Exploring our amazing country in your caravan or camper should be relaxing and pleasurable without having to give up the luxuries of home, like taking a hot shower. There are a variety of RV water heaters available but if you want the flexibility to free camp you’ll most likely need a gas-heated model. Water storage heaters (made by Suburban, Whale & Truma) keep a tank of hot water at a preset temperature ready for the instant you need it. Some brands offer gas only or gas/electric models which allow you to save LPG when connected to mains power. Instantaneous water heaters like the Challenger califont series are gas-powered and operate on demand. This means the water heats up as it flows through the califont. For 230V only water heaters see the Isotemp models - these are more suitable for marine use and are sometimes found in the campervan rental fleet.
