Your Guide to an Endless Hot Water RV Adventure
Why an Electric Tankless Water Heater is a Game-Changer for Your RV
Tired of lukewarm showers halfway through your camping trip? An electric tankless water heater, also known as an on-demand water heater, can be a fantastic upgrade for your RV. It heats water only when you need it, meaning you won’t run out of hot water in the middle of a rinse cycle. This guide will help you pick the best one for your adventures.
Key Features to Look For
1. Flow Rate
This tells you how much hot water the heater can produce at once. For an RV, a flow rate of 1.0 to 2.0 gallons per minute (GPM) is usually enough for one shower or faucet. If you have multiple people or appliances needing hot water at the same time, you’ll need a higher GPM.
2. Power Requirements (Amperage and Voltage)
Electric tankless heaters need a lot of power. Check your RV’s electrical system. Many require a 30-amp or 50-amp service. Make sure your RV can handle the power draw. Some might need two separate circuits.
3. Temperature Control
Look for models with precise temperature control. This lets you set the exact temperature you want for your shower or dishes. Digital displays make this easy.
4. Size and Weight
RV space is precious. Tankless heaters are much smaller than traditional tank heaters. Check the dimensions and weight to ensure it fits your RV’s storage or installation area.
5. Energy Efficiency
These heaters are generally more efficient because they don’t waste energy keeping a tank of water hot. Look for ENERGY STAR certified models if available.
Important Materials and Quality Indicators
1. Heating Elements
Most electric tankless heaters use durable stainless steel heating elements. This material resists corrosion and lasts a long time. Higher quality models use thicker gauge stainless steel.
2. Casing and Build Quality
The outer casing should be sturdy and made from durable materials like high-grade plastic or metal. Check for good seals and a solid feel. This protects the internal components from moisture and vibration common in RV travel.
3. Wiring and Connections
Ensure the wiring is properly insulated and connections are secure. Poor wiring can be a safety hazard and reduce the heater’s lifespan.
Factors That Improve or Reduce Quality
Factors That Improve Quality:
- Brand Reputation: Stick with well-known brands that have good reviews and offer solid warranties.
- Customer Support: A company that offers good customer service and readily available parts is a big plus.
- Safety Features: Look for overheating protection, dry-run protection, and anti-freeze features.
Factors That Reduce Quality:
- Cheap Materials: Using flimsy plastic or thin metal can lead to early failure.
- Poor Insulation: This can make the unit less efficient and potentially unsafe.
- Lack of Safety Features: Missing essential safety functions puts your RV and your safety at risk.
User Experience and Use Cases
RV owners love the endless hot water! Imagine taking a long, hot shower after a day of hiking. Or washing a pile of dishes without worrying about running out. These heaters are great for full-time RVers, families, or anyone who enjoys extended trips. They are also quieter than propane models. Installation can be a DIY project for some, but it might require professional help if you’re not comfortable with electrical work.
Frequently Asked Questions (FAQ)
Q: How much electricity does an electric tankless water heater use in an RV?
A: They use a significant amount of electricity, often requiring a 30-amp or 50-amp RV service. Always check the specific model’s power needs.
Q: Can I run an electric tankless water heater on a standard campsite electrical hookup?
A: It depends on the campsite’s power. Many standard hookups are 30 amps, which might be enough for some smaller units, but a 50-amp service is often recommended for better performance.
Q: Will an electric tankless water heater work if my RV is not plugged into shore power?
A: No, electric tankless water heaters need a constant and strong electrical source. They will not work with just your RV’s batteries or a generator unless the generator is powerful enough to meet the heater’s requirements.
Q: How long does hot water last with an electric tankless heater?
A: It lasts as long as you have hot water flowing through it and sufficient power. You don’t run out of hot water like you do with a tank heater.
Q: Are electric tankless water heaters safe for RVs?
A: Yes, when installed correctly and with proper safety features, they are very safe. Look for models with built-in safety shut-offs.
Q: What is the typical lifespan of an electric tankless water heater for an RV?
A: With proper maintenance, they can last 10 to 20 years, which is often longer than traditional tank water heaters.
Q: Do I need a special inverter for an electric tankless water heater?
A: Generally, no. Most RVs designed for 30-amp or 50-amp service already have the necessary electrical capacity. However, always confirm your RV’s electrical capabilities.
Q: Can I install an electric tankless water heater myself?
A: Some handy RV owners can install them. However, it involves working with electrical wiring and plumbing, so professional installation is recommended if you’re unsure.
Q: How do I maintain an electric tankless water heater?
A: Regular cleaning of the filter and occasional descaling (depending on your water hardness) will keep it working efficiently.
Q: What are the advantages of an electric tankless water heater over a propane one for an RV?
A: The main advantage is not needing to refill propane tanks. They are also often quieter and can be more energy-efficient if you have ample electrical power.
