Winter camping can be magical, but staying comfortable on the road makes the difference between a memorable trip and a miserable one. If you travel in cold weather, choosing the right RV Heaters helps you stay warm, safe, and energy-efficient so you can focus on the scenery, not the chill.

This guide points out options for different rigs and budgets — from compact portable propane units to full furnaces — so you can pick the heater that matches your space, power setup, and travel style.

Top Picks

How We Picked These RV Heaters

When you’re choosing RV Heaters, you want real-world performance and safety. We evaluated options by: fuel type and availability (propane, diesel, electric), heating output (BTU or watt rating) and coverage area, safety features (ODS, tip-over shutoff, sealed combustion, CO/venting needs), installation complexity (portable vs.

built-in), power draw and runtime (critical if you boondock), weight and portability, user controls (thermostat, remote, app), reliability and customer feedback, and overall value for the intended use. We prioritized heaters that balance warmth, safety, and practicality for life on the road so you can pick a solution that fits your RV and travel plans.

Mr. Heater Portable Buddy MH9BX

If you travel in an RV or camp in cold weather, this is one of those RV Heaters you’ll be glad you packed. It’s compact, has a fold-down handle, and puts out serious radiant warmth — the 4,000–9,000 BTU range means you can nudge the temp up gently or blast heat when you need it.

You can run it from a 1 lb cylinder for short trips or hook it to a 20 lb tank with an optional hose and filter for longer stays. Safety features like an oxygen-depletion sensor and a tip-over shutoff give you peace of mind, and the piezo igniter makes starting quick and match-free.

Use it for everyday chilly mornings in your RV, warming a workbench, or special occasions like tailgates, ice fishing or a winter picnic. If you want a simple, reliable propane heater that actually moves heat where you sit, this is a solid, practical pick.

What People Say

People highlight how quickly it warms small spaces, its portability for trips, and reliable safety features — reviewers often mention long-term satisfaction and real-world use in tents, RVs and workshops.

Long-Term Cost Benefits

Because it runs on propane and offers up to 6 hours on low, you’ll often spend less than running an electric space heater for short trips. Using a larger 20 lb tank with a hose can stretch runtime and reduce per-hour fuel cost compared with many disposable can setups.

Return on Investment

You get a durable, multi-use heater that can double as emergency heat for your RV, workshop or tent. Over a few seasons the ability to use refillable tanks, plus lower electricity usage, makes it a cost-effective addition to your gear.

Situational Benefits

Ease of Use

Versatility

This heater covers a wide range of uses — from quick spot heating in an RV to weekend camping, workshops and tailgates — and works with both small disposable canisters and larger tanks.

Energy Efficiency

On low (4,000 BTU) it can run about 6 hours; on high (9,000 BTU) about 3 hours. Fuel burn rates are roughly 0.044 gal/hr at low and 0.099 gal/hr at high, so you can plan fuel needs precisely.

Problem Solving Ability

Solves the ‘too-cold’ problem in small enclosed areas where electric heaters struggle — reviewers report rapid temperature gains even in poorly insulated spaces and reliable operation in winter builds like skoolies or dome tents.

Indoor / Outdoor Usability

HCALORY Toolbox 2 Diesel Heater

If you like taking cold-weather RV trips, this is one of those RV Heaters that feels like a game changer. It’s a toolbox-style diesel air heater with a 6 L tank built in, so you don’t have to wrestle with external fuel cans every time.

You can run it from vehicle power or plug it into AC at a park — plus the Bluetooth app and altitude mode mean it adapts to high-elevation runs without much fuss. In day-to-day use you’ll appreciate how quickly it puts out warm air for a small camper or converted trailer, and for longer outings it’s handy as a parking heater to take the chill off before you climb in. It’s not silent and you’ll want to mind exhaust routing, but if you want something portable, powerful and controllable from your phone, this is a solid pick.

What People Say

People praise the heater’s strong, reliable heat and the convenience of app control and a compact toolbox form. Reviewers note it’s easy to service and great for camper conversions, though you’ll want to plan exhaust routing and optional ducting.

Long-Term Cost Benefits

Diesel burn rates quoted at roughly 0.036–0.1 gallons per hour mean you’ll use less fuel than many older parking heaters; being able to run from vehicle 12V or AC also reduces reliance on campground electric or portable propane. Over a season, that efficiency pays off if you use it regularly.

Return on Investment

You’re buying more than a one-trip gadget — this doubles as a parking heater, emergency heat source, and workshop warmer. If you use it across a few winters for camps, truck stops and pre-warming your RV, it quickly offsets its purchase price through saved motel nights, reduced engine idling, or less reliance on more expensive fuel options.

Situational Benefits

Ease of Use

Versatility

This unit covers a lot of bases — as one of the more portable RV Heaters it works for parked RVs, truck cabs, converted trailers and even as a temporary workshop heater thanks to its AC/DC options and the toolbox-style tank.

ProCom ML100TBAHR Propane Heater

If you’re looking at RV Heaters, this ProCom is the kind of unit that quietly makes cold nights a lot more comfortable. It’s a ventless 10,000 BTU blue‑flame heater with a built‑in thermostat, so once you set a temperature it cycles on and off to keep the space steady. It includes a 10 ft hose and regulator to run from a standard 20 lb propane cylinder and the slim wall‑mount design saves floor space in a small RV or camper.

For daily use it’s great for warming a living area or bedroom without drawing shore power; for special outings it’s perfectly suited to hunting cabins, ice houses or weekend boondocking when you want reliable heat without firing up the vehicle engine. A few reviewers mention it can be picky to light the first time and that you should use CO/LP detectors and crack a window for ventilation, and it’s not approved in California or Canada—so check local rules.

If you want something simple, efficient and effective for compact spaces, this is a sensible choice.

What People Say

People say it heats small RVs and hunting shacks well, uses less propane than some factory furnaces, and is straightforward to install with the included hose and regulator.

Because it runs on propane and claims very high vent‑free efficiency, you’ll typically burn less fuel than older or less efficient heaters. If you replace an inefficient RV furnace or avoid motel nights by staying warm in your rig, the savings add up over a season.

Return on Investment

If you use it regularly for winter trips, the unit can pay for itself by cutting propane use compared with older furnaces, reducing engine idling for heat, and letting you comfortably boondock—practical savings across a few seasons.

Situational Benefits

Ease of Use

Versatility

This is a practical entry among RV Heaters—you can use it in trailers, small motorhomes, hunting cabins, ice houses or as a temporary workshop heater. It’s not a one‑size‑fits‑all if you need approved equipment for every jurisdiction, but for permitted indoor, well‑ventilated small spaces it’s versatile and space‑saving.

VEVOR 8KW Diesel Heater

If you’re shopping RV Heaters and want something that actually heats fast without a lot of fuss, this VEVOR 8 kW diesel unit is worth a look. It’s an all‑in‑one heater with a remote and clear LCD so you can preheat your camper from outside, and the sandblasted aluminum heat exchanger promises heat in about ten minutes.

For everyday use you can warm your living area, preheat the engine, or run it as a dry supplemental heat source while boondocking. For special trips — rooftop tents, hunting camps or snowy overland routes — the portability and long runtime from a 5 L tank (several hours on low) make it handy. A few folks point out you’ll need to plan exhaust routing and be aware of diesel smell, but if you like simple, fuel‑efficient heat without rewiring your rig, it’s an easy tool to keep cold mornings from ruining the day.

People who use this heater appreciate how quickly it warms a space and how little fuel it uses compared with alternatives. Reviewers mention strong heat output, the convenience of remote or app control, and practical tips like elevating the unit for exhaust routing and carrying a spare fuel pump if you’ll be away from parts.

Long-Term Cost Benefits

Because the heater runs efficiently and consumes as little as 0.16 L/h at low settings, you’ll burn far less diesel than a vehicle idling for heat or some older furnaces. Over a season of regular winter trips that adds up — fewer stops for propane or motel nights and lower engine run time.

Return on Investment

If you use it every cold season for weekend trips or to avoid running your engine for heat, the fuel savings and extended comfort can cover the purchase cost in a few trips, especially compared with the ongoing cost of propane or motel stays.

Situational Benefits

Ease of Use

Versatility

As an entry in RV Heaters, this diesel unit is surprisingly adaptable — use it on vans, truck campers, trailers, in rooftop tents, or for temporary workshop heating. It’s not a permanent HVAC replacement but works well as a portable, high‑output supplemental heater.

Energy Efficiency

Manufacturer specs and reviews point to low fuel use: roughly 0.16–0.62 L/h depending on output, with the 5 L tank providing several hours on low settings. In practice reviewers report long runtimes and lower fuel costs versus idling or running less efficient heaters.

Problem Solving Ability

This heater solves the basic problem of staying warm on cold trips without relying on shore power. It’s especially useful if you need dry heat, want to preheat a space, or need a portable option that won’t drain your RV’s main systems.

Camco Olympian Wave-3

This little Wave-3 is one of those RV Heaters that makes cold mornings actually enjoyable. You can set it on low for gentle, efficient warmth or crank it up when you want the space to feel toasty fast.

Because it’s catalytic, there’s no open flame or noisy fan — that means quiet operation and more comfortable nights without draining batteries. It’s compact enough to move between a truck camper, small trailer, or a cozy corner of your motorhome, and you can mount it or use the optional legs.

For everyday chilly starts, weekend trips, or a winter weekend getaway where you don’t want to run the main furnace constantly, it’s a practical and versatile choice you’ll reach for again and again.

What People Say

Owners praise the Wave-3 for quietly warming small rigs without battery drain and for fitting into tight spaces; several note it’s surprisingly powerful for its size but you may need to buy the hose/regulator separately.

FAQ

How Do I Choose The Right RV Heater For My Space?

Choosing an RV heater starts with knowing your space and priorities: what you want powered, how quickly you need heat, and whether you want combustion or electric. As a rule of thumb aim for about 20–30 BTU per sq ft depending on insulation — that helps you compare options like portable propane units that deliver 4,000–9,000 BTU or a 35,000 BTU ducted furnace for larger rigs.

Propane and diesel models give high output and run without shore power, with something like the Mr. Heater Portable Buddy offering indoor-safe radiant heat for roughly $75.91, while diesel parking heaters and ducted furnaces cost more up front but are efficient for long trips. Electric wall or built-in units like the Suburban electric heater around $106.65 or smart PTC units like the Dreo around $99.99 are simpler to install and quieter but need reliable 120 V power and draw much more electricity.

Think about fuel availability, noise, how long you’ll run the unit, and safety features; prioritize heaters certified for indoor use or with Oxygen Depletion Sensor and tip-over protection if you plan to use combustion heaters inside the RV.

Are Propane And Diesel Heaters Safe To Use Inside My RV?

You can safely use combustion heaters inside an RV if you follow manufacturer instructions and take precautions: always use heaters certified for indoor use or vented designs, keep ventilation (a small cracked window or vent), install and test a reliable CO detector and propane leak detector, and place the unit on a stable surface away from flammables. Units like the Mr. Heater Buddy include ODS and tip-over shutoffs which greatly reduce risk, but you must check all gas connections for leaks and, when using a 20 lb tank with a portable unit, use a fuel filter as reviewers warned about oil or contaminants damaging the regulator.

Never ignore blocked exhaust or unusual smells, and avoid leaving unvented combustion heaters running in totally sealed tiny spaces overnight unless the unit is specifically rated for that use and your detectors read normal levels.

What Practical Tips Keep My Heater Reliable During Winter Trips?

Prepare before you leave: test the heater at home, inspect hoses and fittings, and carry spare parts like a fuel filter, extra glow plug or pump if you have a diesel unit. For propane units remember to purge air when you swap tanks by holding the pilot control until the line is bled, and if you plan to use a 20 lb tank outside run a quality hose and filter between the tank and heater.

For diesel parking heaters expect higher start-up power draw (often ~120 W during ignition then much lower while running) so plan battery or shore power accordingly and consider mounting the heater so exhaust piping is routed safely; many users pipe the diesel unit’s exhaust outside to reduce noise and smell. Clean and store heaters per the manual, check for soot or oil contamination, and keep CO and LP detectors in date.

If you value convenience, choose models with thermostats or app control for timed warmups, but for longevity and safety prioritize correct installation, regular maintenance, and following the manufacturer’s safety steps like securing vents and avoiding combustible clutter near the heater.

Wrapping Up

Choosing the right heater means thinking about fuel, space, and safety. Portable propane units like the Mr. Heater Buddy are compact, fast and ideal if you need heat now and portability matters.

Diesel and ducted furnaces (HCALORY, VEVOR, FOGATTI) give longer-range heating for conversions and larger coaches, but require installation and venting considerations. Electric smart wall heaters (Dreo) and built-in electric fireplaces (CONTOURE) are simplest if you have reliable shore power.

Consider what matters most to you — portability, runtime, installation, or raw output — and match the heater to your rig and how you camp. With the right RV Heaters, you’ll spend less time managing cold and more time enjoying winter trips in comfort.
