Coos Bay asks a lot of a water heater
Homes here need heat from October through June, nine months of the year, and the water heater is working right alongside the furnace that whole time. Winter nights average 37°F from December through February, so the tank is drawing in colder water for most of the year, not just a few weeks of it.
Coos County has seen 24 winter storms and 74 damaging wind events over the past ten years, and power does go out. A gas water heater with a standing pilot keeps running through an outage. One with electronic ignition will not light until power is back, and if it does not come back on by itself once it is, that is worth a look.

A new water heater would cut about $390 a year off hot water for a typical Oregon home.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The most common cause is the tank itself, rusted through from the inside after years of sediment sitting on the bottom. Once the steel corrodes and a crack forms, the leak will not stop or seal itself, and the tank needs to be replaced. It can also be a loose drain valve or a fitting that has failed, which a contractor can check before condemning the tank. If the leak is actually coming from above, water can run down the outside of the tank and pool at the bottom, so the source is worth confirming before assuming the worst.
- Why won't the pilot light on my water heater stay lit?
- Most often the thermocouple has worn out and is no longer sensing the flame, so the gas valve shuts off as a safety measure. A dirty pilot orifice or a draft in the area can also blow the flame out or keep it too weak to hold. Thermocouples wear out over time and are a straightforward part to replace. If the pilot relights and goes out again within a minute or two, that points to the thermocouple rather than a one-time draft.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Igniters, flow sensors, and heat exchangers can all be replaced without swapping out the whole unit. Mineral buildup inside the heat exchanger is common and causes error codes or reduced hot water, and it can usually be cleared with a descaling flush rather than a replacement. A contractor can pull the error code from the unit's display and tell you which part is at fault.
