Heating ambient air in an uninsulated home rapidly exhausts battery reserves. Survival thermodynamics mandates: heat the human body directly, not the room.
Consolidate the entire household into a single bedroom. Seal door sweeps with rolled towels and hang blankets over windows.

Unvented hydrocarbon combustion produces Carbon Monoxide (CO)—a colorless, odorless, tasteless gas that displaces oxygen in blood hemoglobin, causing unconsciousness and death. A CO2 air-quality monitor will not alarm for lethal carbon monoxide. Always open a window 5–10 cm for positive cross-ventilation when operating camping stoves.
