RV heaters or camping heaters will keep you nice and warm, when the sun goes down. Well, but that's obvious isn't it. But how to choose the right camping heater is another story.
It really depends upon where you usually go camping, how often and most important, the climate conditions on your travel route. I guess that if you live in a warmer climate you don't need a heater, do you? Or you might just need one on occasionally, lets say during a night sleeping in the desert.
Anyway, you can choose between the portable heaters and build in heaters. And that fact boils down to;
The inexpensive electrical powered heaters are more or less regular household heaters that will work if you are on a AC/DC hook up and will provide convenient heat.
Great if you stay in a camping site, but that's just about it.
The next best camping heater are the portable radiant heaters. They radiate heat in waves to the object they hit and bounce it back. Just like the sun does.
These heaters come in various sizes and can also be used in your apartment, house, garage or any other place you can think of.
Most of them operate on propane cartridges and some of them can be even coupled up to a regular propane bottle via a quick coupler. They will not drain your battery, because they don't have a fan to blow the heat around, therefore they don't need electrical power.
One thing to keep in mind, is that these heaters don't have a thermostat. They may have two, three or more temperature settings, but that's as far as it goes. So you'll probably need to open up the vent and a window a little bit in order to avoid condensation when it gets to toasty.
That way you will have an efficient heater with you and the only thing you have to think about is the leaking gas. But don't worry about it so much, because most of the models have an auto shut-off switch build in them in case of a tip over or even a lower oxygen level.
And a carbon monoxide warning system is something you should always have on board your camper anyway.
Larger portable units use the same operating system, but without the cartridges.
They can be mounted on a wall or as a free standing heater mounted on a feet kit anywhere you need them. Again, beside being used in RV's a lot of people also use them at their homes to cut down the heating bills.
Apparently their high fuel efficiency is able to tackle the house heating bills. Read the reviews in the Amazon search box below, do your math and see what you can come up with.
The larger the heater, the larger the area that can be heated. That's why the portable radiant heaters come in various sizes. The small ones will more then sufficiently heat up a tent, while the larger ones take care of larger motor-homes, trailers and apparently even a part of your house if you wish so.
A built in RV heater or furnace is a totally different unit to say so. First of all, this is a permanently build in heater, which has a blowing fan and a thermostat located wherever you want it to be. These quite compact units operate mostly on propane gas or your vehicles fuel.
In order for the fan to work properly it of course needs to be connected to the auxiliary battery. The power drain will depend on the power setting and the fan. Various options are available in different countries so check around and see which heater does the best job for you.
Cabin heaters such as the Webasto and Eberspacher use regular or diesel fuel. It can be either pumped up from your vehicles fuel tank or you can use a separate tank or canister for that type of fuel.
Both options are of course being updated on regular bases in terms of fuel and power efficiency. These units will draw anything from below 1Ah to just below 3Ah from your auxiliary battery.
It all depends on the thermostat settings and keep in mind the fact, that the battery power at cold weather camping can drop up to 30%. It's virtually impossible to do the math and get it right. To make a long story short, I get almost two nights of heating for my diesel powered Eberspacher on my leisure (auxiliary) battery.
