What's different in Rockhampton
Mains gas is an option
Rockhampton is on the Queensland Government's list of natural gas distribution networks, so some homes can use piped gas. Others run on LPG. Check your bill, or the bottles, before pricing a gas unit.
Cooler July mornings
Rockhampton Aero's July mean minimum is 9.8°C, and it averages 1.0 day a year at 2°C or below. A heat pump draws heat from that air, so ask how the model you're quoted handles a cold start.
Sun, with a winter dip
Mean daily solar exposure at the airport is 20.2 MJ per square metre across the year, but 13.8 in June (1990 to 2026). Solar quotes should explain boosting through June and July.
Mostly houses
88.1% of occupied homes in the Rockhampton council area were separate houses at the 2021 Census, and 32.1% were rented. Renters should tell the landlord or agent before booking.
The rules any new system must meet
Queensland requires a temperature control device on every new and replacement hot water system, gas, electric, solar or heat pump. Read tempering valves for what it does.
Water must be heated to at least 60°C to prevent Legionella growing, and the state's guidance is a maximum of 50°C delivered at the taps. Leave the thermostat setting alone; Queensland Health says a licensed electrician should adjust it.
For solar and heat pump systems, the installer must be a hot water installer with the QBCC's solar and heat pump endorsement. For gas, the connection is licensed gas work.
Four types, Rockhampton notes
| Rockhampton considerations | Who can fit it | |
|---|---|---|
| Gas (mains or LPG) | Whether your street has mains gas, or the house runs on bottles; the appliance must match the gas. | A licensed gasfitter for the gas work, with the temperature control device fitted. |
| Electric storage | Tank size for the household. No electric restriction appears in Queensland's hot water guidance. | A licensed plumber. |
| Heat pump | Performance on 9.8°C July mornings, and where the outdoor unit goes. | An installer with the QBCC solar and heat pump endorsement. Models under 425 L on the register can create STCs. |
| Solar | Boosting through June, when exposure drops to 13.8 MJ per square metre a day. | The same endorsement. Systems under 700 L on the register can create STCs. |
Help with the cost
STCs, small-scale technology certificates, can take money off an eligible heat pump or solar system. Owners often assign them to an agent for a discount or a delayed cash payment, and they're issued until the scheme ends in 2030. See STCs explained.
Our research hasn't confirmed a current Queensland Government hot water rebate, so we haven't listed one. Any change will show on our Queensland rebates page.
Questions to ask a Rockhampton hot water plumber
- Can this system be repaired, or has the tank failed?
- Is my house on mains gas or LPG, and does this unit suit it?
- How does this heat pump perform on a cold July morning?
- Do you hold the QBCC solar and heat pump endorsement?
- Which STC discount is in the price, and is the model on the register?
If it fails without warning
Make it safe
For a leak, close the cold water valve into the unit. Turn off power at the switchboard, or the gas at the unit if it's safe.
Note the details
Brand, model, date and fuel type from the label.
Call a specialist
A hot water plumber can tell a failed part from a failed tank, and quote both ways if it's borderline.
What we would do
Find out if the house is on mains gas or LPG before you choose, because it changes what's practical. Get a repair-or-replace answer from a hot water specialist, then compare two types side by side, with the temperature control device and any STC discount written into each quote. For a heat pump, ask about cold-morning performance; for solar, ask about June. Check the installer's QBCC endorsement or gas work licence before you agree.
