Winter Emergency Prep on a $150 Budget
Cold weather kills more people than heat in the US. Here's how to prepare your household for winter power outages, storms, and heating failure — affordably.
By ReadyNotRich · Emergency preparedness guidance for everyday households · Published 11 June 2026
Cold weather consistently kills more Americans than hurricanes, tornadoes, and floods combined, according to the CDC. The winter of 2021 saw Winter Storm Uri kill over 700 people in Texas alone — most from hypothermia in their own homes. Yet winter preparedness is one of the most actionable and affordable areas of emergency prep. $150 can fully winterise a household.
The Real Risks of a Winter Power Outage
During a winter grid failure, indoor temperatures can drop below freezing within hours in poorly insulated homes. The elderly and very young are most at risk, but hypothermia can affect any adult in a cold enough environment. A core body temperature below 35°C (95°F) constitutes hypothermia — and it can occur at indoor temperatures of 10°C (50°F) if you're sedentary and lightly dressed.
Layer, Don't Heat (~$30)
Your first line of defence is warmth without electricity. A quality sleeping bag rated to -10°C and emergency mylar blankets can keep a person warm even in a very cold room. The mylar blanket trick: sleep inside your sleeping bag, with a mylar blanket between the bag and mattress to reflect heat back. This setup is good to -20°C for most adults. Cost: under $40.

Retain 90% of body heat. Waterproof. Takes up almost no space in a bag.
The One-Room Strategy
During a prolonged power outage in winter, abandon trying to heat your whole home. Choose one interior room — ideally small, with few windows — and insulate it. Hang blankets over windows and doorways. Body heat from two or three people in a small room can raise the temperature by 10°C over an hour. This is how people survived harsh winters long before central heating.
Safe Indoor Heat Sources (~$40)
A propane camping heater like the Mr Heater Little Buddy is safe for indoor use and runs for 5–6 hours on a small canister. Never use outdoor gas heaters or barbecues indoors — carbon monoxide poisoning kills dozens each year this way. Battery-powered carbon monoxide detectors are cheap and non-negotiable if using any combustion heat source indoors.
Food and Water in Winter Emergencies
Frozen pipes are a major risk — and a burst pipe can cause thousands in damage. Before a predicted freeze: insulate exposed pipes with foam lagging ($5 at any DIY store), let cold taps drip slightly to keep water moving, and know where your stopcock is. Keep at least 3 days of bottled water since frozen pipes can interrupt supply without warning.
Power for the Essentials (~$80)
A portable power station keeps phones and emergency lights running during a winter outage. The Jackery 240 can power a small heating pad, charge all devices, and run a CPAP machine — the most critical use case for medical households. At under $200, it's the single most impactful winter prep purchase for renters without a generator option.

The $150 Winter Prep Shopping List
Emergency mylar blankets 10-pack ($10), a -10°C sleeping bag if you don't own one ($35), a Mr Heater Little Buddy propane heater ($65), two CO detector batteries ($5), pipe insulation foam for exposed pipes ($8), and 6 gallons of stored water ($12 in food-grade jugs). Total: $135. The remaining $15 buys a week's worth of extra shelf-stable food.
Frequently asked questions
How do I prepare for a winter power outage?
Prepare for a winter power outage by storing emergency mylar blankets and a sleeping bag rated to -10°C, a safe indoor propane heater like the Mr Heater Little Buddy, a carbon monoxide detector, a portable power station for medical devices and phones, and 3–7 days of food and water that doesn't require cooking.
How cold does a house get during a power outage in winter?
A house loses approximately 1°C per hour during a winter power outage in cold weather, depending on insulation. In an uninsulated home, indoor temperatures can reach freezing within 4–6 hours in severe cold. The one-room strategy — heating a single small interior room — is far more effective than trying to heat an entire home.
What is the safest indoor heater for emergencies?
The Mr Heater Little Buddy is one of the few propane heaters certified for indoor use. It runs for 5–6 hours on a small canister and heats a small room effectively. Never use outdoor gas barbecues, charcoal grills, or outdoor propane heaters indoors — carbon monoxide poisoning kills dozens each year from this mistake.
How do I prevent pipes from freezing during a power outage?
Prevent pipes from freezing by insulating exposed pipes with foam lagging ($5 at hardware stores), letting cold taps drip slightly to keep water moving, and knowing where your stopcock is to shut off water quickly if a pipe does freeze. Store at least 3 days of drinking water before a predicted cold snap.
