Diesel Caravan Heater Info

If you're installing the heater yourself, we have an FAQ page on AU Focus heaters, one of the most reliable and price conscious options. Additionally shop through our range of installation kits in our spare parts range or if you're looking to increase fuel capacity, we stock various fuel tanks from 5L to 12L to ensure maximum warmth during your trip around Australia.

Whether you’re doing a big lap around Australia's outback or camping by the coast in winter, the right diesel heater will make a difference.

Why Choose A Diesel Heater For Your Caravan?

The 5 most common reasons most caravan owners choose a diesel heater are:

  • Consistent, powerful warmth in any season.
  • Compact, space-saving installation.
  • Low energy draw, ideal for 12V systems.
  • Safe, clean combustion with minimal maintenance.
  • Affordable heating units available.

How Much Do Caravan Heaters Cost?

Caravan heaters can cost as low as $300 for cheap models and upwards of +$3000 for premium models. Heating capacity also plays a role in costs and is key factor when choosing a built-in caravan heater. As rule of thumb we recommend:

Caravan Heaters For Up To 24 Feet:

Between $650 to over $1,000 depending on the brand and features.

Caravan Heaters For Over 24 Feet:

Prices start from approx. $1,500 to $3,000.

Heaters in the 4–6 kW range offer the best performance needed to evenly heat larger interiors, even in colder climates. However, most quality made2kW units are sufficient for most caravans.

Avoid choosing a heater in this range for smaller caravans, as the high output can overheat the space.

Are Caravan Diesel Heaters Noisy?

Yes, they can be if you choose a cheaply made unit and if not installed correctly. Quality made caravan heaters incorporate noise reduction into their design and features.

Modern caravan heaters incorporate noise reduction features which include silent fuel pumps, insulated ducts, and smart fan controls to minimise disruptions at night. Minimising noise levels is essential for sleeping in small caravans where the heater is typically installed in close proximity to sleeping areas.

Noise reduction features are mostly prioritised in premium models such as the Webasto Air Top Series 2000STC and high output 4kw to 6kw models.

Fuel Efficiency For Longer Operation.

Built in diesel heaters are known for their low fuel consumption, making them ideal for off grid adventures. Most units use a small amount of diesel per hour, allowing you to extend your trips without frequent refuelling.

  • AU Focus 12V 2KW Diesel Heater With Bluetooth Includes Tank Fuel Consumption (L/h): 0.1-0.3

Are Diesel Heaters Safe For Caravans?

Yes, diesel heaters are safe for caravans when properly installed. RV diesel heaters are engineered for both safety and performance. They operate with sealed combustion chambers, which expel exhaust fumes outside to minimise carbon monoxide.

Modern heating systems also come with automatic shut off features, overheating protection and frost protection modes designed to improve operating safety.

Always consult with an experienced professional with installation, to ensure the heating unit is installed up to Australian standards.
