Our crew repairs and maintains Eternal 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. We may be able to service and repair units that are not working properly, or are displaying an error code. Once the units develop a leak it’s generally time to consider replacing the system.

We have technicians available today for a diagnostic visit or to prepare an estimate to replace your existing Eternal water heater. Call (720) 912-5447, or click here today.
