Heat Pump Hot Water in Queensland (2026): cost, rebates and what to know

By PumpSwap. Updated 23 September 2026. How we check

In Queensland, a heat pump hot water system typically costs $2,300 - $4,800 installed after rebates. At QLD energy prices a four-person home pays about $338 a year to run it, against $846 for gas storage and $1,315 for electric storage. That saves about $508 a year against gas storage and $977 against electric storage, so the extra cost over a like-for-like swap is paid back in roughly 2.4 years against gas and 1.9 against electric at these averages. A premium model or low hot water use stretches that towards the 3 to 5 years most households see.

Are heat pumps worth it in Queensland?

The case rests on running cost. A heat pump moves heat from the air instead of making it, so it uses a fraction of the electricity of an element. At QLD energy prices (31c/kWh electricity, 4c/MJ gas), a four-person home that uses about 200 litres of hot water a day pays roughly:

System	Running cost a year	Installed cost
Heat pump	$338	$2,300 - $4,800 after rebates
Gas storage	$846	$1,200 - $3,500
Electric storage	$1,315	$800 - $2,500

That saves about $508 a year against gas storage and $977 against electric storage, so the extra cost over a like-for-like swap is paid back in roughly 2.4 years against gas and 1.9 against electric at these averages. A premium model or low hot water use stretches that towards the 3 to 5 years most households see.

About 20% of Queensland households are on mains gas, so for most of them the comparison is with gas storage.

In July, usually the coldest month, Brisbane averages a minimum of 10.5°C at the Bureau of Meteorology's Brisbane station, and in January a maximum of 30.4°C. A heat pump runs near its best efficiency almost all year. Bureau of Meteorology, climate statistics for Brisbane

Running costs are PumpSwap's model at the state average tariffs above, for a 45°C temperature rise and a heat pump coefficient of performance of 3.5. Your tariff and usage will move the numbers.

Heat pump rebates in Queensland

Queensland has no state heat pump hot water rebate in 2026. The incentive available is the federal STC discount, typically $500 to $800, taken off the installer's quote. The Climate Smart Energy Savers cash-back, which paid $800 to $1,000 for heat pump and solar hot water, closed in December 2023.

The federal STC discount is typically $500 to $800 for a 2026 install and steps down every 1 January until 2030. Brisbane postcodes are in Clean Energy Regulator zone 3 for air source heat pumps. On the regulator's register the same model earns more certificates in zone 4, which covers Melbourne, than in zone 3. Clean Energy Regulator, postcode zones for solar water heaters and heat pumps

Beware of quotes that look too cheap

Because rebates come off the price, Queenslandsees advertised "from" prices that leave out half the job. Before comparing quotes, check each one covers:

removing and disposing of the old system, and capping the gas line if you are leaving gas
any electrical work, including a new circuit if the switchboard needs one
a tempering valve and the pipework changes for a new tank position
a base or pad for the unit, and the outdoor position that keeps noise away from bedrooms
every rebate as its own line, with the model's certificate count, so you can see what was assigned to the installer

Two installers quoting the same model can differ by more than the rebate. That is why PumpSwap sends your request to up to 3 local installers rather than showing one price.

The downsides, in Queensland

Noise. The outdoor unit is a small compressor and fan, and each brand's quietest model is rated between 37 dB and 50 dB, on the makers' own figures. It runs in bursts to reheat the tank, so position it away from bedrooms and a neighbour's windows, and set it to run in the day if you have solar. Queensland's Environmental Protection Act 1994 treats a heat pump as a pump (section 440T): no audible noise at a neighbour's premises before 7am or after 10pm, no more than 5 dB(A) above background from 7am to 7pm, and no more than 3 dB(A) above background from 7pm to 10pm. That is stricter than the air conditioner rule usually quoted. Queensland legislation, Environmental Protection Act 1994

Recovery time. A heat pump reheats a tank more slowly than gas, which is why sizing matters: a 270L or 315L tank suits most three to four person homes, and larger homes go bigger rather than relying on the boost element.

Cold nights. In cold weather the unit draws less heat from the air and works harder, and many models switch on an electric boost element on the coldest nights, so winter running costs sit above the annual average. In July, usually the coldest month, Brisbane averages a minimum of 10.5°C at the Bureau of Meteorology's Brisbane station, and in January a maximum of 30.4°C. A heat pump runs near its best efficiency almost all year.

Water quality. Urban Utilities describes South East Queensland's water as hard to moderately hard, and publishes no single figure, so check the tank warranty's water quality conditions before you buy. Urban Utilities, water hardness

Space. Most units are a single tank with the heat pump on top, taller than the gas or electric tank they replace; split systems put the compressor beside the tank and need a little more room.

Who can install a heat pump in Queensland

In Queensland a solar or heat pump hot water system must be installed by a hot water installer with a solar and heat pump endorsement from the Queensland Building and Construction Commission. A plumber's restricted electrical licence covers work on hot water systems but not electrical installation work, which needs a licensed electrician.

Queensland heat pump questions

Is a heat pump hot water system worth it in Queensland?

How much does a heat pump cost installed in Brisbane?

PumpSwap's modelled installed price after rebates in Queensland is $2,300 - $4,800, and across 224 Queensland suburbs it runs from $2,200 - $4,900. The brands sold here start from $2,500 installed before rebates. The exact price depends on the model, your home and the installer, which is why we show quotes rather than one number.

What heat pump rebates are available in Queensland?

Does a heat pump hot water system work in Brisbane's winter?

Yes. In cold weather a heat pump draws less heat from the air and works harder, and many models switch on an electric boost element on the coldest nights, so winter running costs sit above the annual average. In July, usually the coldest month, Brisbane averages a minimum of 10.5°C at the Bureau of Meteorology's Brisbane station, and in January a maximum of 30.4°C. A heat pump runs near its best efficiency almost all year. Heat pumps also earn more federal certificates in colder climate zones, because they displace more electric heating there.

How noisy is a heat pump hot water system?

Across the brands sold in Queensland, each brand's quietest model is rated between 37 dB and 50 dB, on the makers' own figures. Makers measure at different distances, so treat the numbers as a guide rather than a like-for-like ranking. The outdoor unit runs in bursts, mostly when hot water is being reheated, so where it sits and when it runs matter more than the number. Queensland's Environmental Protection Act 1994 treats a heat pump as a pump (section 440T): no audible noise at a neighbour's premises before 7am or after 10pm, no more than 5 dB(A) above background from 7am to 7pm, and no more than 3 dB(A) above background from 7pm to 10pm. That is stricter than the air conditioner rule usually quoted.
