Warning Signs
Is it time to replace it?
Cylinders rarely fail without warning. These are the signs Wellington homeowners spot most often — the earlier you act on them, the more options you have.
Talk it through · 027 360 0378-
Age.
Most cylinders last 15–20 years. If yours is approaching that mark, it's worth planning ahead rather than waiting for it to fail.
-
Frequent repairs.
If you're calling a plumber out more than once a year for the same unit, replacement is usually more cost-effective.
-
Inconsistent temperature.
Water that runs hot then cold, or takes much longer to heat, often signals a failing element, thermostat, or sediment build-up.
-
Leaks or corrosion.
Rust-coloured water, visible corrosion, or puddles around the base typically mean the internal tank has deteriorated beyond repair.
-
No hot water at all.
Could be a simple fix like a tripped breaker, or it could mean the cylinder has failed entirely. Either way, call Zac on 027 360 0378 to get it diagnosed quickly.
The Honest Question
Repair, or replace?
Not every problem needs a new cylinder. Zac will assess the unit, explain what's wrong, and give you an honest recommendation — no pressure to replace something that doesn't need replacing.
Option A
Lower cost
Repair makes sense when…
- The unit is under 10–12 years old.
- The fault is a minor component — thermostat, element, valve.
- The tank itself is sound — no corrosion, no leaks.
- It's the first callout you've had on the unit.
Option B
Long-term value
Replacement is smarter when…
- The cylinder is 15+ years old.
- It's needed multiple repairs in recent years.
- There's structural damage — corroded tank, persistent leaks.
- You want to switch fuel source, or upgrade to mains pressure.
What We Install
Four options for hot water.
ZBF installs a range of hot water systems to suit different households and budgets. Each has its own trade-off between upfront cost, running cost, and how it fits the rest of your home. Zac will talk you through the best fit for your situation.

Pressure upgrade
Mains-pressure conversion
If you're replacing a low-pressure cylinder, upgrading to mains pressure gives stronger, more consistent flow at every tap.
