KEY FEATURES AND BUYING GUIDE

heatercamp These are some of the essential characteristics that an RV water heater must possess. They also form the basis of your choice.

Storage Capacity:

If the heater has a tank, it should be able to hold a substantial volume of water. When it comes to RV water heaters, there are three storage systems.

 We have 6 to 10-gallon tanks, 16-gallon tanks, and tankless RV water heaters. The 6 to 10-gallon containers are the most common and16-gallon tanks can hold water at a high temperature. The tankless heaters do not have a storage system. Hence, they deliver hot water as it is needed. They are very efficient and inexpensive.

Power source:

There are gas-powered and electricity-powered RV water heaters. The most common gases used for this purpose are liquefied petroleum gas and natural gas. Electric-powered water heaters get their power from generators or any 120V electricity outlet. It would be best if you considered the power source you have available before buying any RV heater.

Maintenance:

If an RV water heater cannot be maintained easily, do not buy it. There are different types of maintenances, and for an RV water heater, repair and preventive maintenances are the most important. Preventive maintenance has to do with avoiding a fault by ensuring strict compliance with the heater’s usage instructions. This task should be easy to do. Sadly, most people do not do it. They wait for the heater to develop a fault before trying to fix things. Please note that a certified technician should only repair this unit. Essential maintenance includes cleaning the heater and disconnecting it from the power source when it is not in use.

Size:

You don’t want to buy an RV water heater that will take up too much space. A right RV water heater saves space. Although you may think that the bigger the radiator is the better and more hot water it will be able to deliver. Situations are different in reality. Some small unit performs incredibly better than the bigger. That said, a compact design and moderate size is okay. A bulky RV water heater is not worth your time and money.

Design:

The design of an RV water heater is of high importance. A right RV water heater must be pleasing to the eye. Do not spend your money on an RV water heater that does not add to your recreational vehicle in terms of style. Remember, a recreational vehicle is a home away from home. The heater must bed in with existing decorations and furniture. If it does not add beauty to your recreational vehicle, do not buy it. No ugly or poorly-designed water heater deserves your hard-earned money.

Efficiency:

Efficiency is a comparison of what the heater offers against what it receives. In the case of an RV water heater, input energy comes from a gas or an electrical outlet. If the heater can produce an excellent heat output with a little input energy, it is worth it. Such an RV water heater does not need too much input energy to raise the temperature of water substantially. The more efficient an RV water heater is, the lesser the amount of electrical power it will consume. Consequently, there will be a massive reduction in your electricity and energy bill.

Ease of installation:

A right RV water heater should be easy to put together. Lighting should be as easy and straightforward as possible, albeit a licensed technician must do it. If an RV water heater is not easy to install, then you may have to reconsider your stance. Installation is the first real encounter a user will have with such a device, and it must leave a lasting impression.

Lightweight:

The fact that RV water heaters are not bulky is what makes them accessible. A right RV water heater should be convenient. When it is cumbersome, it becomes difficult to convey from place to place. Do not buy any RV water heater that is massively weighted.

Safety:

There is no point buying a device that will harm you or cause a bit of damage. Before you pay for an RV water heater, find out if it has been certified safe. If yes, look out for some of its features. Some of these features include overheating protection, anti-freeze protection, auto shut-off mechanism, anti-corrosion, and many more. Any manufacturer that fails to incorporate these things in an RV water heater is not serious about safety.  Do not buy such a unit.

Extra functions:

Nobody wants a hard life, and this explains why many manufacturers of RV water heaters have incorporated certain features and functionalities to this device. Before you buy an RV water heater, be sure you can operate the equipment digitally or remotely. This function is one of the essential features recently produced RV water heaters must-have. It makes it easier to adjust temperature settings and choose an ideal heating range without having to stand up or walk close to the unit. An RV water heater should also have a timer that allows you to decide the duration it will work.

CONCLUSION

There are so many options to choose from when it comes to RV water heaters. This article explains why you shouldn’t decide without thinking it through. Any decision you make should base on the strength of the chosen RV water heater and what it has to offer. Its power must exceed its weakness; it must have more advantages than disadvantages. It is important not to decide on which RV water heater to buy without first comparing and contrasting. It would be best if you weighed up all your options.
