    Default Envirotech ESI-2000 service manual

    I have two Envirotech ESI-2000 electric tankless water heaters (28KW), one of which has recently started to malfunction after 4 years. Specifically, the overtemperature cutout breaker keeps tripping, not allowing the heating element relays to be activated (energized). The cutout can be reset, but it trips a few days later. I cannot locate a wiring diagram or service manual anywhere. An internet search yields nothing. I have checked the obvious things. Power inputs are all active, no clogged filters, and I replaced the flow sensor (since I happen to have 2 extras).

    I am aware that Envirotech Systems Worldwide, Inc. has ceased to exist due to contractural lawsuits and has been bought out (or reformed) by Skye International, Inc. Unfortunately, the latter does not wish to support this product. I am surprised that an internet search has revealed zero results. I know the company is out of business, but it is as if all references to almost any information about this unit have been erased from the planet. I can get a schematic for a thirty year old television, immigration records from 1918; why can't I find any service information on the Envirotech ESI-2000?

    I'm just starting to work with an old friend of mine to bring solar electric and hot water systems, wind turbines, Flex Fuel Boilers, batteries, hydroponic gardening, books, pellet grills and more. Also the parts for DIY installation.

    Default Envirotech Sytems ESI Flow Sensor

    My flow sensor on my ESI-2000 tankless water heater is acting up (due to sediment I believe - I've fixed a few times by tapping on the outside of the sensor, but it is now not working so well). You mentioned you had a few spare flow sensors. Where did you get them? Do you have a part number?
    Thanks - Joe

    That would just tell you how it is built, not how to service it.

    Very often, when companies are bought up, the former product line is left to wither on the vine. All the in-house corporate memory bank folks are let go, documents are not retained.

    Try to find support at AmStd for an old eljer Titan or Aquasaver. Try to find support for an old Thermador range....that brand has been bought and sold more often than Kunte Kinte!

    There used to be a little old appliance repair shop locally. He had sets of microfice cards going WAY back, and could help you track down these things sometimes. Now he is gone, and so is the microfiche, probably@

    Default Envirotech ESI-2000

    Just to keep this thread going for those of us who own these wonderful (when they work!) units. Here is THE GUY for Envirotech ESI-2000 water heaters. He can supply parts, manuals, even rebuilt units. He has helped us numerous times with our two units, the oldest one being 11 years old now.

    Good luck.

    Default Mine just went bad

    I will probably be selling my bad one if we replace it. It looks like it has a slow leak coming from the top, any idea what that might be?

    Thanks, Randy

    Default ESI 2000 Tankless Lek

    24.Jan.14
    Hi Randy.
    It appears that my unit started to leak as well today from the top. Were you able to repair your unit or did you have to replace it? If you id repair it, would you be so kind as to let me know how you did it?
    Thank you
