Buying a used RV hot water heater can be a smart way to save money, but it's crucial to approach the purchase with caution and knowledge. This guide will help you navigate the process, from understanding different types to identifying potential problems and ensuring a successful installation.
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 the most common, offering independent operation regardless of campground hookups. Electric water heaters are more energy-efficient when plugged into shore power but require electricity to function. Some RVs even feature hybrid systems combining both gas and electric heating elements. Understanding the type you're considering is critical for proper installation and maintenance.
What should I look for when buying a used RV hot water heater?
This is a key consideration. When inspecting a used RV hot water heater, thoroughly check for any signs of damage, rust, or leaks. Examine the anode rod (if present), a sacrificial rod that protects the tank's interior from corrosion. A severely corroded anode rod indicates significant internal tank deterioration, potentially leading to leaks and costly repairs down the line. Look for dents or other physical damage that could compromise the tank's integrity. Testing the heating element (gas or electric) is also crucial to confirm its functionality. If possible, try turning it on to check for proper heating and the absence of unusual noises.
How much does a used RV hot water heater cost?
The cost of a used RV hot water heater varies greatly depending on size, type, condition, and the seller. You can expect to find prices significantly lower than new models, sometimes saving hundreds of dollars. However, remember that lower cost often correlates with increased risk of repairs or replacement down the line. Consider balancing cost savings with the potential for future expenses. Carefully weigh the pros and cons to determine if the potential savings justifies the risk.
How long does an RV hot water heater last?
The lifespan of an RV hot water heater depends heavily on usage, maintenance, and water quality. Under ideal conditions and with regular maintenance, you might expect a lifespan of 8-10 years. However, factors like hard water and infrequent draining can significantly shorten this lifespan. Corrosion and leaks are the most common causes of failure. Regular flushing and anode rod replacement can extend its life considerably.
Where can I buy a used RV hot water heater?
You can find used RV hot water heaters in several places, including online marketplaces (like eBay or Craigslist), RV salvage yards, and even directly from RV owners upgrading their systems. Always inspect the unit thoroughly before purchase, and be wary of deals that seem too good to be true. Consider getting a professional assessment if you're unsure about the condition.
How do I install a used RV hot water heater?
Installing a used RV hot water heater is similar to installing a new one, but it requires extra care and attention to detail. Ensure you have all the necessary connections and fittings before beginning. Consult the manufacturer's manual (if available) for specific instructions. Pay close attention to gas connections (if applicable) as improper connections can lead to serious hazards. It’s strongly recommended to have a qualified technician handle the installation, especially if you lack experience with RV systems. Remember safety is paramount!
What are the common problems with used RV hot water heaters?
Common problems with used RV hot water heaters include leaks (often due to corrosion or tank damage), faulty heating elements (gas or electric), and malfunctioning thermostats. Corrosion of the anode rod is a frequent indicator of potential internal tank damage. A build-up of sediment at the bottom of the tank can also reduce efficiency and lead to premature failure. Regular maintenance, including flushing and anode rod replacement, can help mitigate many of these issues.
This comprehensive guide provides a starting point for anyone considering a used RV hot water heater. Remember to prioritize thorough inspection and potentially professional installation for a safe and trouble-free experience. By following these tips, you can significantly increase your chances of finding a reliable and cost-effective solution for your RV's hot water needs.
