A portable hot water system is one of the most valuable upgrades you can add to a camper trailer, especially when camping with family. Being able to shower properly makes longer trips, cold weather, and camping with kids far more comfortable.
This guide focuses on portable gas hot water systems that work well for camper trailers in Australia, not gimmicks or overcomplicated setups.

What Matters Most for Camper Trailers
When choosing a system, prioritise:
- Stable water temperature
- Ability to handle back-to-back showers
- Compatibility with jerry cans or buckets
- Gas efficiency
- Safety shut-offs
For families, consistency and simplicity matter more than raw power.
Best Overall for Families
The Companion AquaCube is one of the most popular family options. It includes a built-in pump, good temperature control, and handles multiple showers without big temperature swings. It’s heavier and more expensive, but very reliable.
Best for Simple, Fast Setup
The Joolca HOTTAP range is excellent if you want quick setup and easy packing. These units work well with jerry cans and are popular with families who camp regularly but don’t want a permanently plumbed system.
Best Budget Option
Budget units like the Gasmate Odyssey still do the job for occasional trips. They require a bit more attention to setup and water flow but are perfectly usable for family camping if managed properly.
Are Portable Hot Water Systems Worth It?
If you camp with kids more than a few times a year, a portable hot water system is absolutely worth it. It reduces stress, saves time, and makes camping more enjoyable for everyone.
Verdict:
For camper trailers, a portable gas hot water system is one of the highest-value comfort upgrades you can buy.
