What it could mean
Understand the symptoms.
Heat-pump water heaters use electricity to transfer heat and may need suitable outdoor space and acoustic consideration.
What to do next
Check electrical requirements, ambient conditions, cylinder sizing, rebates and installation costs before choosing a model.
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
