| Total heat energy for the outage | |
| Propane needed | |
| In full 20 lb cylinders | |
| In exchange tanks (about 15 lb fill) |
Rates used: water 1.0 gal/person/day (FEMA/CDC), 0.50 gal/day per medium/large dog, 0.15 gal/day per cat. Heat load: square feet x 40-45 BTU/hr (Northeast climate zones 5/6). Propane: 21,500 BTU per lb. Real-world heater runtime is shorter than the math suggests - plan with margin. One tank warning: swap/exchange cylinders are commonly filled to about 15 lb rather than a full 20 lb, so count those at the exchange-tank figure - counting them as full 20s overestimates your fuel by about a third.
