How Much Will You Save?

The following examples provide hypothetical energy and/or water savings totals associated with the use of high-efficiency commercial fryers, commercial hot food holding cabinets, and commercial steam cookers. It should be noted that the annual cost savings and payback periods are illustrative, and will depend on your actual energy, water, and equipment costs.

Example of Energy Savings Potential of a High-Efficiency Commercial Fryer

If a high-efficiency commercial fryer is purchased instead of a baseline model, annual cost savings will be $540 and the payback period of the investment will be just over 2 years for a gas-powered fryer, and the annual cost savings will be $73 with a payback period of 7.7 years for an electric-powered fryer.

Annual Per-Fryer Estimates Energy Consumption
Natural Gas
(MJ per year per fryer)
Electricity
(kWh per year per fryer)
Baseline* 138,000 14,585
High-Efficiency* 95,000 13,860
Savings 43,000 725
Energy Cost $0.48/m3 $0.1/kWh
Cost Savings $540 $73
Estimated Equipment Cost Differential $1,120 $560
Payback Period 2.1 years 7.7 years

A life cycle calculator and energy cost calculator for both gas and electric fryers are available from the Food Service Technology Center, as well as from ENERGY STAR. It should be noted that costs should be entered in Canadian dollars, as the defaults are based on U.S. dollar costs.

Example of Energy Savings Potential of a High-Efficiency Commercial Hot Food Holding Cabinet

If an 18 ft3 high-efficiency commercial hot food holding cabinet is purchased instead of a baseline model, annual cost savings will be $670 and the payback period of the investment will be 2 years.

Annual Per-Holding Cabinet Estimates Energy Consumption
(kWh per year per holding cabinet)
Baseline* 9 855
High-Efficiency* 3 154
Savings 6 701
Energy Cost $0.10/kWh
Cost Savings $670
Estimated Equipment Cost Differential $1,340
Payback Period 2.0 yr

Example of Energy Savings Potential of a High-Efficiency Commercial Steam Cooker

If a high-efficiency commercial steam cooker is purchased instead of a baseline model, the annual cost savings will be about $450 and the payback period of the investment will be 7.5 months for a gas-powered steam cooker, and the annual cost savings will be $375 with a payback period of 7.4 months for an electric-powered steam cooker.

Annual Per-Steam Cooker Estimates Energy Consumption
Natural Gas
(MJ per year per steam cooker)
Electricity
(kWh per year per steam cooker)
Baseline* 77,545 7,868
High-Efficiency* 41,780 4,120
Savings 35,765 3,748
Energy Cost $0.48/m3 $0.1/kWh
Cost Savings $449 $375
Estimated Cost Differential $280 $230
Payback Period 7.5 months 7.4 months

In addition, replacing a conventional steam cooker with a connectionless model has the potential to save on water consumption, reducing water and wastewater costs. One field study demonstrated that replacing a small steam cooker with a connectionless model saved 1136 litres (300 gal) per day. 1
