Benefits of RV Tankless Water Heater
Still looking for reasons to be convinced that you need a tankless water heater for your motorhome? Below are some of its advantages:
- Compact Design: RVs do not have the luxury of space. Because of their small size, RV tankless water heaters are ideal. It can be installed in the bathroom of your motorhome without the need for a lot of space.
- Continuous Supply: Conventional heaters have tanks, and hence, they produce a limited amount of hot water. With a tankless water heater, on the other hand, you will have a continuous supply as long as there is a source of water.
- Adjustable Temperature: This will depend on the specific product that you will choose. Most of the newer models have a knob or dial that you can adjust depending on how hot you want the water to be.
- No Waiting: Another benefit is that there is no need to wait before the water becomes hot, making it a perfect product for people who are impatient. The moment you turn it on, hot water is ready.
- Energy-Efficiency: This is also dependent on the product that you will choose. Most of them, however, are designed in such a way that they will consume minimal energy while still delivering their peak performance. To be sure that it will be energy-efficient, choose products from trusted brands, such as Girard and Suburban.
Types of RV Tankless Water Heater
The type of the RV tankless water heater will depend on its source of power. That being said, below are three of the most common options that will confront you:
Propane Water Heater: This is the more common option for an RV tankless water heater. A gas burner and a flow sensor combine to heat the water. Its speed is twice as fast compared to the electric heater. It is also cheaper to maintain in the long run.
Electric Water Heater: If budget is your concern, this type is the cheaper option. It is also less complicated, which means that its installation can be accomplished easily. Another benefit is that it operates without making a loud noise.
Combination Type Water Heater: This is perhaps the best choice from the three types as it can offer the best of both worlds. You can choose to use either propane or electricity, depending on which one is available or which is safer for the given external conditions.
Choosing the Best RV Tankless Water Heater
To help you in narrowing down the choices, below are some of the most important things that you have to consider:
Flow Rate: This is one of the most important technical specifications that require your attention. Look at the GPM or gallons per minute. This refers to how much water can flow out of the shower head within a minute. The best options should have 2 to 2.5 GPM, especially if you are a small family.
Temperature: You also have to look at the maximum temperature that can be reached by the water heater. The higher is the temperature, the hotter the water will be. To add, it must also not take a long time before it becomes hot.
Energy Consumption: Most of the RV tankless water heaters operate with the use of propane, which allows water to become hot. See to it that it can reach the required temperature without requiring too much propane or electricity.
Installation: Choose one that is effortless to install. The manufacturer must provide comprehensive instructions on how the assembly can be completed. The kit should also be inclusive of everything that you will need, including the fittings.
Durability: Consider the materials and the overall design of the product. All parts, including the bypass valve, motor, and even shower head, should be rugged to withstand long-term use. The materials must be able to survive wear and tear, especially if you travel a lot in your RV.
Heat Output: This is measured in British Thermal Units or BTU. A higher number will be indicative of higher heat output. This means that you do not have to wait for a long time before water heats up.
Safety: It is also important to look at the safety features of the product, such as protection from freezing, overheating, and voltage spikes, among other external conditions that could possibly put you and your motorhome at risk.
Warranty: This is important as it provides you with peace of mind. The standard warranty is one year. Some manufacturers are generous enough to offer a lifetime warranty on labor and some parts. Do not buy a product if it does not come with a warranty.
Price: This should be the least of your priorities. A lot of you may be tempted to choose a product only because it is cheap. Nonetheless, I suggest that you emphasize quality and functionality over cost. It does not matter if you have to spend more if this means being able to enjoy a top-notch product.
Care and Maintenance for RV Tankless Water Heaters
Even if you choose the best product that you can find on the market, you need to pay attention to its care and maintenance.
Dealing with Hard Water
When you are on the road or in a campsite, you are not sure about the quality of the water supply. More often than not, you will be using hard water. This means that it can be prone to impurities and mineral deposits. Calcium and magnesium ions will most likely be present in the water. The scaly buildup can cause clogs.
Through a long time of exposure to hard water and mineral buildup, the functionality of your heater can be negatively affected. The heating efficiency will no longer be as commendable. The internal parts of the heater can also be damaged.
One of the solutions that you can consider is to use a filter, which will remove the impurities from the water before they reach the RV tankless water heater. Flushing your heater annually is also necessary. Using a combination of white vinegar and water will help to effectively get rid of this build-up without the need to resort to toxic methods.
Aside from the use of a filter, a scale prevention shield can also extend a helping hand. In a nutshell, the latter is a product that has the primary function of preventing the components from hard water from attaching to the heating chamber.
Refer to the Manual from the Manufacturer
For basic troubleshooting and maintenance, you should take the time to consult the manual and follow the instructions that have been specified by the manufacturer. While there are many resources that are available online, the problem is that the steps may not be specific to the model of the water heater that you are using in your RV.
Perform Regular Inspection
You do not need to be a pro to inspect the RV tankless water heater. By performing a regular inspection, you will be able to identify the problem early on and prevent it from escalating.
One of the things that you should check is the venting. Most models have a venting system that is fan-operated. Make sure that the vents are working properly, which will lessen the likelihood of suffering from a fire. This is especially important if your unit is powered by propane.
Other Tips for Using RV Tankless Water Heater
For your safety and for the heater’s optimal performance, keep these things in mind:
Do not use parts and accessories that are not provided or approved by the manufacturer. If there are some components that need to be replaced, see to it that you buy ones that are compatible with your heater.
If you have a propane-powered tankless water heater, avoid using it when you are driving. This is because the incoming air can have an impact on the pilot light or flame. This can start a fire.
Choose the right location in the RV. Make sure that it is in a place where it will not get wet or it is not exposed to external elements that could speed up wear and tear. It should also be placed as close as possible to the source of water.
Turn off the heater when it is not being used. This will not only help to save energy consumption, but will also prevent heating and other potential problems, especially if the unit uses gas to heat water.
The best RV tankless water heater is a must-have for motorhomes. It makes sure that you will have hot water on demand, making it possible to have a relaxing shower. However, with the multiplicity of the options, do not pick just any model on the basis of price. Take time to evaluate all factors, including those briefly outlined in this guide.
