Zone 2: Hot-Humid Climate

About Climate Zone 2

Climate Zone 2 includes hot and humid regions that experience mild winters with occasional cool periods. Heating is needed for 1-2 months per year, and temperatures rarely drop below freezing for extended periods. Propane furnaces in Zone 2 operate at a fraction of their northern counterparts, making heating a small portion of overall propane consumption. Water heating, cooking, and outdoor appliances account for a larger share of propane use in this zone. The combination of warm climate and moderate propane demand means homeowners in Zone 2 typically use propane tanks of 250 gallons or less unless they have pool or spa heaters. Propane prices in Zone 2 states are generally moderate, benefiting from Gulf Coast production proximity in Texas and Louisiana.

States in Zone 2

The following 3 states fall within Climate Zone 2. The table shows each state's Heating Degree Days, average propane price, and estimated annual propane cost for a standard full-home setup (80K BTU furnace, 40-gallon water heater, cooking range, and clothes dryer).

Heating Efficiency Tips for Zone 2

Zone 2 homes need minimal heating investment. A properly sized 60,000 BTU furnace or even supplemental space heaters handle the brief heating season efficiently. Focus spending on water heater efficiency and outdoor living appliances.

Insulation Requirements for Zone 2

Zone 2 requires R-13 walls and R-38 ceiling insulation. These modest levels are sufficient for the mild heating season. Ensure windows and doors are sealed to prevent humid air infiltration during the cooling season, which incidentally helps during the brief heating periods.

Propane Consumption Patterns in Zone 2

Homes in Zone 2 experience relatively flat propane consumption throughout the year since heating is a minor component. Water heating, cooking, and outdoor appliances drive consistent year-round usage. Pool and spa heaters, if present, may actually increase propane consumption during the swimming season (spring through fall), creating an inverted seasonal pattern compared to northern zones. Delivery scheduling is straightforward with 1-3 fills per year depending on total consumption.
