Buying guide: RV tankless water heaters
Every piece of RV equipment or furnishing requires much deliberation before purchase, and an RV tankless water heater is no different. To choose the right one for your vehicle, it’s crucial to understand the factors that make an RV tankless water heater desirable… and undesirable. We’ve put together a buying guide that covers everything you should know and consider before buying an RV tankless water heater.
What is an RV tankless water heater?
An RV tankless water heater, as the name suggests, is a water heating system without a tank that heats water instantly instead of heating all water present in the tank. While standard RV heaters consist of a tank that heats a limited amount of water (i.e., the given capacity of the water tank), an RV tankless water heater provides an unlimited supply of hot water. The RV tankless water heater mechanism is pretty simple– the water is heated as it passes through the pipes of the heater. Due to their accelerated ability to provide hot water, these heaters are also known as RV instant water heaters.
What are the benefits of an RV tankless water heater?
RV tankless water heaters have many benefits, and because of this these heaters have quickly replaced the traditional RV water heaters to become the first choice of RV owners. Some of the benefits include the following:
Size
A lack of space is an unfortunate aspect of most RVs, and installing a standard heater with a tank occupies a considerable amount of space that can be counterproductive, especially for smaller RVs. A tankless water heater is a lot more compact in comparison and thus proves to be incredible for saving space, which can be great for RV owners.
Unlimited water supply
A tankless water heater ensures that there is no limit to the amount of hot water provided, offering an endless stream of running hot water for use. This differs from standard RV heaters, where a limited quantity of water is stored in the tank and there’s a constant worry about running out of hot water. This is particularly beneficial for families with RVs that might require a significant supply of hot running water. With an unlimited supply of hot water, multiple hot water tasks, like showers or washing clothes or dishes, can be carried out simultaneously without having to worry.
No smell
It’s well-known that stagnant water tends to stink, and this is the case with the stagnant water in standard RV heating tanks. Since this doesn’t apply to RV tankless water heaters (as there’s no tank, to begin with), there won’t be any smelly water thanks to its running supply of freshwater.
Save money and energy
RV tankless water heaters help conserve water, and because there’s an instant supply of hot water none is wasted. These heaters are also quite energy-efficient, and they both save you money and help protect the environment in a small way. Tankless water heaters also have an extended service life and longer product maintenance warranty compared to the standard RV water heaters, so it’s a no-brainer to go for an RV tankless water heater if possible.
Types of RV tankless water heaters
The power source determines the type of RV tankless water heater. There are predominantly two types of RV tankless water heaters– electric-powered and gas-powered.
Electric-powered RV tankless water heater
Electric-powered RV tankless water heaters are powered by electricity obtained from either the RV’s electrical system or solar panel, or even from a ground source or external generator (in the case of a stationary RV). Electric-powered models offer many benefits, including ease of installation, cost-effectiveness, and an environmentally friendly solution.
Gas-powered RV tankless water heater
Since RVs don’t have access to natural gas, gas-powered RV tankless water heaters rely on kerosene and propane for heating. This type of heater is a lot more affordable compared to electric units, but there’s a significant installation cost involved– ventilation is required for a safe operation, meaning vents need to be installed along with the heating unit. Unlike electric units, gas-powered RV tankless water heaters are not environmentally friendly, as they release a small number of greenhouse gasses when in use.
How to choose an RV tankless water heater
When it comes to purchasing an RV tankless water heater, the final decision ultimately rests with you. Here are a few things to consider to help you make a great choice:
Size
RV tankless water heaters are much more compact than their standard counterparts. Think about the size and how the heater will fit in your RV to choose an appropriate unit.
Water flow rate
The water flow rate of a water heater is the amount of water, usually measured in gallons, heated, and supplied in a minute. Because of this, the water flow rate is measured in gallons per minute.
The water flow rate of an RV tankless water heater ranges from one to ten gallons per minute. The higher the water flow rate, the higher the price of the heating unit. On average, a heater with a water flow rate of two to three gallons per minute is an excellent choice for a family of RV campers.
Safety factor
Accidents are unfortunately common with heating units, whether they’re electric-powered or gas-powered. In the case of RVs, these accidents can prove to be lethal. To avoid danger, it’s advised to choose an RV water heater with self-limiting damage and other failsafe features that can prevent accidents.
Budget
Budget is always a crucial factor, no matter what it is you’re buying. RV tankless water heaters can be considerably more expensive than their standard counterparts, and the pricing of tankless units varies a great deal– RV tankless water heaters can range from $200 to $1,000 depending on the unit’s specifications. A solid RV tankless water heater can be purchased for $250 to $400, but if you want a more premium option you might have to spend up to $1,000, and sometimes even more than that.
People also asked
Q: Is a condensing RV tankless water heater better than a non-condensing one?
A: Non-condensing RV tankless water heaters feature a single heat exchanger, while a condensing one uses a dual heating mechanism in a double heat exchanger. The heat is recycled in the latter, making condensing RV tankless water heaters a lot more efficient. Lower exhaust energy and higher efficiency make this kind of heater a better option.
Q: Is it possible to replace an existing standard RV water heater with a tankless one?
A: It is, as tankless water heaters occupy considerably less space and can be easily fixed in place of a standard heater.
Q: Do RV tankless water heaters require maintenance?
A: Yes, RV tankless water heaters require annual maintenance from a professional to keep the heater in top condition for the future. Removing mineral buildups and fixing wear and tear proves instrumental in enhancing the service life of an RV tankless water heater.
Q: Do RV tankless water heaters require neutralizers?
A: Yes, the condensing type of RV tankless water heaters requires neutralizers to extend the life of drain pipes.
Q: How often do RV tankless heaters require descaling?
A: An RV tankless water heater should ideally be descaled twice a year, particularly in the case of hard water and high-temperature settings, but a yearly descaling should be fine too.
