Re:Help me budget utilities
I can't give you any info on the diesel gas side of things. But I can tell you I run through a 40# propane tank (~7 gallons @ 2.65/gal) per 5 days running a 15# fryer (which is small for a commercial fryer), and a 3' griddle (of which we usually only have 2/3 on). My water and greywater dumping is free. Well, the water is city water and I pull it from my landlord's system. I don't know about your locality, but I think as long as its potable water (moved in potable hoses), my tanks can be filled up anywhere. Greywater can be dumped into the local wastewater system (toilet). We use about 30 gallons of freshwater per day.
This is all on a cart, which is also has power. Our power bill is about $100-$120 per month. The bulk of this expense goes to refrigeration, exhaust fan operation, and AC.
