There are a number of reasons which could explain why you have no hot water. Some of the possible causes are shown below.
- Network fault
- Hot water cylinder drained
- Internal plumbing fault (leak or an overflow etc.)
- Internal electrical fault (blown element, fuse, thermostat).
- A ripple relay (controlled load management) fault
- Heavy load controlling (typical in winter)
Problems with your water cylinder are also one of the leading causes for unexpectedly high power bills.
Before we send a technician to investigate why you have no hot water, rule out any internal issues first. If a technician is dispatched and finds no fault with energyclubnz or your local network's equipment, then you may be charged a fee for the visit.
Did you have hot water earlier in the day?
This indicates your water heated overnight. The cylinder has likely drained and water will take some time to reheat. If you have a Night Meter, then the cylinder has likely been drained and water will not heat again until 11pm. If you have a Controlled meter, check if the hot water turns on again in the afternoon.
Has the fuse blown?
On your switchboard there should be a fuse labelled hot water. If there are no labels check that all your fuses are in the right position.
Have you had work done to the cylinder?
If so, it may be incomplete or have triggered an electrical short. If this is a possibility, the trade-person who carried out the work should be the first to investigate the issue.
Is your cylinder on a digital timer?
Is it still scheduled to run at your planned times? In some cases electricity outages can reset the schedule, preventing the water heater from heating up.
Is water leaking from the cylinder or anywhere else in the house?
If water is leaking from the cylinder, a plumber may be able plug the leak. Or you may require a replacement cylinder. You should also check your hot water taps and any other hot water pipes in the house and if they are leaking, get a plumber to fix them.
Is the water heater switch on?
Sometimes moving items inside a hot water cupboard can be accidentally switch the heater off.
Has there been more hot water used than usual?
Having guests stay, taking longer than usual showers, and heavy loads of hot-wash laundry may result in your cylinder running out of hot water. If this is a frequent occurrence you may need to review if the size of your cylinder meets your requirements. If you use a timer you may also need to adjust the schedule so that water is heated to meet your needs.
If none of these explain why you have no hot water you should log a fault.
