Eternal Water Heaters

Introduced to significant acclaim, Eternal Hybrid gas fired water heaters were introduced to the Denver market in 2006. They were a popular choice for Colorado home and business owners because they offered the efficiency of a condensing water system, and operated without the high flow rate restrictions typical of tankless water heaters.

In 2014 increasing problems with the Eternal heat exchanger and controls resulted in leaks and premature system failures. After a year of trying to correct the problems, Grand Hall, the parent company of Eternal Water Heaters, ceased operations in North America leaving their customers without warranty coverage, part replacements and technical resources.

Eternal Water Heater Repair

In some cases, we have the parts to make successful repairs. This is generally when they have NOT developed a leak, are not working properly or are displaying an error code.

Error Code E02

Ignition failure, possibly originating from a dirty flame detector rod. The unit should be checked by a certified and trained technician.

Error Code E27

The mixing valve didn’t initialize correctly, causing the servo stepper motor to flood. The fix may be disassembling, cleaning and drying the components. If this does not work, the part will need to be replaced, which is difficult as the parts are now quite rare. The unit should be checked by a certified and trained technician.
