Buying Guide: Key Considerations For RV Water Heaters
- Tank vs. tankless: Choose a tank model for simple supply and predictable recovery, or a tankless model for endless hot water without storage.
- Capacity and recovery: Higher gallon capacity suits larger households or longer showers; consider recovery time under peak demand.
- Power options: Look for gas, electric, or hybrid heating. Electric elements require shore power or generators; gas models work off propane.
- Durability: Porcelain-lined steel tanks and replaceable anodes extend life; aluminum tanks reduce weight but vary in corrosion resistance.
- Installation space: Check cutout dimensions, available depth, and ducting or venting requirements for gas models.
- Altitude compatibility: Some models are designed to perform better at higher elevations; verify suitability if you travel or camp at altitude.
Frequently Asked Questions
- What size RV water heater should I choose?
– For small RVs or couples, 6-gallon or 10-gallon tanks are common; for families or longer showers, a 10-gallon or tankless option may be better. - Do I need both gas and electric heating?
– Gas heating is effective off-grid; electric heating adds convenience at campsites with power. Hybrid options provide flexibility. - Are tankless RV heaters energy-efficient?
– Yes, they heat water on demand, avoiding standby heat loss, but installation can be more complex and require proper venting. - Which material lasts longer, porcelain-lined steel or aluminum tanks?
– Porcelain-lined steel tends to resist corrosion longer with proper anode protection; aluminum tanks are lighter and low-maintenance but may have different longevity profiles. - Can I upgrade my RV heater easily?
– Many units are designed for standard cutouts and provide installation guides; check compatibility with your RV’s existing system and space. - What maintenance is needed?
– For tank heaters, inspect and replace anode rods as part of routine maintenance; tankless units may require periodic venting and cleaning per manufacturer guidance.
