Storage versus continuous-flow hot water

What it could mean

Understand the symptoms.

Storage and continuous-flow systems differ in space, supply needs and how hot water is delivered.

What to do next

Compare installation requirements, simultaneous use, household patterns and lifecycle costs rather than headline efficiency alone.

When a plumber should assess it

If the fault continues, is affecting other fixtures, risks damage or cannot be identified safely, arrange a professional assessment. Similar symptoms can have different causes, so an inspection is needed before confirming a repair.

What to tell us

• Your suburb and the affected fixture or system
• Whether the problem is continuous or intermittent
• Any noises, visible leaks, odours or recent changes
• Whether it involves a single fixture or several

This article is general guidance. Do not attempt electrical, gas, pressurised, confined-space or unsafe drainage work.
