Finding a reliable hot water heater is crucial for comfortable RV living. While purchasing a brand-new unit is an option, exploring the used market offers significant cost savings. This guide dives deep into everything you need to know about buying and maintaining used RV hot water heaters, helping you make an informed decision.
What are the Different Types of RV Hot Water Heaters?
RV hot water heaters primarily fall into two categories: gas and electric. Gas water heaters are common due to their independence from shore power, utilizing propane or LP gas for heating. Electric water heaters, on the other hand, require hookup to an external power source (120V AC). Understanding these differences is vital when selecting a used unit. You'll need to consider your typical camping style and available power sources. Some RVs even feature combination gas/electric units, offering flexibility.
How Much Does a Used RV Hot Water Heater Cost?
The cost of a used RV hot water heater varies greatly depending on several factors: the brand, size (typically measured in gallons), age, condition, and where you purchase it (private seller, RV salvage yard, online marketplace). You can often find significant discounts compared to new units, sometimes saving hundreds of dollars. However, always remember that a lower price tag might mean higher maintenance or repair costs down the line.
Where Can I Find Used RV Hot Water Heaters?
Several avenues exist for finding a used RV hot water heater:
- Online Marketplaces: Sites like eBay, Craigslist, and Facebook Marketplace often list used RV parts, including water heaters. Thoroughly examine the listings for details about the unit's condition and any known issues.
- RV Salvage Yards: These specialized yards often have a wide selection of used RV components, often at competitive prices. You can inspect the units before purchasing, which is a significant advantage.
- RV Dealerships: Some dealerships may accept trade-ins or have used parts available. While prices might be slightly higher, you might get some warranty or guarantee.
- Private Sellers: Check forums and online RV communities for individuals selling used parts from their RVs.
What Should I Look For When Buying a Used RV Hot Water Heater?
Inspecting a used RV hot water heater thoroughly before buying is paramount. Here’s what to look for:
- Leaks: Check carefully for any signs of leaks around the tank, fittings, and valves. Even a small leak can lead to significant problems.
- Rust and Corrosion: Examine the exterior for rust or corrosion, which can indicate internal damage. Significant rust is a major red flag.
- Anodes: Check the anode rod. This sacrificial rod protects the tank from corrosion; a severely corroded anode rod suggests the tank might be nearing the end of its life.
- Burner (for Gas Units): Inspect the burner for cleanliness and any signs of damage. A clogged or damaged burner can lead to inefficient heating or safety hazards.
- Heating Elements (for Electric Units): If it's an electric unit, check the heating elements for damage.
- Pressure Relief Valve: Ensure the pressure relief valve is functioning correctly. This safety feature prevents pressure buildup that could lead to tank rupture.
How Long Do Used RV Hot Water Heaters Typically Last?
The lifespan of an RV hot water heater, whether new or used, depends heavily on usage, maintenance, and water quality. A well-maintained unit can last for 8-10 years or even longer, but neglecting maintenance can shorten its life considerably. A used heater may have already consumed a portion of its lifespan.
How Can I Extend the Life of a Used RV Hot Water Heater?
Proper maintenance is key to extending the life of your used RV water heater. This includes:
- Flushing the Tank: Regularly flushing the tank removes sediment buildup, which can reduce efficiency and damage the heating elements.
- Replacing the Anode Rod: Periodically replacing the anode rod helps protect the tank from corrosion.
- Inspecting for Leaks: Regularly inspect for leaks and address them promptly.
- Proper Venting: Ensure proper ventilation for gas water heaters to prevent carbon monoxide buildup.
What are the Common Problems with Used RV Hot Water Heaters?
Common problems include leaks, burner issues (gas units), faulty heating elements (electric units), and corrosion. Thorough inspection before purchase is critical to avoid unexpected repairs.
By carefully considering these points and performing a thorough inspection, you can increase your chances of finding a reliable used RV hot water heater at a fraction of the cost of a new one, ensuring hot showers on your next adventure. Remember, a little due diligence can save you a lot of money and headaches in the long run.
