Optimizing This Setup
To reduce propane consumption for the Cooking + Water Heater Only configuration, focus on the appliance that uses the most propane first, as that yields the greatest savings per unit of effort. In this setup, the propane stove/range is the largest consumer at 259.5 gal per year.
For non-heating appliances, the primary optimization strategy is efficient usage habits. For water heaters, lowering the thermostat to 120 degrees and installing low-flow fixtures reduces consumption. For cooking, matching pot sizes to burners and using lids conserves propane. For outdoor appliances, running equipment only when actively needed rather than leaving burners on standby prevents waste.
On the purchasing side, shopping among multiple propane dealers can reveal price differences of $0.30-0.50 per gallon in the same area. At 499 gal per year, a $0.30 per gallon savings translates to $149.70 in annual savings. Pre-buy contracts, cooperative buying groups, and larger tank installations that qualify for bulk pricing are all effective strategies for reducing your per-gallon cost.
