Hot-water
repairs.

Check the pattern without opening the appliance: are all hot taps cold, or is only one shower affected? Did it stop suddenly, follow a power interruption, or become less reliable over time? Note a visible display or error code and your system type if known.

A single affected fixture can point to a local mixer or supply issue. Cold water throughout the home can involve the heater, power or gas supply, controls or other components. These observations narrow the assessment; they do not prove an element or thermostat has failed.

Could controlled hot water explain cold taps?

Some electric cylinders have a controlled electricity supply. Wellington Electricity explains load control: a ripple signal can temporarily stop water heating while already-heated water remains available. This can happen without a whole-house power cut. Your electricity retailer may also control heating where you have agreed to it.

Ask your retailer whether your hot-water supply is controlled and whether an interruption affects your address. This is not a live outage report or a diagnosis of your cylinder. If no supply issue is confirmed or the problem continues, arrange fault assessment. Do not bypass a ripple relay, open electrical covers or repeatedly reset a tripping circuit. For a leak or immediate safety concern, follow the safety advice rather than waiting for supply information.

Do not remove covers, adjust thermostats, touch wiring, relight a faulty gas appliance or repeatedly reset a tripping circuit. If the fault is assessed as requiring the combined element and thermostat replacement, the approved price is $495 + GST including parts and labour. The $190 + GST site fee is not added to that repair. See repair prices and conditions, or call for fault assessment.

No hot water versus water that is not hot enough

All taps cold from the start: note whether the whole home has power and whether the heater display is on, without touching switches near water or opening anything. A supply interruption, control or heating fault needs to be distinguished from an exhausted tank. Ask your electricity retailer about a known controlled-hot-water interruption if applicable; do not assume every cold-water fault is load control.

Lukewarm from the first draw: tell us whether this happens at every outlet or just one. Mixing, tempering, control or supply faults can have similar symptoms. Hot initially, then cold: note how long the hot water lasts and whether it recovers later. These are different patterns and do not establish the same repair.

From a safe, dry position, note whether water appears at a visible pipe joint, a valve, the cylinder casing or the floor below. Tell us whether it is a drip or steady flow and if it is spreading. Water can track from another point, so a wet floor alone does not establish that the tank has failed.

Keep people away from hot water and wet electrical equipment. Do not touch wet switches, remove covers or attempt to tighten or repair a valve. If you cannot safely approach the system, stay clear and call. In immediate danger, move to safety and call 111.

Leaking cylinders and pipes are assessed and quoted separately; the fixed component-repair menu is not a cylinder or pipe replacement price. Call 022 078 1825 about a leak. If replacement is needed, compare the approved replacement prices and inclusions before agreeing the scope.

Tank leak or valve discharge?

Water visibly leaving a relief or expansion drain is not the same observation as water emerging from the cylinder casing. A connection leak can also run down the outside and collect under the tank. Note the apparent starting point only if you can see it safely; insulation and concealed pipework can hide the true source.

A confirmed leak from the storage vessel commonly means the cylinder itself needs replacement, whereas a valve or connection problem may be repairable. Neither a wet floor nor a running drain alone proves a failed tank. Do not remove insulation, climb to a roof outlet or feel the water to trace the leak. Tell us if it is spreading towards electrical equipment or damaging a ceiling so we can discuss safe next steps promptly.

Tell us whether the water starts hot then runs cold, is lukewarm from the start, or varies between taps. Has household demand changed, are showers overlapping, or is this a new problem with the same routine? Note the cylinder capacity if its label is safely visible and whether hot water recovers later.

Increased demand and recovery time can explain some shortages, but a heating fault, a mixing or tempering issue, or a leak may produce similar symptoms. We assess those possibilities before recommending a bigger cylinder. Do not turn up the thermostat or bypass a tempering valve: that can create a scalding risk.

An assessed tempering-valve replacement is $495 + GST including parts and labour; it is not a universal fix for running out. Check the repair menu or arrange an assessment. For a demand-related upgrade, compare capacity and recovery considerations.

New fault or changed demand?

A gradual shortage after extra people move in differs from a sudden shortage with the same shower routine. Note any changed timer schedule or safely visible error message, and whether the issue occurs after several uses or after the system has been left to recover. Share observations; do not alter heater temperatures, open controls or keep testing with more hot-water draws when a leak or safety concern is present.

Some systems release a small amount of water during heating, but a continuous flow, a marked change from normal or hot discharge needs assessment. From a safe position, describe where the outlet is, whether it drips or flows continuously and when you first noticed it. Do not touch the discharge to check its temperature.

Never cap, block or restrict an overflow or relief outlet. Do not operate or dismantle valves as a diagnostic test. Continuous discharge can relate to a faulty valve, pressure or temperature-control problems; replacing a valve is not automatically the right solution.

When diagnosis confirms a faulty continuously running relief valve, the approved replacement is $495 + GST including parts and labour. Other causes require assessment and an agreed quote. See price conditions and call to describe the discharge.

When discharge needs a call

A small intermittent release during a heating cycle can be part of thermal expansion on some systems. Continuous flow outside heating periods, a sudden increase or steam is a reason to seek advice, not proof that a new valve will solve it. Keep clear of the outlet; never collect or touch discharge to test its temperature. If steam, scalding water or a major leak puts anyone in immediate danger, move away and call 111.

A deteriorating tank, repeated faults or a system that no longer meets household demand can make replacement worth considering. We compare the existing system’s condition and repair options with the requirements of a replacement rather than assuming a larger cylinder or a change of technology is always better.

For a replacement enquiry, share the number of people and bathrooms, when showers overlap, the existing cylinder’s model and capacity if visible, and access to its location. We assess pressure, space, connections and related trade work. Ask the quote to clarify removal of the old unit, valves and pipework, electrical or gas work, any approvals, and the expected interruption to hot water. Timing depends on the agreed scope and parts availability.

Call 022 078 1825 to discuss repair or replacement, or compare electric, gas and heat pump hot water.

Consider repair when assessment finds a replaceable component fault and the tank is otherwise serviceable. Ask what caused the fault, whether parts are available and what the quoted repair will address. The approved element and thermostat replacement, tempering-valve replacement and diagnosed faulty continuously running relief-valve replacement are each $495 + GST ($569.25 including GST), parts and labour included. They are not universal diagnoses or cylinder-replacement prices.

Consider replacement for a confirmed leaking storage vessel, deterioration, recurring faults or a system that no longer meets your demand. Age is useful context, not an automatic replacement deadline. Compare the current repair quote with the complete replacement scope, likely interruption, access, supply availability and any related trade work. We do not invent a remaining lifespan or guarantee a repair will prevent unrelated future faults.

The $190 + GST ($218.50 including GST) site fee applies where no parts are required. It is not added to a listed $495 repair and is not an unlimited-labour promise. Leaking cylinders, leaking pipes and other unpriced work are assessed and quoted separately. Confirm the applicable charge and scope before work begins.

See the complete repair menu, approved replacement costs and inclusions, or the detailed heat-pump comparison. Repairs stay outside the replacement calculator. Call 022 078 1825 to discuss the fault.
