VEVOR 8KW Diesel Heater
Type: 8 kW diesel air heater for campers, vans, boats and garages. The unit is rated for roughly 215–269 ft² and promises rapid warm-up.
Key features include a sandblasting aluminum heat exchanger for quick heat transfer, Bluetooth app control plus remote and LCD, and automatic altitude compensation up to 18,045 ft. The product targets users who need a robust heater for cold nights and variable elevation.
Installation requires routing fuel and exhaust and mounting the heater and ducting. The unit delivers forced warm air rather than radiant heat, so it heats cabin air quickly and maintains set temperatures via the controller. Suitable where diesel supply and battery capacity are available. Noise, ventilation, and fuel management should be planned before installation.
Sunster 8KW 12V 24V/110V Portable Diesel Heater

Type: Portable all-in-one diesel heater with built-in 6L tank and toolbox-style enclosure. Designed for vans, trucks and outdoor use with multiple power options.
Highlighted features: dual power wiring (12/24V DC and 110–240V AC) with automatic switching, Bluetooth intelligent control, remote and LCD, and an integrated fuel tank for portability. The sealed toolbox design aids weather protection and compact installation.
This heater is aimed at users who want mobility and the ability to run on vehicle power or shore power. The built-in tank reduces external plumbing but requires attention to ventilation and placement to avoid fumes. Preheating via app or remote provides convenience for cold-night startups. Plan electrical and fuel safety measures during installation.
VEVOR 8KW Diesel Heater All in One
Type: 8 kW diesel air heater with digital display and safety upgrades for RV and camper use. Rated for mid-size interiors and longer run use.
Features emphasize low fuel consumption (precision pump), a ceramic igniter for cold starts, and enhanced safety like a heat-insulated exhaust shield and leak-proof fuel cap. It includes a 5L tank and claims high combustion efficiency.

The design suits users prioritizing fuel efficiency and additional safety protections. Installation complexity mirrors other diesel units—mounting, fuel routing, exhaust and power must be addressed. Noise levels vary by model and fan speed. Diesel heaters provide steady forced-air warmth and are common for overnight heating in off-grid vanlife setups where diesel is available.
Mr. Heater MH9BXRV Buddy
Type: Portable radiant propane heater rated 4,000–9,000 BTU for small enclosed spaces up to about 225 sq ft. Designed with indoor-safe approval for many RV applications.
Key notes: clean-burning radiant heat, near 100% efficiency for direct warmth, and safety features including tip-over shutoff and low-oxygen sensor (ODS). The unit is simple to install—place on a stable surface and connect a propane cylinder per instructions.
Radiant heating warms objects and occupants directly rather than heating all cabin air quickly. Effective for spot-warming sleepers at night, but requires adherence to ventilation and propane safety guidelines. Not a continuous long-term solution for very cold environments without ventilation and carbon-monoxide awareness. It is compact and often chosen for simplicity and portability.
Xtreme Heaters Boat, Cabin, & RV Heater
Type: Electric portable space heater designed for small spaces such as boats, cabins and camper vans. Emphasis on quiet operation and placement flexibility.
Features include an airflow intake on top allowing placement against walls and carpets, a stable low-profile base, tip-over automatic shutoff, and quiet fan operation. The heater is focused on safety and convenience for enclosed, shore-power-equipped campers.
Electric heaters like this are straightforward when shore power or an inverter is available. They provide convective heat suitable for short-term use and are low maintenance compared to combustion heaters. Consider available power, run-time, and the requirement that they cannot heat large spaces efficiently without significant electrical supply.
Buying Guide: Choosing The Right Camper Van Night Heater
Heat Type And How It Affects Sleep Comfort
Radiant vs Convective vs Forced-Air: Radiant heaters (propane) warm people and objects directly and are efficient for spot heating during sleep. Convective electric heaters warm air slowly and are quiet but need sufficient power. Forced-air diesel heaters circulate warm air quickly and maintain cabin temperature but require installation.
Power Source And Availability
- Diesel Heaters: Use vehicle fuel or onboard tank; good for off-grid and long-term heating but require wiring, exhaust routing, and fuel management.
- Propane Radiant Heaters: Portable and effective for spot heat; ensure proper ventilation and CO/CO2 monitoring for safety.
- Electric Heaters: Depend on shore power or inverter/battery capacity; simple to use and low maintenance.
Safety Features To Prioritize
- Auto Shutoff: Tip-over and low-oxygen sensors are critical for portable combustion units.
- Exhaust Management: Diesel heaters need secure exhaust routing and heat shields to avoid fumes or burns.
- Carbon Monoxide Monitoring: Any combustion heater used inside a van requires a CO alarm and adequate ventilation.
Installation Complexity
Plug-And-Use: Electric and small radiant propane heaters require minimal setup. Plumb-In: Diesel air heaters need mounting, fuel lines, exhaust piping, and electrical wiring; plan tools, space, and possible professional help.
Noise And Sleep
Consider fan noise for forced-air units. Diesel air heaters often have variable fan speeds—lower speeds reduce noise but lower heat output. Radiant heaters are typically quieter. If light sleep is affected by motor noise, look for units advertising low-noise operation or variable speed controllers.
Size Of Space And Heating Capacity
Match heater output to van interior volume. Diesel units list square-foot ranges; radiant heaters work well in small cabins or for spot-warming areas near the bed. Overpowered units may cycle frequently; underpowered units will struggle to maintain comfortable overnight temperatures.
Altitude And Environmental Considerations
At high elevations, combustion efficiency changes. Some diesel models offer automatic altitude compensation. Propane units may also behave differently above certain altitudes—check manufacturer guidance if you camp in mountainous areas.
Fuel Efficiency And Run Time
Diesel heaters tend to be more fuel-efficient for long overnight use than running an engine. Check fuel tank size and consumption rates to estimate runtime. For electric heaters, calculate battery/inverter capability for desired run hours.
Controls And Convenience
Remote, LCD, and app-based controls allow preheating and temperature scheduling. If you want to warm the van before entering, prioritize models with app or remote start features.
Ventilation And Air Quality
Ensure fresh-air intake and exhaust paths are properly installed. Even indoor-approved portable heaters need monitoring. Consider adding a CO detector and a ventilation plan for safe overnight operation.
Maintenance And Durability
Combustion heaters require periodic cleaning of fuel lines, filters and exhaust passages. Electric heaters need minimal maintenance. Review manufacturer guidance and ensure replacement parts availability.

Comparison Perspectives
- Cost Of Ownership: Diesel heaters have higher installation complexity but lower fuel consumption for extended use. Electric heaters are simpler but may incur battery or generator cost.
- Portability: Propane radiant units are the most portable; built-in diesel units are semi-permanent.
- Safety Tradeoffs: Combustion units offer robust heat but require ventilation and monitoring; electric units avoid combustion risk but need sufficient power.
- Climate Fit: For mild overnight chills, electric or radiant heaters often suffice. For sustained cold or extended off-grid stays, diesel heaters provide continuous cabin heat.
