RV 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.

Which Diesel Heating Capacity Is Right For Me?

Heating capacity is key when choosing a built-in diesel heater. Smaller caravans up to 24 feet only require a heater with a 2 kW output, which provides efficient warmth while avoiding carbon build up due to running at high power.

For medium to large caravans over 24 feet, heaters in the 4–6 kW range offer the best performance needed to evenly heat larger interiors, even in colder climates. Avoid choosing a heater in this range for smaller caravans, as the high output can overheat the space. These units operate at lower output due to their size and consume less fuel making them more energy efficient. They do need to run on high output occasionally to minimise carbon build up over time.

Choose A Quiet Diesel Heater.

Modern diesel heaters incorporate noise reduction features. Look for models that 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. To get uninterrupted rest while travelling in colder areas, a quiet heater is a non negotiable. Noise reduction features are mostly prioritised in premium models such as the Webasto Air Top Series 2000STC and high output 4kw to 6kw models.

Heater 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 only a small amount of diesel per hour, allowing you to extend your trips without frequent refuelling. Some heating systems include advanced sensors and automatic climate control for even heat distribution, optimising fuel consumption based on your heat settings.

Diesel Heater Safety Features

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.
