Repair or replace? If the tank still holds water and only a part has failed, that job sits on our hot water repair page. This page is for the end-of-life cylinder: the tank weeping at the seam, the system past economic fixing, the upgrade you have been putting off. The hot water page covers both.
When a New System Wins
A replacement makes sense when the tank itself is failing rather than a part inside it. Once a cylinder leaks at the seam or the rust runs brown from every tap, no element or valve swap will bring it back.
One Suburb, One Ageing Fleet
Griffin built out in a single stretch
Housing started in the late 1990s near the Brays Road and Bruce Highway corner, then most of the estates went up through the 2010s, so neighbouring houses carry cylinders of much the same age.
The originals are past their prime
Anodes, elements, thermostats and relief valves fitted at handover are now failing as a set, and a cylinder that far gone is usually better swapped than patched.
Heat pumps and solar are everywhere here
Postcode-area install records count 1773 heat pump units and 1705 solar systems, so compressor changes and roof panel work now sit beside plain tank swaps on our run.
What a Replacement Covers
A full replacement takes in the unit, the plumbing connections and the commissioning, sized to your household and your roof or ground space:
Heat Pump Systems
We size and fit a heat pump to suit the household, mount it clear of bedrooms, connect the water and power, and set it running so the family gets hot water that evening.
Solar Hot Water
We fit panels matched to the roof and a tank matched to the household, run the new pipe work, and set the tempering valve so water arrives at a safe temperature.
Electric Storage Units
We swap failed electric cylinders for new storage units matched to the existing connections, so a straightforward changeover keeps the wiring simple and the down time short.
Gas Instant Systems
We replace gas instant units with a new system pressure tested on the day, so the burners light cleanly, the tempering valve is set, and the hot water never really goes off.
Tank Size Upgrades
We can upsize the tank or the flow rate when a growing family keeps emptying the old one, matching the new unit to the number of bathrooms and the peak morning demand.
Old Unit Removal
We drain the cylinder, cut it out cleanly and take it away, so you are not left with a heavy dead tank cluttering the side path or beneath the floor.
Common Problems Behind a Replacement
The Tank Leaks
A cylinder weeping from the seam or the fittings has rusted through from the inside, and at that age a full new unit costs less than one fix after another.
The Water Runs Brown
Rust or sediment at every hot tap means the tank is shedding its own lining, so the cylinder has reached the end and the new unit stops it.
The Relief Valve Runs
A tempering or relief valve that drips and hisses non-stop can mean the tank is over-pressuring with age, and a new valve on a tired cylinder wastes the money.
The Unit Is Past Fifteen
A system well past the ten-year mark that needs a second major part has reached the point where one replacement beats another visit, and we say so plainly.
Why a Replacement Matters
A dead cylinder stops the house
Showers, laundry and dishes all run cold until the unit is swapped, and a family household feels it inside a day, so the changeover gets priority.
The right size saves money for years
A tank too small for the morning rush gets worked hard and runs out, while an oversized one heats water nobody uses, so we size to the household.
New units fail differently
A fresh system carries current valves and connections, so the next decade of service sits ahead of it rather than behind, and the old unit stops leaking without warning.

Hot Water Replacement Questions
Call (07) 3067 4272Do I need a bigger tank for a growing Griffin household?
Usually yes, because the census puts the average household here at 2.9 people and 60 percent of local homes have four or more bedrooms, so a larger tank stops the morning rush running dry.
Who pays for a replacement in a rented Griffin home?
The landlord carries it, because Queensland tenancy law hands repair costs to the owner, so raise it with your property manager and we send the written quote straight to them.
Can I switch from an electric cylinder to a heat pump?
Yes, and it is a common changeover on this patch, because the district's install records count 1773 heat pump units already fitted locally, so the water and wiring side is familiar work.
Does Unitywater's water quality affect a new system?
Only mildly, since Unitywater grades the local supply as mid-range rather than hard, so scale crusts up slowly and a new unit wears on its elements and valves instead.
What happens to the old cylinder after the swap?
We drain it, unhook it and load it on the truck, so no dead tank is left sitting on the side path or under the floor, and the new system is commissioned before we go.
