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.
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.
Ignition failure, possibly originating from a dirty flame detector rod. The unit should be checked by a certified and trained technician.
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.
If your Eternal Water Heater develops a heat exchanger leak, it will need to be replaced. Unfortunately without support from the manufacturer there is no warranty on your existing unit.

This known design flaw will corrode the plastic and switch over time leading to the entire unit flooding. A retrofit was provided, but many units were installed without the kit repair.
We look at system age, repairs, parts availability, water quality, hot water demand and water heating technology innovation with you to determine if it’s time to make the move to a new tank or tankless system.
