Frequently Asked Questions
What size RV water heater do I need?
Most RVs use 6, 10, or 12 gallon water heaters. Smaller rigs may use 4-gallon models, while larger motorhomes benefit from 10-12 gallon or tankless units that offer continuous hot water.
What’s the difference between tankless and traditional RV water heaters?
Tankless RV water heaters, like the Girard GSWH2, heat water on demand for endless hot water. Traditional units store a limited amount and reheat after depletion.
Which is better: electric or gas RV water heater?
Gas heaters heat quickly and are efficient off-grid, while electric models are quieter and ideal for RV parks with hookups. Dual-fuel models like the Suburban SW6DE offer both.
Can I upgrade to a tankless RV water heater?
Yes, many RVs can be upgraded to tankless models. Look for retrofit-friendly options like the Girard or Fogatti on-demand systems designed for RV use.
Is the Suburban SW6DE a direct replacement model?
Yes, the Suburban SW6DE is a popular 6-gallon gas/electric water heater compatible with many RVs. Always confirm dimensions and wiring before replacing.
What’s the benefit of a 10 or 12 gallon RV water heater?
Larger tanks like the Suburban SW10DE or SW12DEL store more hot water, ideal for families or extended off-grid use without hookups.
Are Girard tankless water heaters good for winter RVing?
Yes, Girard tankless heaters are designed for year-round use, including cold climates. Just ensure your RV has proper insulation and winterization.
Can I install a water heater myself?
If you're comfortable with plumbing and electrical work, it's possible. However, for safety and warranty purposes, professional installation is often recommended.
