How do on demand water heaters work in RVs?
On demand water heaters, also known as tankless water heaters, work differently than traditional water heaters in RVs. Instead of storing and heating a large amount of water in a tank, on demand water heaters heat water as it is needed.
When a hot water tap is turned on in an RV, cold water flows into the on demand water heater and is heated by a gas burner or electric heating element. The heated water then flows out of the unit and to the faucet or showerhead. Once the hot water tap is turned off, the on demand water heater shuts off until hot water is needed again.
On demand water heaters in RVs are typically powered by propane or electricity. Propane-powered units are more common in RVs because they are more energy-efficient and can be used even when the RV is not plugged into an electrical outlet.
One advantage of on demand water heaters in RVs is that they take up less space than traditional tank water heaters. However, they may have lower flow rates than tank water heaters, which means that multiple hot water taps cannot be used simultaneously. Overall, on demand water heaters are a convenient and energy-efficient option for providing hot water in RVs.
How much does it cost to replace an RV on demand water heater?
The cost of replacing an RV on demand water heater can vary depending on various factors such as the type of unit you are replacing, the brand of the new unit you choose, and the complexity of the installation process. On average, you can expect to spend anywhere between $500 to $1500 for a new RV on demand water heater installation. However, if you are replacing an older unit with a more modern and efficient model, the cost may be higher. Additionally, if you require professional installation services, the cost may be higher depending on the complexity of the job. It's always recommended to get quotes from multiple vendors before making a purchase decision, and to work with a reputable professional who can help you identify the best unit for your needs and budget.
What are the best brands for RV on demand water heaters?
When it comes to RV on-demand water heaters, there are several brands to choose from that offer high-quality products. One of the top brands in this category is the Rinnai brand, which is known for its energy-efficient and durable tankless water heaters. Another popular brand for RV on-demand water heaters is Atwood, which offers a range of products that are specifically designed for RVs and offer reliable performance.

What is the average lifespan of an on demand water heater for an RV?
The average lifespan of an on-demand water heater for an RV can vary depending on several factors. Generally, these water heaters are designed to last for several years, with an average lifespan of 8-12 years. However, certain factors can affect the lifespan of the unit, such as the quality of the water and how frequently it is used. If the water in the RV has high mineral content, it can cause buildup in the unit, which can decrease its efficiency and lifespan. Similarly, if the water heater is used frequently or for long periods, it can wear out faster. It's important to properly maintain the unit by flushing it regularly and addressing any issues promptly to ensure it lasts as long as possible. Additionally, using a water softener or water filter can help prolong the lifespan of the unit by reducing mineral buildup in the water.
What size on demand water heater is best for an RV?
When it comes to choosing the best on demand water heater for an RV, there are a few factors to consider. The size of the water heater should be based on the number of people using it, the climate you'll be traveling in, and your hot water needs.
For a smaller RV with one or two people, a 1.5 gallon per minute (GPM) water heater should be sufficient. However, for larger RVs with more people, a 2.5 GPM or even a 4 GPM water heater may be necessary.
It's important to note that colder climates will require a larger water heater to compensate for the colder incoming water. Additionally, if you plan on using hot water for tasks such as showering, washing dishes, and laundry, a larger water heater will be necessary.
Ultimately, it's best to consult with a professional or do extensive research before making a decision on the size of on demand water heater to ensure it meets your specific needs and requirements.
