10 Best Camping Tent Heaters 2025 in the United States

The Mr. Heater Big Buddy PRO Series is a solid choice for a camping tent heater, offering a powerful heat output that can warm spaces up to 450 square feet with adjustable settings ranging from 4,000 to 18,000 BTUs. This flexibility lets you control the heat easily depending on your tent size and weather conditions. It uses propane fuel, which is common and efficient for camping, and the heater is nearly 100% efficient, meaning most of the fuel turns into heat rather than wasting energy.

Portability is good—the heater weighs about 14 pounds and has a pedestal design, making it stable and easy to set on the tent floor or other surfaces. It also includes important safety features like automatic shut-off if it tips over, if the pilot light goes out, or if oxygen levels drop too low, which is crucial for indoor or enclosed tent use. At very high altitudes (above 7,000 feet), it might shut off, so it may not be the best choice for high mountain camping.

Some models recently no longer include a fan due to import tariff changes, so the heat distribution might be less even compared to fan-equipped heaters. Since it’s a radiant heater without a fan, it should be relatively quiet. It requires 4 D batteries to operate the ignition and offers three heat settings for steady warmth. This heater is well-suited for campers needing a reliable, safe, and efficient propane heater that works indoors or outdoors and can handle medium to large tents.

The Mr. Heater MH9BX-Massachusetts/Canada approved portable Propane Heater is a solid choice for outdoor camping, heating spaces up to 225 square feet with its 4,000- to 9,000-BTU radiant heat output. It is nearly 100-percent efficient and burns clean, making it environmentally friendly. Key safety features include an auto shut-off if tipped over, if the pilot light goes out, or if low oxygen levels are detected, ensuring safe use in various conditions.

The heater is portable with a fold-down handle and swivel-out regulator, making it easy to connect to a propane tank (not included) and transport. However, it should be noted that it may shut off when used at altitudes over 7,000 feet, which could be a drawback for high-altitude camping. While generally quiet, users should ensure only authorized accessories are used to avoid voiding the warranty and potential injury.

This heater is best suited for outdoor use and is a great option for those needing reliable, portable heat for camping trips or other outdoor activities.

The Amazon Basics Ceramic Space Heater is a compact and lightweight option designed primarily for indoor use, such as in your home or office. Measuring 5.8 x 3.4 x 6 inches and weighing only 1.4 lbs, it is easy to transport and can be placed on tables or desks without taking up much space. This heater uses ceramic coils to provide fast and efficient heating at 500 watts, making it suitable for quickly warming up small areas. It includes safety features like Tip-Over Protection, which automatically shuts the heater off if it gets knocked over, enhancing its safety for use around children or pets.

However, it's important to note that the heater is designed for indoor use only, which may limit its effectiveness in a camping tent setting where outdoor conditions can be more variable. Additionally, with a heat output of 500 watts, it may not provide sufficient warmth in very cold temperatures or larger spaces typically associated with camping. The heater operates quietly, which is a plus for maintaining a peaceful environment. It is powered by electricity, meaning you will need access to a power source. This could be a drawback if you are camping in an area without reliable electricity.

The Amazon Basics Ceramic Space Heater offers portability, quick heating, and essential safety features, but its indoor-specific design and reliance on electricity might not fully meet the needs of all camping scenarios.
