. Winchester 40 878 btu 2 3 5 ton mobile home electric furnace with emc blower motor model we30b4d 12. The higher the seer rating the more efficient your ac unit is and the less energy it consumes. Furnace efficiency the efficiency of a furnace is the ratio of useful output to heat input.

Remember that the larger the heating element the more power it will consume. Assuming an electric heater with 100 percent efficiency homeowners should expect to pay roughly 34 32 per million btus of heat. Installing an electric furnace. Set your store to see local availability add to cart.

You would be pretty disappointed if you replaced your natural gas furnace with an electric furnace hoping to save money in heating costs. Gas furnace ratings range from 55 to 97 percent. Then to calculate the output on a given gas furnace multiply it s efficiency rating by it s listed input rating to determine the actual btu output of heat. Most electric furnaces are offered in 7 000 10 000 btu increments so you just need to get close in terms of sizing.

2 5 1 direct method testing the efficiency of the furnace can be computed by measuring the amount of fuel consumed per unit weight of material produced from the furnace. The furnace efficiency can be determined by both direct and indirect method. It may have an annual fuel utilization efficiency afue rating as high as 100 percent. Natural gas is generally sold in therms where one therm is equal.
