A 1200W element is a common choice for heating up galley or shower water on a small craft. When these coils build up scale or simply stop conducting heat, the water stays cold regardless of how long the system runs. Swapping in a fresh coil brings the tank back to full temperature quickly. It is a straightforward fix that stops you from relying on a kettle for your morning coffee or cleanup. Keeping an extra one tucked away in the locker avoids a cold shower after a long day at sea.
