Published by:

Many people are spending a lot of time in their recreational vehicle (RV) and travel long distances. The vehicle is usually equipped with all the appliances which are required for leading a comfortable life. The vehicle owner has to decide on the type of appliances which they will use in their RV after reviewing whether it is suitable for use in the vehicle based on size, energy consumption, durability and other factors. Hence a comparison of a RV Tankless Water Heater vs Regular Types is provided considering different features for those who wish to find the most suitable water heater for their RV.

Space required

A RV tankless heater does not have a storage tank for the storing the heated water which is produced. Hence it will take up less space in the vehicle and is more suitable for use in the recreational vehicle, since there is less space available in the vehicle. A regular water heater has a fairly large storage tank for storing the hot water. This will take up some space if used in the vehicle, hence most RV owners are preferring to use a tank-less heater. The weight of the tankless heater is also less, so less fuel will be required for the vehicle since fuel consumption depends on the vehicle weight.

Energy consumption

Since the water in the storage tank has to remain heated the regular water heaters are consuming far more electricity or energy. On the other hand, in tankless water heaters, the hot water is heated using a heat exchanger type mechanism and water is heated only when required. Hence the energy consumption of tankless heater is far less , making it more suitable for a RV, where energy sources are limited. The lower energy consumption of the tankless heater will also help to save money in the long term.

Energy source/ Fuel used

Most of the regular water heaters have a high power consumption and are connected to the electrical power supply since there are no limitations to how much power will be used. RV owners require hot water wherever their vehicle is , and an electric power connection is not available at all places. Hence a majority of the recreational vehicles are having gas powered water heaters, using propane gas. Most RVs have a propane gas tank which is used as a fuel for the heater and other appliances.


Another major consideration while choosing the water heater is the ease of installation. It is easier to install a conventional water heaters, since only direct connections for electricity and plumbing are required. On the other hand, installing a best rv heater is fairly complicated, and a skilled plumber is required to install the heater in a vehicle, so that it functions properly and efficiently


Since the design of the tank less heater is fairly complex and includes a heat exchanger and sensors for heating the water according to flow rate, the cost of the tank-less water heater is usually far more than a standard water heater with a tank. Typically the tankless heater will cost twice the price of a regular heater with a tank. However, since the tankless heater is more energy efficient, the amount saved in energy costs, will compensate for the higher initial investment being made.

For different brands, the price and using costs also vary a lot, some well know brand such as Rheem, Navien and Ecosmart etc are more famous for their long using time and cost effective products. Each brand has its own design styles, thus in purchasing, you should learn a bit basic knowledge on the brand from some expert reviews such as Ecosmart tankless water heater reviews. And there’s another vital tips: always buy a most suitable one but not the most expensive one!


Typically a regular water heater will have a life of approximately ten to fifteen years, when used in a family, while a tank-less RV water heater can be used for twenty years or more, almost twice as long. Thus it is cheaper to purchase a tank-less RV heater, though the initial cost is higher, because it can be used for a longer period of time without any replacement . In comparison, the regular heater will have to be replaced more often, so in addition to the cost of a new heater, the RV or home owner will also have to spend money on installation expenses, like removing the existing heater and installing the new heater, so that it is functioning properly in the same space.

Hence based on the above information, a tank-less heater is more suitable for a RV compared to a regular heater with a storage tank for hot water since it is more durable, compact and will consume far less energy for heating the same amount of water.
