Best RV Propane Water Heaters Buying Guide For 2022-2023

If you are already searching for an RV water heater, there is a good possibility that you have already gone through hundreds of options and cannot get the best choice for your needs.

Hence, we are here to help you with that. Along with the features mentioned above, there are many other things that you should consider before buying an RV propane water heater.

Even though you can find the detailed specifications with each of our recommendations for the best heater, you should know how these features affect the day to day application for an individual. Thus, we will be discussing the same in our buying guide given here.

Power Source:

There are mainly 3 types of RV heaters available in the market that are electric, propane, and natural gas-powered heaters.

Depending upon the power source accessible for you, you should carefully select the correct choice for your RV. Considering the eco-friendly usage, you should prefer the electrical option if there is a powerful battery in your RV. But, in case your battery cannot suffice for the input requirements of the heater.

You will have to go for a hybrid option or a propane-powered option. You can also go with the LPG option if you are on a tight budget.

Water Flow Rate:

The water flow rate available with the water heater can also be a crucial factor that you should carefully examine before buying the heater.

Generally, the flow rate is given in GPM or gallons per minute rating and it represents the amount of water you will get per minute. For a single person, even 2 GPM water should be sufficient. But in the case of large groups or families, you should prefer a little higher water flow rate option, providing you with at least 5 GPM or higher water flow rate.

This way, you can ensure that you will be getting a sufficient supply of water at a steady temperature.

Size & Form Factor:

Considering the fact that you are buying the water heater for your RV, the size and form factor becomes a very important aspect.

Not all RVs have sufficient spacing available in the bathroom or the kitchen to install a large-sized heater. Instead, some RVs require a completely portable device so that no additional space is required.

The best way to get the perfectly compatible option is to look at the dimensions of the product beforehand and compare it with a suitable installation location in your RV. This way, you can confirm the compatibility of size even before getting the product.

Power Capacity:

With a high power unit, you will be able to gain a higher temperature rise in the input water supply.

Thus, it will be a more suitable choice for colder locations where the ambient temperature is lower. Although, if you live in a high-temperature region, you shall not require a high power unit.
