How To Choose The Best Heater For RV Boondocking?
Energy Source & Runtime
Boondocking is literally off-the-grid RV travel, where you will camp without any hookups outside developed campgrounds for days to weeks.
So, when choosing the best heater for RV boondocking, energy source and runtime are the two most important elements to consider. It must be able to run independently of landing power or electrical hookups, and besides, work efficiently.
Energy Source
Out of different options, propane heaters are the shiniest contender for energy efficiency.
It is cheaper than diesel whilst consuming less fuel to produce the same amount of heat as gasoline, so it usually has a smaller tank size and the whole generator design is more compact.
It also only requires very little electricity to run the fan, which you can hook up to your RV battery.
A dual-fuel heater is another possible option as it commonly comes with propane adapters. When the unit runs out of juice, you can refill it from your vehicle.
Runtime
As stated above, propane lasts longer than gasoline.
But you should also determine how long your RV boondocking travel usually lasts: several days or several weeks? What’s the weather like during your trip? And, how often do you use the heater?
For longer trips during cold months, you’ll have to use the heater more frequently, therefore, the fuel tank must obviously be larger.
On the market, the runtime of the RV boondocking heater ranges from 5 hours to 200 hours.
Heating Capability
A heater’s heating capacity is measured in BTUs (British Thermal Units), and conventionally every 10,000 BTU can raise 1-quart water’s temperature by 1 degree.
The heating requirements are different between RVs, depending on the weather condition, the number of people inside the vehicle, the RV interior area, and how insulated the RV is. The heating capability of RV heaters is vast, commonly ranging from 2000 to 20,000 BTU.
If you’re a non-experience buyer, choosing a model with adjustable heating capability is better for you.
Safety Features
No matter the fuel type that you’re choosing to run an RV heater, safety is always a top priority! Both traditional and modern RV heaters share these safety features in common:
Auto-shutoff switches when tipping over or running out of fuel
Oxygen sensors, which can detect and measure the oxygen volume inside your RV. Once the sensor finds the oxygen volume drops below a certain level, the unit will automatically turn off or send sound alerts to you.
Besides, modern heaters are equipped with auto-adjust thermostats.
