How to Keep a Tent Warm

Bedding, insulation, heated blankets, and campground power for cold-weather tent camping.

Start with the bed and bedding, then add heat. At an electric campsite, the oil-filled radiator we use overnight provides steady, thermostatically controlled warmth, and an electric heated blanket handles spot warmth wherever you're sitting or lying.

Insulate the Bed

Add layers between you and the cold air in the mattress. Our setup includes a shag carpet strip above the airbed beneath the bedding.

Use Warm Bedding

We use a flannel sleeping bag and a plush fitted sheet as part of the cold-weather bed setup.

Add a Heated Blanket

An electric heated blanket with adjustable heat settings gives localized warmth without trying to heat the entire tent.

Oil-Filled Radiator

The oil-filled radiator we use overnight cycles on and off with its thermostat to maintain steady warmth.

See our camping bed setup for the complete sleeping system.

Use the Heated Blanket for Spot Warmth

The heated blanket is useful when you want warmth where you are sitting or lying rather than trying to warm the whole tent. It has adjustable heat settings and an auto-off timer, so it is not left running unattended overnight.

At an electric campsite, see Camping With Electric Hookups for the campground outlet setup and circuit-load basics.

Electric Campsites Make Cold-Weather Camping Easier

An electric campsite is what solves cold-weather camping: it lets you run the radiator and heated blanket all night without draining a portable power station, and it gives you a place to recharge batteries and other camping electronics during the day.

Common Questions

Is a heated blanket alone enough, or do I still need a space heater?

A heated blanket keeps you warm in bed, not the air around you. If you want the whole tent warm and not just where you are lying, you still need the oil-filled radiator or a similar electric heater.

Can I heat a tent without an electric campsite?

It is possible with a large enough battery power station, but a space heater draws far more power than a heated blanket or fan. Check the heater's running wattage against the power station's usable capacity before depending on battery power for more than a short run.

Is an electric heater safe to run inside a tent overnight?

An electric oil-filled radiator is safer than a fuel-burning heater, since it does not produce carbon monoxide and most models have a tip-over and overheat shutoff.

What is the easiest way to stay warm without a space heater?

Layer the bed first: insulation like a shag carpet strip under the sheets, a flannel sleeping bag rated for the temperature you expect, and a heated blanket for spot warmth. That combination handles most cold nights without needing a full room heater at all.
