Hi pizza Guy :

GM: I am not a technician. I phoned the Wayne burner company several years back when Middleby began to advertise a 30 % reduction in operating cost. At that time I was told the old burners burned about 80 % of the gas and newest burners burned 98%. I had no way of coming up with those figures on my own. unfortunatly I do not recall who I spoke to. I will check on that again.

Note the statement by MF&B restaurant systems “We have used an optional modulating burner that is an industry first to modulate both gas and combustion air. Our tests show this is a real world savings of about 25% compared to similar models.”

The would appear to indicate a more efficient burning of gas if savings are achieved. As to wether this results in a greater % of gas being burned I do not know. I was told Wayne was developing even more efficient burners but did not know how efficient.

GM: Again I do not claim that 110 volt is better than 220 volt only that the 110 volt system on the newer ovens costs less to operate than the 220- 240 Volt system on the middleby. I am not an electrician and only am passing on information provided to me,

See below.

This is a chart provided to me by the Wolfe Electric CO. It did not transfer to this medium as a chart but the figures are the same

Energy Consumption Comparison between the Middleby PS360 and XLT-3255 These ovens have the same size baking chamber production is the same if done at the same time and temperature.

XLT-3255 single Gas fired oven.Electrical power for blower & belt Voltage: 120 VAC–Amperage: 6.0 Volts x Amps) = Watts: = 720

Middleby PS 360 single Gas fired oven.Electrical power for blowers and belt. Voltage: 240 VAC-Amperage: 8 (Volts x Amps) = Watts: = 1920

If a restaurant is open 12 hours per day for 360 days, that is 4,320 hours per year.

Watts/year:

XLT = 3,110,400 / 1000 = 3,110.4 KWH/year*

Watts/year:

MM PS360 = 8,294,400 / 1000 = 8294.4 KWH/year**

XLT per year electrical cost Year = $258.16

MM PS-360Year electricity consumption = $688.43

- We assumed a 12-hour day, and a 360-day year. ** The US national average cost for electricity is 8.3 cents per kilowatt-hour (KWh). A Watt is a measure of electrical power and equals volts times amps. A watt-hour is the number of watts used per hour. For example, if you used ten, 100-watt light bulbs for 1 hour, you used 1000 watts for 1 hour or 1 KWh.

The ps360 oven uses over 2 and 1/2 times the amount of electricity that the XLT3255 uses. Or, stated another way, the XLT3255 ovens are 266% more efficient electrically. This equates to an annual savings of $430.27 per oven. As electricity rates continue to increase, it is conceivable that annual savings will approach $500.00 per year per oven.

If the above is not correct let me know.
