Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Heating Power And Space Coverage
- KW/BTU Rating: Higher KW units (7–8 KW) Heat Larger Spaces Faster; 5 KW Units Are Better For Small Vans And Cabins.
- Room Size: Match The Heater Output To The Interior Volume; Manufacturers Often Provide Square-Foot Coverage Estimates.
Fuel Tank And Runtime
- All-In-One Tanks: Units With Built-In Tanks (5–10 L) Offer Portability But May Require More Frequent Refueling.
- External Tanks: Separate tanks allow extended runtime and easier replacement, useful for long trips.
Power Options And Installation
- 12V/24V DC: Standard For Vehicles; check compatibility with vehicle electrical system and alternator capacity.
- AC Support: Some units include 110V/220V adapters for garage or home use—useful for fixed installations or workshop heating.
- All-In-One Vs Remote-Mount: All-in-one units are simpler to install but can generate heat in the same enclosure as the burner; remote-mount designs separate burner and heat exchanger for quieter operation and flexible placement.
Altitude Performance
- Altitude Compensation: If You Operate In Mountains, Choose A Heater With Auto Altitude Compensation Or High Altitude Rating (e.g., 5,000 m / 18,000–20,000 ft).
- Combustion Tuning: Altitude Requires Different Air/Fuel Ratios; Look For Models With Altitude Modules Or Manufacturer Guidance.
Controls And Connectivity
- Remote And Timers: Remote Controls And Timers Allow Preheating; Check Range And Timer Capabilities.
- App/Bluetooth: App Control Adds Convenience For Pre-Start But Verify App Reliability And Compatibility.
- LCD And Diagnostics: Clear Displays And Fault Codes Simplify Troubleshooting And Maintenance.
Fuel Consumption And Efficiency
- Consumption Rates: Compare L/H Or Gal/H Ratings To Estimate Running Costs For Your Typical Use.
- Heat Exchanger Material: Aluminum Exchangers Heat Quickly; watch for claims about reduced exhaust temperature and carbon buildup which affect longevity.
Noise, Venting, And Safety
- Noise Level: All-in-one units may be louder; remote-mount designs often reduce cabin noise.
- Exhaust Routing: Proper Exhaust And Fresh Air Venting Are Critical—install per manufacturer instructions to avoid carbon-monoxide hazards.
- Electrical Load And Fuse Protection: Ensure Vehicle Alternator And Batteries Support The Heater’s Startup Surge And Running Current.
Use Case Comparisons
- Daily Driver Truck/RV: Consider A Reliable 5–8 KW Unit With Altitude Compensation If You Travel Mountains Frequently.
- Overlanding/Portable Needs: Toolbox Or All-In-One With A Handle And Internal Tank Offers Portability; check weight and securing options.
- Garage Or Workshop: Models With AC Support Allow Plug-In Use Without Vehicle Power; ensure indoor ventilation is addressed.
- Cold-Start Engine Preheat: Choose Units Specified For Engine Preheating Or Integrated Water Heating If Engine Protection Is A Priority.
Maintenance And Parts Availability
- Spare Parts: Check Availability Of Pump, Glow Plug, Filters, And Control Boards.
- Serviceability: Models With Diagnostic Displays And Accessible Components Simplify Repairs.
- Manufacturer Support: Look For Clear Installation Guides, Online Tutorials, And Warranty Terms.
Final Selection Tips
- Match Power To Space: Don’t Overspec For Small Vans; Overspecing Can Increase Fuel Use.
- Prioritize Safety: Proper Venting, Electrical Protection, And Mounting Are More Important Than Extra Features.
- Consider Multi-Voltage Units: Dual DC/AC Models Offer Versatility For Both Vehicle And Static Use.
