Benefits Of Owning A Eccotemp L5

Lightweight and compact design

Weighing at just 13.8lbs (6.25kg), the L5 tankless water heater can be transported easily to campsites, lonely cabins, and to almost any off-the-grid locations. Its compact design keeps it out of the way, allowing a temporary set-up that can be fitted conveniently at almost any outdoor locations.

Versatility in deployment

The Eccotemp L5 portable tankless water heater can be deployed anywhere be it a campsite, at the beach or even at outdoor sinks to do your dishes! It has also been deployed even on boats and trailers highlighting its versatility. Its battery operated ignition giving you control over the flame.

When deciding a place for installing the Eccotemp L5, take note that it requires a 2″ clearance from a wall, 1″ side to side from anything flammable, 3″ from a window as well from an overhang, and 18″ from the ground. 

For installation at elevated areas, the Eccotemp L5 has been tested for use at elevations up to 2000 feet. So installation above 2000 feet may affect overall product efficiency and performance, while installation above 5000 feet is not recommended.

When you buy the L5, the below items are provided, 

  • 1 x CSA certified gas regulator and hose for use with standard 20-pound (lb.) grill propane tank

Easy to Operate 

The L5 can be connected to a standard garden hose nozzle and propane tank (tank not included). With its automatic ignition, the burners will come on as soon as the water flows. So get hot water, simply turn on the tap and you will get a constant flow within seconds. Multiple spray settings are available for you to select a preferred water pressure.

Off-the-Grid Operation

The Eccotemp L5 runs on liquid propane; a standard 20 pounds (lbs) tank of liquid propane can last for approximately 18 hours of continuous usage. The battery-operated ignition, powered by 2 D-cell batteries (not included), makes this tankless water heater a handy backup water source when electricity is not available and ideal for use during emergency.

Customer Reviews for Eccotemp L5

I have read reviews for Eccotemp L5 from verified purchasers and summarised them below. For more information, there is also a helpful FAQ on the Eccotemp website that provides answers to commonly asked questions in terms of product installation and maintenance.

Installation and assembly

Clear instruction manual, ease of installation are some of the mentioned positives. The provided accessories, fittings etc. are readily available in most hardware stores if additional ones are required for modification to suit your installation. 


Complaints of defects on purchased products ranging from missing LED power indicator light; thin heating coils, defective shower heads were mentioned. The solenoid has been mentioned to be an inherent issue that might require tinkering by the customers with over the phone guidance by technical support based on available feedback from the customers. This is an issue for those customers who are not so handy with the tools and can be better solved by improving the make of the product.     

A short heating time (in a matter of seconds) and low water flow is required to produce the hot water at the programmed temperature. This allows the conservation of water and propane. However, poor temperature regulation in production of hot water at a consistent temperature were mentioned by customers with one commenting that the fluctuations can take place within a space of 30 seconds.

Child protection function

The safety shut-off that will be activated when the unit runs longer than 20 minutes or when the unit is tilted more than 45 degrees in either direction reduces the chances of mis-handling by young children.  

Not fully outdoor installation

Though rated for outdoor use, the Eccotemp L5 can not be left permanently outdoors and should be retrieved and taken indoors. Drain out the unit thoroughly before storage. This unit does not have any anti-freezing technology therefore it is important to drain out all the residual water in the unit before storage to prevent freezing damage. However, Eccotemp has other units like 45H/HI, EL22/EL22i, 20H/20HI that have in-built anti-freeze technology. 

The unit is not suitable for deployment at windy sites. The battery-powered ignition pilot flame can be extinguished by wind giving you momentarily spurts of cold water until you switch on the flame again.

Another thing to consider, will be the inherent water conditions like temperature and mineral content, where the unit is to be installed. There was feedback that this unit has an issue with mineral scaling and rust. It is recommended that the unit be cleaned out thoroughly using cleaning agents like the EZ-Flush descaler kit every six months. This cleaning agent is also suitable for other water-based equipment. 

In the event of transportation, customers have mentioned that it is safer to provide a protective cover like a heavy plastic bag when transporting it from point to point to avoid damages to the unit. 

Customer Service

The reviews on the customer service/ technical support were mixed with both complaints and praises from customers. The technical support, when contactable, were able to provide good over-the-phone guidance to help customers to troubleshoot issues that arise while using the water heater. However, the complaints about the customer service were their unresponsiveness and unavailability by phone or email. Warranty not being honored was also a mentioned issue with one customer having to carry out repair work on the heater while the warranty was still valid.    

Warranty Information

The Eccotemp L5 portable tankless water heater is covered by a one-year limited warranty on parts while the unit remains at its original point of installation. This warranty takes effect on the date of installation, or 30 days after the date of purchase, whichever occurs first, for the heat exchanger (1 year), all other parts (1 year) and for the free accessories (shower head, hose, regulator, etc) (30 days).

Eccotemp will also provide 1 round of parts per incident (deemed by Eccotemp Support Team) under the warranty prior to requesting the shipment of any item to our warehouse for repair/inspection.

The coverage are void for the below criteria:

  • If this unit is used in a hot water circulation loop, in series with a circulation system or where an on-demand recirculation system is not incorporated.
  • The unit is a permanent installation for both indoors and outdoors since it is for outdoor, temporary use only.
  • No coverage for freezing damage as this unit does not possess in-built anti-freeze technology. 

The Eccotemp after-sales customer service, is also on standby 24 hours a day, 7 days a week at 866-356-1992 toll-free. More information on the warranty is available here.
