Used in Buyers Guides to list key buying criteria at a glance. Each item gets an auto-generated checkbox icon via CSS.
- Heat output (kW): 2kW suits most caravans up to 7m. Larger vans or very cold conditions may need 4kW.
- Fuel consumption: Look for 0.1–0.25L/hr. Lower is better for off-grid travel.
- Power draw: 10–30W at running speed. Check startup draw too, as some spike to 80W+.
- Noise level: Cheap units can be noisy. Look for reviews mentioning noise at low settings.
- Altitude compensation: Essential if you’re travelling to high areas. Premium brands adjust automatically.
- Brand support in Australia: Can you get parts and service on the road? This matters more than price.

7. Tip Box
For helpful advice, shortcuts, or insider knowledge. Use 1-2 per blog maximum.
Run your diesel heater for at least 15 minutes every 2–3 weeks, even in summer. This prevents carbon buildup, which is the most common cause of reliability issues.
8. Warning Box
For safety info, legal requirements, or critical gotchas. Only when genuinely important.
Never use an unflued gas heater inside your caravan overnight. Carbon monoxide poisoning is a real and serious risk. A diesel heater is the safest way to heat your van while sleeping.
9. Key Takeaway Box
Used at the end of major sections or as a blog summary. Works with either a list or a paragraph. The label can be “Key Takeaway”, “Bottom Line”, or “Final Takeaway”.
With a list:
- A diesel heater is essential if your Big Lap includes cold-weather regions
- The Autoterm Air 2D is the safest choice for most travellers
- The Belief Air Pro 2kW is the best value if budget is tight
- Don’t cheap out on installation; do it right or pay a professional
With a paragraph:
If your Big Lap includes anything south of Brisbane in winter, a diesel heater isn’t optional. Spend the money on a reputable brand, get it installed properly, and you’ll wonder how you ever travelled without one.
10. Read More (Single Link)
The primary way to interlink content. The label text can be customised (e.g. “Read More”, “New to Solar?”, “Related Guide”).
With a custom label:
11. Read More (Multiple Links)
