Things to Watch Out

The primary thing you need to check is the electrical heater size. Say, if you have a compact RV, a big heater is not your need. However, there are small but very mighty heaters that you can turn on and heat up large space. In this case, pay attention not only to size but to power.

Technical Definitions

Speed of heating

Wait till a heater is all done and ready to work is not fun, especially if it lasts for 15-20 mins. Considering climates you’re going to travel through, choose a device that could easily heat up in a few minutes and gives appropriate temperature in no time.

It’s a useful function indeed since it’s simply your safety — once the Fahrenheit reaches a dangerous level, you should not worry about shutting it off at a certain moment.

Here you have two ways: to select the needed temperature or, as mentioned before, just press a button to control the heater. When choosing a device, pay attention to the temperature range it offers.


When it comes to the market, there are gas and electric heaters. There’s one more method to heat up a vehicle — oil furnace, but it’s the least popular and it’s mostly being used as a radiator.  Speaking about a gas heater, it makes use of combustion to maintain heat.

Finally, the heat is being released via the open vent and a blower. Unlike the first type of heaters, electric devices do not require any byproducts. That’s why the majority of auto enthusiasts choose electric heaters for RVs.
