My Buying Guides on Lp Rv Water Heater
When I decided to upgrade my RV setup, choosing the right LP (liquid propane) RV water heater was a top priority. After some research and hands-on experience, I want to share what I learned to help you pick the best one for your needs.
Understanding What an LP RV Water Heater Is
First off, an LP RV water heater uses liquid propane as fuel to heat water, which is perfect for RVs since it doesn’t rely on electricity alone. This means I can have hot water even when I’m off-grid or boondocking.
Key Factors I Considered Before Buying
1. Size and Capacity
I made sure to choose a water heater that matched the size of my RV and my typical water usage. Most models range from 6 to 10 gallons. If you travel solo or as a couple, 6 gallons might be enough, but for families, a larger tank is better to avoid running out of hot water quickly.
2. Heating Speed
I looked for a model with a fast recovery time, so I wouldn’t have to wait long for hot water after using it. Some LP water heaters heat water in just a few minutes, which is great when you’re in a hurry.
3. Energy Efficiency
Since propane can be costly, I paid attention to the efficiency ratings. A more efficient heater uses less propane to keep your water hot, saving money and extending my propane supply.
4. Installation and Compatibility
I checked whether the water heater would fit my RV’s existing water and propane systems. Some models are designed for easy retrofit, while others might require professional installation or modifications.
5. Safety Features
Safety is essential, so I looked for heaters with features like automatic shut-off, flame failure protection, and overheat sensors to avoid accidents.
Types of LP RV Water Heaters I Explored
- Tank-style water heaters: These store a set amount of hot water and are common in many RVs. They’re reliable but can run out if you use too much at once.
- Tankless (on-demand) water heaters: These heat water only when you need it, so you don’t run out. I found they save space and propane but tend to be more expensive upfront.
Additional Features That Made a Difference
- Digital controls: I appreciated models with easy-to-read digital panels for temperature adjustments.
- Dual power options: Some heaters can run on both propane and electric power, which adds flexibility when hooked up at a campsite.
- Compact design: Space is limited in an RV, so I preferred a compact model that didn’t take up too much room.
My Final Tips for Choosing Your LP RV Water Heater
- Assess your hot water needs based on who’s traveling and how you use water.
- Consider your typical camping style—boondocking or staying at RV parks—to decide on features like electric power options.
- Don’t forget to factor in installation costs if you need professional help.
- Read reviews from other RV owners to learn about reliability and real-world performance.
Choosing the right LP RV water heater made my RV trips much more comfortable. I hope my guide helps you find the perfect fit for your adventures!
