Buying Guide: How To Choose A Diesel Night Heater
Heat Output And Coverage
Match heater kW output to the volume you need to warm. Smaller vans and cabins typically require 2–5 kW, while larger motorhomes, garages, or well-insulated spaces may need 5–8 kW or multiple units. Manufacturers often list an indicative square-foot coverage; use that as a baseline but account for insulation and outside temperatures.
Fuel Consumption And Runtime
Look at reported fuel burn rates (gallons or liters per hour) and tank capacity to estimate runtime. Lower consumption extends overnight operation on limited tank sizes. Consider whether you want a built-in tank or an external fuel feed for longer periods.
Power Compatibility
Confirm whether the unit supports 12V, 24V, or AC power. Vehicles commonly use 12V; heavy trucks and some setups use 24V. AC-capable or transformer-included heaters enable garage or home use without vehicle battery dependency.
Altitude Performance
If you operate at elevation, automatic altitude compensation or altitude-capable settings maintain combustion efficiency. Check rated maximum altitude—some units are specified to 18,000–20,000 ft.
Controls And Connectivity
Options include onboard LCDs, IR remotes, and Bluetooth app control. Remote or app control enables preheating and easier temperature management when sleeping or outside the vehicle.
Noise And Vibration
Noise levels vary with pump design and insulation. Look for low-vibration pumps or models that advertise reduced noise if quiet overnight operation is important.
Safety Features
Key features include CO detection/alarms, overheat protection, leak-proof tank caps, and low-fuel or fuel-level indicators. For indoor or sleeping-area use, a CO alarm and proper ventilation are essential.
Installation And Portability
Decide between all-in-one portable units (no installation required) and systems needing hard installation (better integration but more work). Portable toolbox designs are helpful for shared use across vehicles or for temporary setups.
Maintenance And Serviceability
Consider ease of access to the combustion chamber, fuel pump, and filters for periodic maintenance. Replacement parts availability and clear installation manuals or tutorials are practical advantages.
Use Case Comparisons
- Short Overnight Use In Camper: Portable all-in-one with built-in tank and app/remote control.
- Permanent Vehicle Install: Hardwired unit with external fuel feed and altitude compensation.
- Garage Or Shop: AC-capable heater with higher BTU ratings and overheat protection.
- High-Altitude Travel: Units with automatic altitude adjustment rated for >10,000 ft.
Final Selection Tips
Prioritize safety features and correct power compatibility first. Match kW to volume and choose a model with control options that fit your routine (app, remote, or manual). For multi-purpose use, consider models with AC support and portable configurations.
