Caravan Hot Water System Capacity
Selecting the right capacity for your caravan's hot water system is essential to ensure you have enough hot water for your needs without wasting energy or space. Consider the following factors:
- Number of occupants: More people generally require a larger capacity system.
- Usage patterns: Consider how often and for how long you use hot water during your camping trips.

As a general guide:
- Small caravans (1-2 people): 10-15 liter capacity
- Medium caravans (2-4 people): 15-25 liter capacity
- Large caravans or motorhomes (4+ people): 25+ liter capacity
For those who prefer an instant hot water system for their caravan, the capacity is measured in liters per minute rather than tank size. These hot water systems can provide a continuous flow of hot water as long as there's a water and power supply.
Caravan Hot Water System Energy Efficiency
Energy efficiency is a key consideration when choosing a hot water system for your caravan. In Australia, appliances are rated using the Energy Rating Label system, which helps consumers compare the energy efficiency of different products.
The importance of energy efficiency in caravan hot water systems:
