Prioritize models with at least 8KW for versatile use across seasons and vehicle types.
Fuel Efficiency and Capacity
Fuel efficiency affects how often you need to refill. Units consuming 0.16 to 0.62 liters per hour are efficient. Look for tanks of at least 7.5 liters for long trips to avoid interruptions during overnight use.
Check both consumption rate and tank size to balance cost and convenience.
Altitude Compensation
Altitude compensation adjusts the combustion process for high elevations. Some units work up to 18000 feet ensuring consistent heat at mountain passes. Without this, heaters may struggle to maintain output in thin air.
Ensure the heater supports your max elevation range for reliability.
Control Options
Control options include LCD screens remotes and smartphone apps. Bluetooth allows preheating from a distance while remotes offer convenience without connectivity. Some models include indoor temperature sensors for accurate regulation.
