Our Review

Safety is essential when using any type of tankless water heater, let alone a unit that can be disassembled and moved from place to place. Luckily, the Eccotemp L10 takes this need for added safety seriously by including a 20-minute automatic shutoff mechanism. In other words, if this unit is allowed to idle for 20 minutes, it will click its heating system off to prevent accidental overheating and internal damage. 

Also, novice users won’t need to question whether or not they’ve used the safest regulator for their particular propane tank size. That’s because the Eccotemp L10 comes with an appropriately sized regulator that will safely and efficiently convey propane gas into the unit without requiring any extra guesswork. 

Beyond that, installation proves to be pretty difficult and the hardware provided isn’t user-friendly at all. The process will most likely be frustrating, but for $160, it’s worth the manual labor. If you’re planning on using it for your whole house, we wouldn’t recommend this unit. It’s better for smaller properties, spaces, or projects, like barns, outhouses, RVs, worksheds, gardening, and camping. It’s also not the most durable model, so it will need regular maintenance, and potentially replacing, relatively soon after purchase.

Why Might I Want this Specific Tankless Water Heater?

In general, you might be drawn to any tankless water heater unit based upon their ability to provide instantaneous hot water without the need for a bulky, drum-like unit installed nearby. The Eccotemp L10 is certainly capable of performing this base-level function and so much more, including providing simplified hookups to allow users to tap into the unit’s propane-powered heating chambers in just minutes.

Also, some users may be attracted to this specific tankless water heater based upon its ability to heat water up to 160°F. While that is certainly too hot for human or pet bathing, those looking to complete gear and equipment cleanings using their Eccotemp L10 will be able to do so in a sanitary manner. This unit won’t take too long to heat up to peak temperature, either, due to its use of an extra-safe flameless ignition system.

Key Specifications and Features to Look for in a Tankless Water Heater

Dimensions & Capacity

When you trying to keep your hot water production and distribution system mobile, then matters of physical size are very important. The Eccotemp L10, for example, measures up at 14 x 25 x 8 inches, making it ideal for carrying from place to place and storing flat when not in use. Luckily, you won’t need to take capacity into account for any tankless water heat unit because they make use of an instant water heating process that makes internal storage redundant.

Fuel Type

Generally speaking, in-home tankless units are fueled by either electric, natural gas, or propane fuel sources. Mobile tankless units are generally limited to propane-fueled operation due to propane’s regular availability in a self-contained and portable form. The Eccotemp L10 is propane-powered accordingly, though it does use electricity from only two “D” cell batteries in order to activate its flame ignition system.

Flow Rate & Water Pressure

In all tankless units, flow rate describes the rate at which water passes through the unit and reaches the desired outlet. In mobile units, this metric is particularly important given the immediate proximity of the outlet point to the heating units (mere feet, in most cases). Without an optimal flow rate (such as the Eccotemp L10’s 2.65 gallons per minute capacity), users can expect undesirable drops in water pressure during use. This model provides great GPM and flow rate for small spaces like barns, worksheds, gardens, or outhouses. 

Heating Capacity

A tankless unit’s heating capacity is essentially the range of temperatures to which its core heating chambers can heat water during peak demand. The Eccotemp L10 features a broad heating capacity, for example, with the ability to heat cool or lukewarm groundwater up to between 80° – 160°F. Units with a higher heating capacity can be expected to fluctuate more when it comes to output water temperature.

Energy Efficiency Ratings 

Tankless water heaters are widely hailed for their overall energy efficiency, regardless of their fuel source. This is often expressing in a straightforward efficiency rating out of 100%. The Eccotemp L10, for example, features a 79% “energy factor” (another common term referring to energy efficiency). Though this notably lower than energy efficiency ratings for in-home tankless units, this 79% rating is fairly high for a mobile tankless unit.

Price and Warranty

Price comparison shopping is always important while looking for a tankless unit on a budget. The Eccotemp L10 comes in at a bargain compared to many other mobile tankless units, with a price tag just under $200. This includes a 1-year manufacturer’s warranty, which is important for ensuring that this (or any other) new tankless unit remain viable during its initial use period.

 Interface Type

In-home tankless units typically include some type of digital screen to communicate the unit’s present output temperature. The Eccotemp L10 makes use of a fully analog interface that includes dial for accessible temperature manipulation. While some may consider these knobs less than user-friendly, they serve their purpose on the Eccotemp L10 by visualizing the unit’s heating capacity continuum.

Different Uses for a Tankless Water Heater

 Hot Water on the Road

Whether you prefer a pop-up camper or an RV, a mobile tankless water heater like the Eccotemp L10 is ideal for travelers who want to enjoy a relaxing shower away from an established campground. Most mobile tankless units set up in mere minutes and are fueled by propane, a resource you’ve almost certainly already brought along on the trip to fuel your stoves. These units also pack up quickly and efficiently, making them easy to store when it’s time to hit the road once more.

Exterior Hot Water without the Piping

Tankless water heaters like the Eccotemp L10 don’t have to be used exclusively in their mobile orientation, though. In fact, these units are a great option for vacation property owners who want to add an outdoor shower without needing to add new water and electric infrastructure to their property. These units can be mounted on the exterior of a building and set up to take advantage of an existing hose pipe as well as a compact propane tank. When the offseason rolls around, these units can be de-mounted and stored inside just as easily to prevent internal damage.
