If your hot water heater sounds like it is running continuously, it is typically caused by constant heating cycles triggered by high hot water demand, a stuck or failed heating element, or continuous heat loss. On electric units, a shorted-out element or fused thermostat can keep power flowing indefinitely. Alternatively, a hidden hot water pipe leak or a dripping plumbing fixture causes the tank to constantly refill with cold water and reheat. Verification: Check your electric meter or gas meter to see if energy usage spikes continuously.
