Best Heaters for Teardrop Trailers (Propane, Electric and Diesel Options)

Heating a teardrop trailer comes down to three main options: propane heaters, electric heaters, and diesel heaters. In this guide we cover the best portable heaters for small campers, safety tips, and how to choose the right option for your setup.

Whether you are winter camping or just taking the chill off a cool fall evening, a portable heater can make a big difference in the comfort of your small camper. A note: most people do not camp in below zero temps and these heaters may not do the trick in extreme conditions.

How to Use a Heater Safely in a Teardrop Trailer

A good practice is to warm up your camper before you go to bed and again in the morning when you wake up. This is safer than running a heater while you sleep in a small space and will save on fuel. Your body heat will help warm a small camper as well.

Safety Tips for Heating a Teardrop Trailer

Maintenance. Follow the manufacturer’s instructions for cleaning and maintenance.

Ventilation. It may seem counterintuitive, but please make sure to crack a window or vent to allow fresh air to circulate. This will help prevent the buildup of carbon monoxide and condensation.

Carbon Monoxide Detector. Install a carbon monoxide and smoke alarm in your camper if you don’t have one already. It is also a good idea to carry a fire extinguisher.

Fire Hazards. Keep flammable materials away from the heater and make sure it is on a stable surface. Never leave the heater unattended and turn it off before leaving the camper. Electric heaters should be plugged directly into the wall outlet and not an extension cord or power strip.

Size and Wattage. Make sure the heater is the appropriate size and wattage for your camper or power source. You do not want an undersized heater that will struggle to heat your space.

By following these safety considerations, you can enjoy the comfort and warmth of a portable heater in your teardrop camper while ensuring the safety of yourself and others.

Electric Heaters for Teardrop Trailers

Electric ceramic heaters are a popular choice for small campers when you have shore power. They work by heating ceramic plates that radiate warmth into the surrounding area. They are typically quiet and energy efficient.

You will need an electric hookup, generator, or for smaller heaters, a power station like a Goal Zero to run this type of heater. Electric heaters should be plugged directly into the wall outlet and not an extension cord or power strip.

Lasko My Heat

This compact heater uses only 200 watts, making it a good option for running off a larger power station when you don’t have hookups.

Wall Outlet Electric Heater

This compact heater plugs directly into your AC socket and has a built-in thermostat and timer. Great for campsite hookups where you want set-it-and-forget-it warmth overnight.

Metkiio Portable Mini Heater

A cute little heater that uses as little as 400 watts and doubles as a small fan on warmer days. Added here for aesthetics as well as function.

Electric Fireplace Heater

I have a similar heater to this one and the faux fireplace flame makes it a very cozy way to heat up your camper. There is something about that warm glow on a cold night that makes the whole space feel more comfortable.

Propane Heaters

Propane heaters are the top choice for boondocking and off-grid camping. They are lightweight, portable, and do not require any electrical power to operate. We have used our Mr. Buddy to warm up both a tent and a camper.

Mr. Heater is the most popular brand for portable propane heaters and they make several sizes that work well in a small space. They use the small green propane bottles for fuel, and Mr. Heater sells an adapter hose to connect to a larger propane tank.

Mr. Heater Portable Buddy (9,000 BTU)

The step up from the Little Buddy and the most popular propane heater among teardrop and small camper owners. At 9,000 BTU it will heat a small camper quickly even on a cold night.

Mr. Heater Hose Assembly

If you want to connect your Mr. Heater to a larger propane tank instead of small canisters, this hose assembly makes that easy. Much more economical for extended camping trips.

Heat Powered Stove Fan

A nice add-on to any propane heater setup. This thermoelectric fan requires no power and sits directly on top of your heater to circulate warm air around the camper more efficiently.

Butane Heaters

Similar to propane heaters, butane heaters use a small butane canister for fuel. The Kovea Cupid is a popular option among campers who want a compact and portable heat source. These heaters have an open flame so keep them away from flammable materials and always use with ventilation.

Vented Propane Heaters

While this option may be overkill for most teardrops, if you are planning to do true winter camping the Dickinson Propane Heater is worth knowing about. The heater is vented out of the top or side of the camper (which involves cutting holes in your camper wall). It was originally designed for boats and provides clean, safe heat with no open flame inside the living space.

This is a permanent installation and a significant investment, but for serious cold weather campers it is the gold standard.

Diesel Heaters

Diesel heaters have become increasingly popular among overlanders, van lifers, and campers who want reliable heat without shore power or propane. They work by drawing a small amount of diesel fuel, combusting it in a sealed unit, and pushing clean warm air into your living space while venting exhaust safely outside.

Modern units from brands like Webasto, Espar, and more affordable options like Vevor can heat a small camper to a comfortable temperature even in very cold conditions. Once up to temperature they run quietly and efficiently on minimal power (typically 10 to 30 watts).

For a teardrop trailer, a diesel heater is a more permanent installation than a propane heater, but it offers the most consistent and fuel-efficient heat for extended cold weather camping.

Which Heater Is Right for Your Teardrop Trailer?

The right heater depends on how and where you camp most often. Here is a simple guide:

You camp mostly at campgrounds with electric hookups: An electric ceramic heater is your easiest and safest option. The wall outlet heater with a built-in thermostat is especially convenient for overnight use.

You boondock or camp without hookups occasionally: The Mr. Heater Portable Buddy is the most practical choice. It is affordable, widely available, easy to use, and puts out enough heat for a teardrop trailer. Just make sure to crack a vent and have a carbon monoxide detector.

You do extended off-grid or cold weather camping: A diesel heater is worth the investment. It is the most fuel-efficient option for longer trips and runs without propane canisters.

You want a permanent winter camping setup: The Dickinson vented propane heater is the premium option and the safest for overnight use since the combustion is sealed and vented outside.

For most teardrop campers, the Mr. Heater Portable Buddy paired with a carbon monoxide detector covers the majority of cold weather situations at a very reasonable price.
