Buying Guide for On Demand RV Water Heaters

Understanding On Demand RV Water Heaters

When I first considered upgrading my RV’s water heating system, I realized that on-demand water heaters, also known as tankless water heaters, could be the perfect solution. These units heat water directly as needed, providing a continuous supply without the bulk of a traditional tank. This means I can enjoy hot water for showers, dishes, and cooking without worrying about running out.

Benefits of On Demand Water Heaters

One of the main reasons I chose an on-demand water heater is the energy efficiency. Unlike traditional heaters that constantly maintain a reservoir of hot water, these units only use energy when I need hot water. This not only saves energy but also reduces my overall utility costs. Additionally, the compact size of these heaters frees up valuable space in my RV, which is always a plus.

Considerations Before Buying

Before making a purchase, I had to consider several factors. First, the water flow rate is crucial. I needed to determine how many fixtures would be using hot water simultaneously. This influenced my choice, as different models have varying flow rates, affecting performance during peak usage times.

Another aspect I focused on was the fuel type. I had the option between propane and electric models. I chose propane for its efficiency and the availability of fuel during my travels. Understanding my RV’s power supply capabilities also played a significant role in my decision.

Size and Installation Requirements

The size of the unit is another key factor. I measured the available space where I planned to install the heater. Most on-demand units are compact, but I wanted to ensure a perfect fit. I also looked into the installation requirements. Some units are more straightforward to install than others, and I wanted to avoid complicated setups that would require professional help.

Temperature Rise and Adjustability

Temperature rise is an important specification that I paid close attention to. It indicates how much the unit can heat the incoming water. I wanted to make sure it could handle colder water temperatures, especially during winter trips. Adjustable temperature settings were also appealing, allowing me to customize the hot water experience to my liking.

Durability and Warranty

Durability is essential for any RV appliance, and water heaters are no exception. I looked for models made from high-quality materials, as I know that frequent travel can be tough on equipment. Additionally, a solid warranty offered peace of mind, ensuring that I would be covered in case of any issues down the road.

Customer Reviews and Support

Before finalizing my decision, I spent time reading customer reviews. Hearing about other users’ experiences helped me gauge the reliability and performance of various models. I also considered the availability of customer support. A responsive company can make a significant difference if I run into any problems after purchase.

Final Thoughts

Choosing an on-demand RV water heater was a significant decision for me, and I took the time to research and evaluate my options carefully. By considering factors such as efficiency, size, fuel type, and user feedback, I felt confident in my choice. With the right on-demand water heater, I am ready to enjoy hot water on all my RV adventures.
