Townsville conditions that shape the choice
Strong sun, softer in June
Townsville Aero's mean daily solar exposure is 21.1 MJ per square metre across the year, ranging from 15.5 in June to 25.7 in November (1990 to 2026). The station also averages 120.8 clear days a year. Any solar quote should explain how the booster covers the leaner months.
Warm nights, even in winter
The July mean minimum there is 13.9°C, and over 86 years the station has averaged 0.0 days at 2°C or below. A heat pump pulls its heat from the surrounding air, so ask the installer how the model you're quoted is rated.
More than a third of homes are rented
At the 2021 Census, 36.6% of occupied homes in the Townsville council area were rented, against 33.1% for Queensland. If you rent and the hot water dies, tell the landlord or agent before anyone is booked.
Gas here means checking which gas
Townsville isn't on the state's list of places with a natural gas distribution network. If your hot water runs on gas, confirm whether it's LPG or mains gas before you price a like-for-like swap.
Queensland's rules for a replacement
Every new or replacement hot water system in Queensland needs a temperature control device, whatever the type. That applies to a straight swap too. Our tempering valve page explains what the valve does.
Stored water has to reach at least 60°C, which is what keeps Legionella from growing. The state's guidance then limits water delivered to the taps to 50°C. Don't turn the thermostat down yourself: Queensland Health says a licensed electrician should make any adjustment.
Solar and heat pump systems have one more condition. They must be installed by a hot water installer who holds the QBCC's solar and heat pump endorsement, which you can check before you sign.
Picking a type for a Townsville home
| Worth asking about | Licences and certificates | |
|---|---|---|
| Electric storage | The tank size your household really uses, and where the temperature control device will sit. | A licensed plumber. Queensland's hot water guidance sets no restriction on replacing electric with electric. |
| Heat pump | Where the outdoor unit goes, and how close it is to bedrooms. | An endorsed installer. Air source models under 425 L that are on the register can create STCs. |
| Solar | Roof space and direction, and how boosting works on cloudy wet-season days. | An endorsed installer. Solar water heaters under 700 L on the register can create STCs. |
| Gas | Whether the house is set up for bottled LPG or mains gas. | A licensed gasfitter for the gas connection, plus the temperature control device. |
Paying for it
Small-scale technology certificates (STCs) are the federal help on eligible heat pump and solar systems. They're certificates, not a rebate: owners often sign them over to an agent in exchange for a discount or a delayed cash payment, and they're issued until the scheme ends in 2030. Read STCs explained before you compare quotes.
We haven't confirmed a current Queensland Government hot water rebate, so none is listed here. Our Queensland rebates page is where any confirmed change will appear.
No hot water this morning
Look for leaks first
If water is coming from the tank or a valve, shut the cold water valve into the unit and switch its power off at the switchboard.
Read the label
Photograph the brand, model and date. It tells the plumber what parts might fit and how old the system is.
Get a repair-or-replace answer
A hot water specialist can usually tell a failed element or thermostat from a tank that has given out.
Get the details in writing
For a replacement, ask for the temperature control device, the installer's endorsement and any STC discount to be shown on the quote.
What we would do
Ask for a repair-or-replace answer before anything else, and get it from someone who works on hot water all the time. If the tank is finished, compare at least one heat pump or solar quote alongside a like-for-like electric one, with the STC discount and the temperature control device spelt out. For solar or a heat pump, check the endorsement on the QBCC register yourself. The warm nights and long dry season are worth raising with the installer, but the quote should do the explaining, not you.
