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.
