Choosing the right electric water heater for your campervan involves balancing several critical factors including power requirements, available space, hot water needs, and budget. I've tested numerous setups and learned that the perfect heater depends entirely on your specific van layout and lifestyle.
Before making your final decision, consider your typical usage patterns—do you need hot water for quick hand washing or long showers? How many people will be using the system? Will you primarily have access to shore power or rely on batteries and generators? These questions will guide you toward the right type and size of water heater.
Power requirements are arguably the most critical factor when choosing an electric water heater for your campervan. Most electric heaters require either 110V AC power or substantial DC battery capacity, which significantly impacts your van's electrical system design and costs.
For 110V tank heaters like the Feelrogast 8 Gallon or Bosch 2.5 Gallon, you'll need either regular shore power access or a large inverter system (2000W+) with sufficient battery bank to support the heating load. These heaters typically draw 12-15 amps during operation, which can quickly drain batteries if used extensively off-grid.
If you're planning to use a generator as your primary power source, ensure it can handle the starting surge of water heater elements. A 2000-watt generator is typically sufficient for most electric water heaters, but consider a larger unit if you'll be running other appliances simultaneously.
⏰ Critical Power Note: Most electric water heaters require dedicated 20-amp circuits with appropriate wiring. Never attempt to power high-wattage heaters from standard 15-amp circuits or extension cords designed for low-power devices.
12V electric options are extremely limited in the market due to the physics of water heating—most 12V systems simply can't generate enough power to heat water effectively for van use. This is why many van lifers opt for propane tankless systems like the FOGATTI or Ranein models, which run on 12V control systems but use propane for the actual heating.
The decision between tank and tankless water heaters impacts everything from installation complexity to daily usage patterns. Tank heaters store and maintain a reservoir of hot water, providing immediate access but consuming energy continuously to maintain temperature. Tankless systems heat water on demand, eliminating standby energy loss but requiring more power during operation.
| Feature | Tank Heaters | Tankless Heaters |
|---|---|---|
| Hot Water Availability | Immediate, limited by tank size | Unlimited, slight delay for heating |
| Energy Efficiency | Lower (standby losses) | Higher (no standby losses) |
| Power Requirements | Lower continuous draw | Higher instantaneous draw |
| Installation Complexity | Moderate | Higher (venting, gas lines) |
| Maintenance Needs | Anode rod replacement | Descaling, filter cleaning |
For van lifers with limited electrical capacity, tankless propane systems often make more sense despite the more complex installation. The ability to have unlimited hot water without draining batteries is invaluable for extended off-grid trips. However, if you have reliable shore power or a robust solar system, electric tank heaters provide simplicity and reliability.
Campervan space constraints demand careful planning when installing water heaters. Measure your available space precisely, accounting for not just the unit itself but also required clearances for ventilation, maintenance access, and plumbing connections.
Mini-tank heaters like the Nessxa 1.8 Gallon or BISELONG 2.5 Gallon are ideal for space-constrained installations, fitting easily under sinks or in small cabinets. These units work best as point-of-use solutions for specific fixtures rather than whole-van systems.
For larger installations, consider the weight distribution in your van. Water heaters filled with water can add significant weight (8 gallons = 67 pounds), so position them low and centered to maintain proper vehicle balance. The Ariston 8 Gallon and Feelrogast 8 Gallon both weigh around 30 pounds empty, so plan accordingly.
Installation difficulty varies significantly by model. Electric tank heaters with standard plumbing connections are generally DIY-friendly, while propane tankless systems may require professional installation due to gas line requirements and venting needs. Always check local regulations and manufacturer guidelines before attempting installation.
BTU (British Thermal Unit): The amount of energy required to raise one pound of water by one degree Fahrenheit. Higher BTU ratings mean faster heating but also greater power consumption.
Water heater prices range from under $60 for basic models like the ECOTINYMACH Tankless to over $400 for premium systems like the Ranein 65,000 BTU. However, initial cost is only part of the equation—consider ongoing energy costs, maintenance requirements, and expected lifespan when calculating true value.
Budget-friendly options like the BISELONG 2.5 Gallon ($99.98) provide adequate performance for basic needs but may have shorter lifespans and higher failure rates. Premium models like the Bosch 2.5 Gallon ($209.73) offer better reliability and longer warranties but require higher initial investment.
For propane systems, factor in the cost of propane tanks and refills when calculating long-term operating expenses. While propane tankless heaters have higher upfront costs, they often provide better value for heavy users due to lower operational costs compared to electric systems that drain batteries or require generator fuel.
Proper installation is critical for both performance and safety. Electric water heaters require appropriate electrical wiring, circuit protection, and ground fault protection. Most 110V heaters need dedicated 20-amp circuits with 12-gauge wiring minimum.
Plumbing considerations include selecting appropriate materials for your van's water system. PVC and CPVC pipes are common choices, but ensure your fittings are compatible with both hot water temperatures and the specific heater model you choose.
For propane tankless systems, professional installation is strongly recommended due to the complexity of gas line installation, venting requirements, and safety considerations. These systems require proper combustion air intake and exhaust venting to prevent carbon monoxide buildup in your living space.
