FAQ

Frequently Asked Questions

How long does a water heater last in Hawaii?

Many tank heaters last around 8–12 years depending on water quality, usage and maintenance. A tank leaking from the bottom is at the end of its life — that's a replacement, not a repair.

Repair or replace?

Elements and thermostats are inexpensive repairs on a healthy tank. If the tank itself leaks, or the unit is old and needs a major part, replacement is usually the better spend.

Are there rebates for efficient water heaters?

Hawaii Energy has offered rebates on qualifying solar and heat pump water heaters. Programs change, so check their current offers before you buy — your pro can help you pick an eligible unit.
