Ultimate Guide to the Best Diesel Caravan Heater Australia!

The most important factor to take into account while trying to heat or cool an area is its size. Additionally, rather of fumbling with complex calculations for cubic capacity, you may use the length of the vehicle as a basic size guideline for a diesel heater because most trailers are approximately 2.2 meters wide.

In Australia, the three most common heater sizes are 2kW, 2.2kW, and 5kW. The heater will obviously need to be more powerful to heat the space effectively the longer your trailer.

Choosing the right heater for your automobile is essential. A heater that is too tiny could find it difficult to heat the space, and since it is exerting so much effort, it might create some noise. Huge heaters may either struggle to maintain the desired temperature and run at a very low volume, which can result in carbon buildup and more maintenance, or they may often cycle on and off.

These diesel heater sizes are suggested based on the length of your caravan.

If we say 2kw diesel heaters for caravans vs 5kw diesel heater for caravan, Diesel heater size based on caravan length:

Diesel Heater Size

ü  2kW

ü  2.2kW

ü  5kW

Caravan Length

ü  Up to 21 feet

ü  21 to 24 feet

ü  24 feet +

The caravan length in Australia is 19 feet, so you might go for 2kW diesel heater. In case, your caravan is flat floor camper, pop up or having lots of canvas, you should select 2.2kW heater instead as the heat will be gone faster.

Sometimes guides will show up the heater’s output range as 850kW/2000kW instead of flat and simple numbers like 5kW or 2kW. If the situation comes in that’s way for selecting diesel heater, go for the second number on the range which shows maximum output of heater.

The heater’s weight and size are unimportant, but you must consider where to place it in the caravan based on the available space. Even if a large heater has excellent evaluations and the right kW capacity for your car, it won’t help you if you don’t have the space for it. 5kW heaters are larger than 2kW heaters, as one might anticipate.

Diesel heaters may be placed almost anywhere in a caravan, but since they need to be connected to the fuel tank, it’s best to put them up front if at all feasible.

The 5kW diesel heater is ideal for bigger caravans and vans with canvas, which will let the heat out more quickly, when choosing between a 2kW and a 5kW diesel heater for a camper or caravan. The 2kW will work well and be simpler to provide a consistent heat in smaller vehicles. Keep in mind that the 2kW will frequently operated at full power, which will increase noise levels and fuel consumption. You will need to periodically run the 5kW on high to burn off any carbon build-up because it will be operated mostly on low.

The 5kW camper heater makes the place cozy and heat up pretty quickly. Which may be more than enough is smaller vans unless you need it in freezing temperature or have a space to allow escaping un-wanted heat.
