Traveling unconventionally is amazing, as you get to experience everything in a different way. From the way you travel to the way you get to see new locations that you decide you explore, every single element is taken to a whole new level. Traveling by car, van, bike, motorcycle, sleeping in a tent or in your own van, these are all non-traditional ways of experiencing new places and enjoying every single moment of them. However, if you are one of those people who don’t like to give up their basic comfort, such as washing whenever they feel like it, you will need a few accessories that are capable of making your life easier.

A portable water heater is a tank that is capable of heating the water so that you can wash yourself, your dishes or your clothing whenever needed. Most of these products have auto ignition mechanisms that start the heating process immediately after the water stream enters the system. Some of these products work using gas and some are electric. Choosing the best water heater for your needs is crucial, if you want to keep your costs low and increase your comfort.

Water heaters that are designed to be used outdoors are highly portable. They are small, compact and very practical. They fit in the back of the car and anywhere in a van. However, it is a bit more difficult to carry them if you decide to travel by motorcycle. The market is rich in portable water heaters. Some models come with regular tanks, while others are tankless.

Can you truly rely on a portable water heater?

Portable water heaters can be very helpful when traveling, but the question that arises is if all models are truly reliable or not. To find out if a water heater is compatible with your needs, you must determine the purpose of its use.  If you are planning a trip with your van or tent this summer, you also have to consider your need to wash yourself and clean your dishes and even clothes. A water heater that you can use in designated camp sites is essential to own in order to feel comfortable. Tankless water heaters are also used sometimes by those who want to have a back-up, in case the regular one breaks. Either way, you should know that there are plenty of models on the market that are high-quality and that you can use without having to worry about their capabilities.

Portable water heaters are mainly designed to work outdoors, using in-line installation. Some have inner tanks that are covered by warranty and some are tank-less. Tankless models draw cold water from a pipe and heat it using a heating element or a gas burner. These are very practical, but might have a limited flow rate, so make sure to check the specifications carefully.

What is the difference between a fixed and a portable water heater?

Fixed water heaters are larger in size, more complex, sturdy and meant to function for decades. While portable water heaters are also durable, they aren’t designed for daily indoor use. Some have limited flow rate, such as 2-5 gallons per minute. If you need to use a water heater with a higher flow rate, a model that runs on gas might be a better option. Portable water heaters offer the possibility to maintain the level of comfort that you have at home when traveling and eliminate the need of looking for sources of hot water all the time. They are suitable for showers if they include a shower head, as well as laundry. Fixed water heaters are built for more frequent use and don’t depend on these factors. They are meant to heat the water in the installation they are connected to immediately and indefinitely. If you have a large family and you just moved into a new home, a portable water heater can be a temporary solution, but on the long term, you will surely need one with a tank and a much higher power.

What are a water heater’s dependencies?

A portable water heater needs a power source and a water source. The water can be cold, its temperature doesn’t matter, as the heater will do its job according to its specifications. However, if you are planning to use it for showers and laundry, you will need several other accessories. The dependencies of a water heater are different from model to model. For instance, if you use a fully portable model, you will only need electricity and water. If you choose a tankless propane water heater, then you will need a propane tank, a 12V sink, a fuse box and a battery and a water tank.

Portable water heaters are extremely practical devices that help you bring the comfort that you need anywhere you go. If you love to go camping in remote areas where you can’t find any showers, then owning one will make your life so much easier. Of course, trying to become one with nature is amazing, especially when camping near clear waters, such as lakes or rivers, but you shouldn’t take risks. Sometimes, the weather is unpredictable and other times you simply have no choice but to buy a water heater, especially if you travel with children. More than that, dish washing cannot take place properly without any hot water.

Investing in a portable water heater is the best thing that you can do for yourself and your family if traveling unconventionally has become a habit. Modern such products are affordable, small-sized, lightweight and very easy to use. Choose the most practical one for your needs, depending on your personal preferences.
