Customer Reviews for Eccotemp L5

I have read many customer reviews for Eccotemp L5 and have summarised them below.

The Pros 🙂

Ease of installation and assembly; The clear instruction manual, ease of installation and well-packed condition of a brand new unit are some of the positives mentioned by customers,  

Good child protection function; there is only hot water when the L5 is turned on so no fear of scalding,

Consistent hot water temperature; water is also heated to the perfect temperature for this Eccotemp tankless water heater in a matter of seconds and remains consistent until there is no more fuel left,

After sales and technical support; customers have mentioned that the Eccotemp customer service to be efficient and responsive with cases where they were able to solve most of the complaints and problems encountered during installation and defects in provided parts. Replacement parts were also sent to the customers free-of-charge and within the same day.

The Cons 🙁

There are also some cons,

Minor defects in provided accessories; there were isolated cases of minor defects like insufficient threading in the joints for the provided adaptors like shower heads,

Sensitivity; avoid bumping it when setting the burner temperature, to prevent fluctuations that might freeze or scald you. However once it is set, the temperature will remain stable,

Not fully outdoor use; though rated for outdoor use, the Eccotemp L5 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. 

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.

There also have been cases of rusting at the joint parts and housing reported by customers who have installed this unit in a permanent outdoor sink setup for the washing of dishes.

Even though this Eccotemp tankless water heater is rated as a outdoor unit, like all tankless water heaters, do take into consideration of the inherent temperature of the water in your region to avoid freezing damage to your unit.

Slight inconveniences in changing tank; when changing to a new propane tank, you will need to run the water heater for a minute or so to purge the air from the propane line. During this period, you will not be able to get any hot water, until the air is all purged out.
