Mr. Heater Portable Buddy MH9BX
Type: Portable Radiant Heater. BTU Range: 4,000–9,000. Designed to heat up to 225 sq. ft.
This unit uses infrared radiant technology to warm objects and people directly rather than heating the entire air volume, which can be efficient in small camper interiors. Safety features include an improved tip-over switch and built-in protections typical of indoor-safe propane heaters. The integrated piezo igniter gives matchless startup convenience. As a compact, low-BTU option, it suits small travel trailers and pop-up campers where space and ventilation are limited.
Consider ventilation, carbon monoxide monitoring, and placement away from flammable materials when using any propane radiant heater inside a camper.

Type: Multi-Setting Portable Heater. BTU Levels: 4,000 / 9,000 / 18,000. Coverage up to 450 sq. ft.
This model provides a wider BTU range for flexibility between low-load overnight heating and higher output for quick warm-up. It can connect to larger propane tanks with an additional hose for extended runtime, making it suitable for longer trips or larger camper layouts. The single-knob control and piezo spark ignition simplify operation. Built-in safety includes automatic shutoff on tip-over.
Because of its higher output option, confirm your camper’s ventilation and follow manufacturer guidance for indoor vs. outdoor use at higher BTU settings.
Mr. Heater 20,000 BTU Blue Flame Vent Free
Type: Wall-Mounted Vent-Free Blue Flame Heater. Output: Up to 20,000 BTU for spaces up to ~700 sq. ft.
This vent-free wall heater is designed for steady room heating with an onboard thermostat and electronic ignition. It includes an oxygen depletion sensor (ODS) that shuts the unit off if oxygen levels fall too low, a critical safety feature for indoor propane appliances. The white finish and compact form make it practical for camper conversion installations where venting options are limited.

Installation requires a safe mounting surface and adherence to clearances, plus carbon monoxide monitoring. Check local codes and RV-specific regulations; some RVs restrict vent-free appliances due to moisture and combustion byproduct considerations.
DARTMOOR RV Tankless Water Heater
Type: On-Demand Tankless Water Heater. Output: 65,000 BTU, ~2.4 GPM flow. Designed for RV installations.
While not a space heater, onboard hot water is a key aspect of camper comfort. This unit provides continuous hot water for showers and sinks and uses staged combustion for stable temperatures up to 124°F. Safety features include protections for dry heating, flameout, overheat, and anti-freeze. It’s optimized for RV environments, able to perform at higher altitudes and with a shower kit and control panel for integrated operation.
Installation requires matching existing water and gas connections, proper exhaust/vent cutout or door interface, and ensuring 12V power for controls. Tankless units save space and remove the need for a separate storage tank, a benefit in compact campers.
KINGRVER 65,000 BTU RV Tankless Heater
Type: High-Output Tankless Water Heater. Output: 65,000 BTU, very low 0.5 GPM activation pressure.
This tankless unit emphasizes low-pressure activation and altitude capability, useful for remote or mountainous camping. Automatic freeze protection activates below specified temperatures, which benefits cold-weather camping. It is designed to be compatible with common RV cutouts and offers optional door kits for retrofit installations.
As with other tankless models, ensure installation clearance, correct propane inlet sizing, and 12V supply for operation. Consider required door size or purchase optional door kit when retrofitting an older access opening.

Buying Guide For Propane Heaters In Campers
Types Of Propane Heating Options
- Portable Radiant Heaters (e.g., Buddy): Directly warm occupants and nearby surfaces; efficient in small enclosed spaces but require careful placement.
- Portable Multi-BTU Heaters: Offer variable output for flexibility; suitable when you need different heat levels for varied conditions.
- Vent-Free Blue Flame Wall Heaters: Provide whole-room warmth and thermostat control without external venting; check camper compatibility and moisture concerns.
- Tankless Propane Water Heaters: Not space heaters but essential for onboard hot water—choose for continuous showers and dishwashing without a tank.
Key Performance Considerations
- BTU Output: Match BTU to camper volume. Small campers often need 4,000–9,000 BTU; larger trailers or open floor plans may require 12,000–20,000 BTU or more.
- Heating Method: Radiant units heat people/objects directly and are efficient in drafty spaces; convection or blue flame units heat air for more uniform warmth.
- Runtime And Fuel Supply: Consider whether the heater connects to small 1-lb cylinders or to onboard tanks, and whether adapters/hose lines are required.
- Ignition And Controls: Piezo or electronic ignition reduces the need for matches. Thermostat control provides consistent temperatures and energy savings.
Safety And Installation
- Oxygen Depletion Sensor (ODS): Required on many indoor propane appliances to shut off when oxygen falls below safe levels.
- Tip-Over And Flame Failure: Portable units should include tip-over shutoff and flame failure protection.
- Vent-Free Considerations: Vent-free heaters produce combustion byproducts and moisture; ensure adequate ventilation and monitor carbon monoxide and humidity.
- Installation Requirements: Wall-mounted vent-free units and tankless water heaters may need permanent mounting, correct clearances, and gas line sizing. Follow manufacturer and RV code instructions.
Practical Camper Considerations
- Space And Layout: Measure available floor and wall space before choosing a unit. Portable heaters allow repositioning; wall units free floor space.
- Power Availability: Tankless water heaters and electronic ignitions may need 12V power—confirm your battery or converter capacity.
- Altitude Performance: If camping at high elevation, select units rated for altitude or with staged combustion to maintain stable flames.
- Cold-Weather Features: Look for freeze protection in water heaters and low-temperature operation specs for reliable winter use.
Comparison Perspectives
- Efficiency vs. Coverage: Radiant heaters are efficient for targeted warmth; vent-free and multi-BTU units better for whole-camper comfort.
- Portability vs. Permanence: Portable heaters suit renters or multi-use setups; permanent wall heaters and tankless units require installation but integrate seamlessly.
- Safety vs. Convenience: Higher-output heaters offer comfort but increase ventilation needs and monitoring; choose a balance aligned with your camping style.
- Hot Water Integration: If shower/hot water access is a priority, a tankless water heater provides continuous supply without the space penalty of a storage tank.
Final Purchase Checklist
- Confirm BTU rating appropriate for camper volume.
- Verify indoor-safe certification and presence of ODS or equivalent safety features.
- Check ignition type and power needs (piezo, battery, 12V).
- Ensure proper hookups: propane fittings, hose lengths, and door/cutout compatibility for tankless units.
- Plan for carbon monoxide and combustion monitoring devices when using propane appliances indoors.
