Best Portable Tankless Water Heaters: A Complete Buying Guide

by Eccotemp Europe

Portable instantaneous water heaters are invaluable for those who enjoy outdoor activities, need off-grid water heating solutions, or simply want access to hot water in areas without standard plumbing. Whether you're heading out for camping, hiking, or an RV trip, or need hot water in remote locations, choosing the right portable instantaneous water heater can be a challenge. This guide will help you make an informed decision when selecting the ideal model for your needs.

Purpose and Use
The first consideration is the intended use of the portable instantaneous water heater. Different models are designed for various purposes, so identifying your specific needs is crucial. Will you use it for showers, washing dishes, or general outdoor use? For larger groups, you might require a more powerful model, while solo travelers might prefer something more compact and lightweight. If you're planning on using it for outdoor showers, make sure to look for models tailored for that need.

Heating Capacity
The capacity of a portable instantaneous water heater is an important factor to consider. It is measured in litres per minute (LPM), indicating how much water the heater can heat in a given period. For larger groups or colder climates, you’ll need a higher LPM rating to ensure a consistent supply of hot water. For more basic needs, such as washing hands or dishes, a lower LPM will suffice. If you require a shower, a model with 5-10 LPM will typically be necessary to provide a continuous flow of water at a comfortable temperature.

Fuel Type: Propane
Most portable instantaneous water heaters run on propane, and for good reason. Propane-powered models are ideal for outdoor use as they don’t require an electrical outlet and are quick to heat water. They are perfect for camping, RV trips, or any off-grid activity. If you’re venturing into remote areas or off-grid locations, a propane model is likely your best option.

Portability and Size
One of the key features of portable gas instantaneous water heaters is their portability. Whether you're hiking, camping, or road-tripping, you'll need a model that’s light and easy to carry. Many modern models are compact, lightweight, and come with carrying handles or storage bags for added convenience. When selecting the right size, consider how much storage space is available in your vehicle or camping gear. Some models are more compact than others, and portability may be a deciding factor depending on your plans.

Temperature Control
A quality portable instantaneous water heater should offer reliable temperature control. This will allow you to adjust the water to your preferred temperature, whether for a relaxing shower or boiling water for cooking. Some models feature adjustable thermostats, while others have automatic controls that adapt the temperature to the surrounding environment. It's important to check that the water heater includes mechanisms to prevent overheating. Look for models with safety features such as automatic shut-off valves to ensure the water heater won’t overheat.

Ease of Setup and Operation
Setting up a portable instantaneous water heater should be straightforward. Some models can be assembled and used within minutes, while others may require additional steps, such as connecting propane tanks. For beginners, it’s important to choose a water heater that comes with clear instructions and is simple to assemble. Also, think about how the heater operates during use. Some are more automated, needing minimal intervention, while others may require more manual adjustments. Choose a model that aligns with your comfort level in terms of operation.

Safety Features
Safety is paramount, especially for propane-powered models. Look for heaters with built-in safety features such as automatic shut-offs to prevent overheating, flameout protection, and anti-tilt switches that automatically turn off the portable instantaneous water heater if it is tipped over. If you use a propane model, ensure it has adequate ventilation and that you’re operating it in a well-ventilated area to avoid dangerous carbon monoxide buildup. Always adhere to safety guidelines when using gas-powered models. Taking the time to understand safety precautions will significantly reduce the risk of accidents.

Maintenance and Durability
A durable portable instantaneous water heater is essential for long-lasting performance. Opt for models made from high-quality materials, such as stainless steel or strong plastics, to withstand the wear and tear of outdoor environments. Checking the warranty and available customer support from the manufacturer is also important in case any issues arise. Regular maintenance is necessary to ensure efficient operation, which includes cleaning the water heater, checking for wear or damage, and making sure all connections (such as propane tanks) are secure. Some models may require periodic descaling or filter changes, so ensure you’re prepared for any ongoing maintenance needs.

Price and Brand Reputation
While it may be tempting to go for a budget model, prioritizing quality is crucial. Look for reputable brands known for their reliability and durability. Eccotemp offers a range of options to suit various needs. Compare features, warranties, and prices before purchasing. Often, spending a little more upfront can save you money in the long term by avoiding frequent repairs or replacements. 

Environmental Considerations
If environmental sustainability is important to you, consider an energy-efficient portable instantaneous water heater. Propane heaters, in particular, should be used in a way that minimizes their environmental impact. While propane models are effective, using them responsibly and ensuring they are well-maintained can reduce their ecological footprint.

Conclusion
Choosing the right portable instantaneous water heater depends on understanding your unique requirements and selecting a model that meets them. Pay attention to factors such as fuel type, heating capacity, portability, and safety features, and don’t forget to consider maintenance and durability. Whether you're camping in the wilds of Europe or simply need a reliable heating solution on the move, a portable instantaneous water heater can make your travels far more comfortable and convenient. By taking all these factors into account, you’ll be sure to choose a model that suits your needs and provides reliable service for years to come.
