The FSTC team compared the boiler-based steamers and their connectionless replacements at five locations: one in southern California (SC1/SC2) and four in northern California (NC1a/NC1b, NC3/NC4, NC5a/NC5b and NC6a/NC6b). Comparison examples of #1 (SC1/SC2) and #2 (NC3/NC4) used separate facilities from the same chain that had already installed replacements boilerless steamers for comparison. Since the menu items and food cooked were the same and it was determined from store records that the customer volume was equivalent, the two restaurants effectively could be compared to show a “before and after” savings effect from replacing a boiler-based steamer with a connectionless unit.
We offer a three year lease to own program at $185 a month. If you have a boiler steamer your average savings will be $250 a month, making the Alco steamer a net income gain.
OPERATING COST COMPARISON EXAMPLE #1 (SC1/SC2)
SC1 and SC2 were identical restaurants from the same chain, located less than 20 miles apart in neighboring towns in southern California. Table 2 and Figure 36 below show the comparative steamer water and energy costs in these facilities. The connectionless steamer cost $7 per year for combined water and sewer and $571 per year for electricity, totaling $578 per year. On the other hand, the boiler-based steamer cost $1,944 per year for water and $4,717 per year for electricity, for a total annual cost of $6,661. With a $6,083 per year difference in combined water and energy costs, the connectionless steamer would pay for itself within one year. Although variances in steamer production and kitchen operation may slightly affect the usage at each location, there was clearly an operational cost benefit to the boilerless technology.
OPERATING COST COMPARISON EXAMPLE #2 (NC1A/NC1B)
NC1a and NC1b were steamer installations operated within the same kitchen facility. Table 3 and Figure 37 show the steamer water and energy cost comparison between each steamer configuration. Operating 260 days per year, the annual utility costs were calculated to be $4,351 for the boiler-based steamer and $1,017 for the stacked connectionless steamers. The annual savings were approximately $3,334.
OPERATING COST COMPARISON EXAMPLE #3 (NC3/NC4)
NC1 and NC4 were two restaurants from the same chain. NC4 was already equipped with a replacement boilerless steamer and was used for comparison to the NC3 boiler-based steamer. Table 4 and Figure 38 show the water and energy costs of each steamer installation. The total yearly cost difference between the two installations was $780.
OPERATING COST COMPARISON EXAMPLE #4 (NC5A/NC5B)
In this restaurant, the NC5a boiler-based steamer was removed, replaced and compared with the NC5b boilerless steamer. Table 5 and Figure 39 show the water and energy cost differences between each configuration. The restaurant’s steamer retrofit resulted in an estimated yearly cost savings of $1,110 for water and $1,295 for electricity, for a combined yearly savings of $2,405.
OPERATING COST COMPARISON EXAMPLE #5 (NC6A/NC6B)
This restuarant replaced is NC6a boiler-based steamer with the connectionless steamer installation NC6b. The yearly operating costs are shown in Table 6 and Figure 40. The retrofit resulted ina $584 per year water savings and a $2,326 per year electricity savings, added together for a yearly operating cost reduction of $2,910
