How to Choose the Best RV Water Heaters, Pumps & Accessories

Understanding RV Water Heater Types

RV water heaters generally fall into two main categories: tank and tankless models. Tank models store a certain amount of hot water, typically 6-12 gallons, and reheat it as needed. They offer a readily available supply but can run out during high demand. Tankless heaters, on the other hand, heat water on demand, providing an endless supply as long as the fuel source is active. They are more energy-efficient but may have a slightly longer wait time for the first burst of hot water.

Key Features to Consider

  • Fuel Source: Many RV water heaters run on propane, electricity, or a combination of both (dual-fuel). Propane is common for off-grid use, while electric is convenient when hooked up to shore power. Dual-fuel models offer the most flexibility.
  • Capacity/Flow Rate: For tank models, consider the gallon capacity. For tankless, look at the Gallons Per Minute (GPM) flow rate, ensuring it meets your needs for showering and other tasks.
  • Ignition Type: Electronic ignition is standard on most modern units, offering convenience and reliability.
  • Durability and Installation: Choose units made with corrosion-resistant materials for longevity. Ensure the dimensions fit your RV's designated space and consider the complexity of installation.

Essential RV Water Pump Considerations

The water pump is the heart of your RV's plumbing system, delivering fresh water from the tank to your fixtures. Look for pumps with sufficient GPM to provide adequate pressure for showers and faucets. Diaphragm pumps are common and generally reliable. Consider noise levels, as some pumps can be quite loud. Self-priming capabilities are also a valuable feature, ensuring the pump can easily start even if it loses its prime.

Frequently Asked Questions

How often should I flush my RV water heater?
It's recommended to flush your RV water heater at least once a year, or more frequently if you notice sediment buildup or reduced performance. This process removes mineral deposits and sediment that can affect efficiency and longevity.
What is the difference between an RV water heater and a home water heater?
RV water heaters are designed for mobile use, typically running on propane or 12V electricity, and are much more compact. Home water heaters are larger, usually powered by natural gas or 240V electricity, and are stationary.
Can I use a tankless water heater in my RV?
Yes, tankless water heaters are an increasingly popular option for RVs. They offer an endless supply of hot water and are often more energy-efficient than traditional tank models, though they may have a slightly higher initial cost.
How do I winterize my RV water heater?
Winterizing involves draining the water heater completely and then blowing compressed air through the lines to remove all residual water. You may also need to add RV-specific antifreeze to prevent freezing and damage.
What causes my RV water pump to run constantly?
A constantly running water pump can indicate a leak in your plumbing system, a faulty check valve, or a malfunctioning pressure switch. Inspect all fixtures and connections for drips and ensure the pump's pressure settings are correct.
