Replacement, Repair or New Installation: We Cover All of It
Hot water cylinder replacement
Hot water cylinder replacement is our most common hot water job in Auckland. Cylinders that are ageing, leaking or no longer heating adequately get assessed on the spot. We'll tell you directly whether a repair is the right call or whether replacement makes more sense given the age and condition of the unit.
Hot water cylinder repairs
Hot water cylinder repairs cover element replacements, thermostat faults, pressure relief valve issues and inlet/outlet connection repairs. Where the cylinder itself is sound, a targeted repair is often the faster and more cost-effective resolution.
Leaking hot water cylinder
Leaking hot water cylinder jobs are treated as urgent. A slow leak around the base can indicate a compromised tank under pressure, and we prioritise these calls. If you're seeing water pooling around your unit, turn off the cold inlet valve and call us straight away.
Hot water cylinder installation
Hot water cylinder installation — for new builds, upsizes or system relocations, we manage the full installation including disposal of the old unit, tempering valve checks, pressure relief valve replacement and seismic restraint where required.
Repair or Replace: Here’s How We Call It

The most common question we get is whether to repair or replace.
- Cylinder under 8 years old with an isolated fault — repair is the right call in most cases
- Cylinder 10 years or older with an internal fault – replacement is the more cost-effective decision
- Active leak from the tank body – replacement is required; a leaking tank cannot be repaired
- Repeated faults on the same unit – replacement avoids the cycle of ongoing repair costs
- Upsizing or relocating – installation of a new unit is the starting point
How Much Does an Electric Hot Water Cylinder Cost?
Hot water cylinder costs in Auckland vary by cylinder size, type and installation complexity. As a general guide, standard 180L to 250L units suit most Auckland households and strike a good balance between capacity and upfront cost.

frequently asked questions
FAQs
for electric hot water cylinders
How do I know if I need a repair or a full replacement?
We assess the fault, the age of the cylinder and the likely cost of each option, then give you a direct recommendation. Get in touch and we'll talk you through what we find.
How long does hot water cylinder replacement in Auckland take?
Most replacements are completed in a single visit of two to four hours, depending on cylinder location and access. We can often schedule same or next‑day for urgent jobs
What size cylinder do I need?
A general guide is around 50L per person per day for electric storage cylinders, though actual usage varies by household. We'll recommend the right capacity when we quote, based on your specific setup.
Do you offer mains-pressure upgrades?
We do. If you’re on a low‑pressure system and want stronger water flow, we can install a new mains‑pressure cylinder and upgrade necessary plumbing.
My cylinder is leaking, what should I do right now?
Turn off the cold water inlet valve feeding the cylinder and switch off the element at the switchboard. Then call us straight away, as we treat leaking cylinder jobs as urgent and will talk you through next steps on the call.
Can you help if I want to switch to heat pump or gas hot water instead?
We install heat pump hot water systems and gas hot water alongside electric cylinders, and we're happy to walk you through the options at the replacement point. Call us and we'll give you the trade-offs based on your property and usage
What payment methods do you accept?
We accept direct deposit and credit card payments, outlined in our pricing page. Get in touch so we can walk you through the details.
