WPS (Water Pressure Switch) Failure
This known design flaw corrodes the plastic and the switch over time, leading to the entire unit flooding. A retrofit was provided, but many units were installed without the repair kit.
When should I repair or replace a tankless water heater?
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. Common warning signs include:
- Scale build-up causing reduced efficiency and capacity
- Clogged or restricted inlet filters
- Intermittent flame failures caused by gas pressure problems
- Improper condensation or condensation leakage
- Changes in wait times for hot water
- Variable outlet water temperatures
- System requires constant resetting
Repair or Replace Your Eternal?
Grand Hall, the parent company of Eternal, stopped operating in North America, which left owners without factory warranty coverage or a reliable parts supply. We still repair Eternal units when the fault is in a part we can source, and we keep common parts on hand when we can get them.
Once an Eternal heat exchanger starts leaking, replacement is the practical answer. We will show you the repair cost next to the cost of a modern tankless or hybrid system so you can decide with real numbers.
Common Eternal Replacements
- High-efficiency tankless: Navien, Rinnai, or Noritz, sized for your household flow rate
- Hybrid heat pump water heater: Rheem ProTerra, eligible for Xcel Energy rebates
- Standard gas tank: the lowest upfront cost when budget comes first
