Area-level records for the postcode count 668 solar hot water installs against 404 heat pump units, so plenty of homes here heat water on the roof. Those collectors age too, and the tank sitting low under a high-set house usually ages faster.
Hot Water Not Working but Cold Is Fine
Cold running fine narrows the fault to the hot side, and we run five checks in a set order, because each one rules something out:
- 1

Cold supply and isolation valve
the isolation valve on the cold line is open, and water reaches the unit.
- 2

Leaks
we inspect the tank body, the pipe joints, each valve and the relief line for damp.
- 3

One tap or every tap
an outage at a single outlet usually blames that outlet alone. Cold everywhere points further back, to the unit, its supply or the valves feeding it.
- 4

Gas or power
we confirm the unit's fuel or power supply is on and working.
- 5

Temperature at the tap
last, we test what actually arrives at the outlet.

The 50°C Hot Water Limit at the Tap
A temperature control device is the valve setup that keeps water reaching your taps at 50°C or below, while the water in storage sits at 60°C or hotter. Fifty degrees is enough for washing, and it cuts the scalding risk. Sixty in storage keeps Legionella bacteria from growing.
Queensland requires one wherever a water heater goes in new or replaces an old one, and a straight like-for-like swap is no exception. A brand-new hygiene fixture such as a shower pulls one in as well. A washer change or a new shower rose does not.

Repair or Replace a Hot Water System
The dividing line is the tank. A fault at a valve, a fitting or a part is a repair. A leak through the shell of the tank itself ends the tank, and the system gets replaced.
How old the unit is, and how it has been serviced, steer the decision as well. QBCC guidance puts a major service at roughly five-year intervals, more often on bore or tank water, and that figure is advice, not law. A unit past its service history with the same fault again earns a replacement conversation instead of a fourth repair.

What High-Set Houses Do to a Tank
High-set timber houses along Ashgrove Avenue often keep the hot water tank at ground level under the floor. Damp air and storm splash reach the base down there, and the tank's anode works hard.
The roof tells a different story. Solar collectors overhead cop sun-baked valves instead, and cool dry winter evenings are when tired tanks announce themselves: a wet slab, a cold shower, a call after dinner.
A tank that lets go under the house dumps its load into the laundry or the undercroft, which is a shut-off-first job. Our emergency plumber page runs through those opening steps.

Form 4 and Paperwork After a Replacement
A licensed plumber does the water side of a replacement, and where gas heats the water, a licensed gasfitter handles the fuel line. In a home that already stands, the job is notifiable work: no council permit, no inspection. Your plumber registers it with the QBCC on a Form 4 inside 10 business days and hands you a copy for your records.
Our gas fitting page covers what that gas licence allows, and a tempering valve fitted during a bathroom plumbing job follows the same 50°C rule.

Hot Water Questions We Get Asked
Call (07) 3524 7137Do plumbers fix hot water systems in Ashgrove?
Yes, repairs and replacements on water heaters and tempering valves are licensed plumbing work in Queensland. Where a unit burns gas, a licensed gasfitter looks after the fuel side.
Can a plumber install a hot water system?
Yes, and a swap in an existing house counts as notifiable work. Your plumber lodges a Form 4 with the QBCC within 10 business days and fits a temperature control device. Which unit suits the house gets sorted at the visit.
What do plumbers check when an Ashgrove home has no hot water?
We start at the cold-side isolation valve, then inspect the tank shell, the joints on the pipes, every valve and the relief line. Next comes whether one outlet or the whole house runs cold, the fuel or power reaching the unit, and the heat arriving at the tap.
Does replacing a hot water system need a permit?
No, Queensland treats a water heater swap in an existing house as notifiable work, which needs no council permit and no inspection. Your plumber lodges the Form 4 with the QBCC within 10 business days of finishing, and you receive a copy for your records.
Is no hot water an emergency for a tenant?
Yes, Queensland tenancy law lists a failed water heater as an emergency repair. The tenant rings the emergency contact named in the agreement.
