How to heat your home when the power is out – 6 life-saving ways to stave off cold if disaster strikes

Cold weather is bad enough without power cuts, but add an outage on top of it and you only have so long before you are shivering in your own home.

A cold house does more than make you uncomfortable, however. Leave a house unheated for too long and you risk frozen pipes and mold growth. Worse, it can severely impact your health – especially that of young children, elderly and vulnerable.

Here, heating experts and contractors reveal 6 life-saving solutions to help you stay warm and prepare your home for an emergency.

How to heat your home when the power is out

You have a far better chance of keeping your home warm in a power outage when you prepare a home for a power cut ahead of time and get ahead of any disaster.

1. Focus on one room

Max Veggeberg, CEO and founder of Tetra begins, ‘The safest and most efficient way to heat a home during a power outage is by focusing on retaining and generating warmth. Begin by moving to a well-insulated room with minimal windows, and closing interior doors to other rooms containing heat.’

Focusing most of your efforts in one room will ensure your household stays healthy, which is by far the most important factor in dire situations such as a cold weather power cut, especially if you have not had the chance to prepare your home for a freeze or severe weather ahead of time.

2. Keep doors closed

When trying to heat your house when the furnace goes out, it helps to close all the doors – including the internal doors.

Isolating rooms and creating smaller spaces makes them easier to heat, helping to retain warmth more easily.

3. Block drafts

Just as you would keep a poorly insulated home warm, your next step would be to draft-proof your home.

Brandon Young, CEO at Payless Power says, 'The most important thing is to insulate your house. Weatherstrip or towel-seal the doors and windows shut off unused rooms, and huddle together in the warmest area. It's surprising how much of a difference this may make. Heavy drapes [with some curtain hacks for a warmer home], carpets, and quilts can do the trick.’

If you don't have any draft excluders you can use old pillows, cushions, or thick throws to physically block the gaps.

4. Use a portable generator

If you live in an area prone to power cuts or extreme weather, it's definitely worth investing in a portable generator, particularly when preparing your home for a snowstorm.

Brandon Young says, ‘A couple of the best options include using a portable operating generator to power the best electric space heaters.

‘Just remember to safely set up the generator outside – not inside or within a garage – and use a space heater with certain key features, including tip-over protection. This will be great if you don't have to heat a large area in your home and already have a generator.’

5. Stock up your stove

Brandon Young continues, ‘If you have a wood burner stove, a pellet stove, or a gas fireplace, you are in good shape. Such nonelectric sources of heat will maintain temperatures in large areas, even at the time of an outage. Be aware that pellet stoves may require a battery backup to work – so better check now for an emergency.’

Joel Worthington, president at Mr. Electric, a Neighborly company warns, however, ‘Homeowners should ensure proper ventilation when using gas or wood-burning heat sources to avoid carbon monoxide poisoning. Always follow manufacturer recommendations when operating generators.

'Keep flammable materials away from heaters and never leave them unattended. Homeowners should ensure all smoke and carbon monoxide detectors [availible at Walmart] are in good working order.’

6. Think long-term with solar

It isn't a quick fix, but now is as good a time as any to start thinking about eco-home improvements such as installing solar power panels. This can help with both eco-heating and eco-cooling as the weather becomes more extreme.

Kristina Zagame, senior researcher in home electrification at EnergySage advises, ‘If power goes out, a solar panel system with battery storage can keep your HVAC running. Extreme weather and major outages are becoming increasingly common across the U.S.

‘When the power grid goes dark, the house with solar and storage will be the only one with its lights still on. It’s a solution that can save you from costly disruptions like losing heat, spoiled food, and property damage.’

FAQs

What is the most affordable way to heat a home without power?

While they have a significant upfront cost, propane heaters can be particularly efficient at heating your home without power as gas is relatively affordable to replace. Be aware, however, that you need to opt for an indoor-specific gas heater and ventilate the space to prevent irritating your airways.

Of course, it also helps to take personal measures to stay warm in freezing conditions. Wearing lots of thin layers on top of one another will help to trap heat, especially if you use natural materials such as wool (including cashmere).

It can also ease the chill to leave your heating on overnight in freezing weather if you are concerned about potential power cuts. If you can thoroughly heat your home in the run-up to a cut, you are more likely to be able to keep it warm until the power comes back on.
