Signs it's time to replace

Most hot water systems fail without much warning.

Tanks are built to a lifespan, and once they're past it, small issues can turn into a flooded laundry or garage overnight. If any of this sounds familiar, it's worth getting a system checked before it fails on its own terms.

  • Hot water running out faster than it used to
  • Rusty, discoloured or metallic-tasting water
  • Tank is 8–10+ years old, or visibly corroding
  • Damp patches or pooling water around the unit
Not sure which system?

We'll size it to your household.

Family of two or six, mains gas or none, north-facing roof or not — the right system depends on your home. We assess your setup on-site and recommend what actually suits it, not just what's on the truck.

System types we install

Electric, gas, solar or instantaneous — fitted properly.

Electric

Electric hot water systems

Simple, reliable storage tanks that suit most homes — a straightforward swap when your current electric unit is due for replacement.

Gas

Gas hot water systems

Faster recovery and lower running costs where mains or bottled gas is available, installed and certified by a licensed gasfitter.

Solar

Solar hot water systems

Roof or ground-mounted collectors paired with a gas or electric booster, for households looking to cut long-term running costs.

Instantaneous

Instantaneous (continuous flow)

Compact, tankless units that heat water on demand — no storage tank, no standing heat loss, and hot water that doesn't run out.

How it works

Three steps to hot water again.

01

Call or book online

Tell us what's happening — no hot water, an old tank, or planning ahead. We'll talk through your options over the phone.

02

We assess & recommend

Our installer checks your existing setup, roof and gas access, and household size, then gives you an upfront, fixed price for the right system.

03

We install & set it up

Old unit removed, new one installed and commissioned to manufacturer spec, with the warranty registered before we leave.
