Kapaa water heaters run year round with no break
There's no winter here to slow things down. Winter nights average 62°F from December through February, so your water heater carries the same load every month of the year, with no season where it gets to rest easy.
Power is the other thing to watch. In Hawaii, 14% of households went at least 24 hours without electricity in 2024, and Kauai County has logged 11 damaging wind events over the past ten years. Most water heaters come back on by themselves once power returns. If yours doesn't, or the water runs lukewarm afterward, that points to a problem that was already there before the outage.

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?
- Most bottom leaks mean the tank itself has rusted through and is failing from the inside. Sediment builds up over the years and eats away at the tank liner until it lets go. Once the tank is leaking like this, patching it does not work, and the unit needs to be replaced rather than repaired. Sometimes what looks like a leak from the bottom is actually water dripping down from a loose fitting or the temperature and pressure relief valve above it, so it is worth having a contractor check where the water is really coming from before assuming the tank is bad.
- Why won't the pilot light on my water heater stay lit?
- A pilot that will not stay lit is usually a sign the thermocouple has worn out and is no longer sensing the flame correctly. When that happens, the gas valve shuts off the pilot as a safety measure even though the flame is burning fine. A dirty pilot tube or a draft in the closet can cause the same problem, so it is not always the thermocouple. A licensed contractor can test which part is at fault and replace it.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a clogged inlet filter are common issues, and each of those can be cleaned or replaced without swapping out the whole unit. A contractor can flush the system and test the parts to find out which one is causing the trouble.
