The Magic of a Hot Water Heat Pump

A hot water heat pump works in a similar way to an air conditioning system used for heating your home. By extracting renewable thermal energy from the air, it transfers the heat to the water in the storage tank. This process is powered by electricity.

The great thing about hot water heat pumps is that they offer a higher return on investment. In other words, you get more heat energy from the system than the electricity you put in. For example, if you put in 1 kW of electricity, the heat pump can extract 4 kW of heat energy from the air and transfer 5 kW of heat to your hot water. This high coefficient of performance (COP) makes hot water heat pumps incredibly efficient and cost-effective.

Frequently Asked Questions

Is heat pump hot water worth it?

The low operating costs of heat pump water heaters are a significant advantage over other hot water systems. Despite potentially higher upfront purchase and installation costs, hot water heat pumps can lead to substantial savings on monthly energy bills. These systems energy efficiency, coupled with the ability to extract heat from the surrounding air, often make them a more cost-effective choice over the long term when compared to traditional water heaters. This cost savings is a key selling point for those looking to reduce their household expenses and improve their energy efficiency.

Do heat pump hot water systems work well in hot weather?

If you live in an area with a consistently warm climate throughout the year, a heat pump will function effectively and produce ample heat for your hot water needs. The ambient temperature plays a significant role in the performance of a heat pump water heater. Heat pumps are more effective the warmer the ambient air temp.

Are hot water heat pump systems noisy?

In general, hot water heat pump systems tend to operate quietly, which typically poses no significant problem for most people. These systems emit a regular humming sound which becomes barely noticeable over time. Additionally, you may occasionally hear some intermittent clicking noises as various components within the pump engage and disengage as required. Overall, noise levels are generally minimal and are unlikely to be a disruptive factor for most users. Cheap heat pumps run at 50 decibels and are reasonably noisy. Premium heat pumps are much quieter, running at 37 decibels.

Can hot water heat pumps be used with solar pv?

Absolutely, hot water heat pumps can seamlessly integrate with solar PV systems, offering an environmentally friendly and cost-effective solution. You can synchronise your heat pump’s activity with the peak power generation of your solar PV system during the day. This allows you to maximise the utilisation of your self-generated electricity and further reduce your energy consumption. It’s a great pairing that promotes energy efficiency and sustainability.

Are there rebates for hot water heat pumps?

In South Australia, the Retailer Energy Efficiency Scheme (REES) encourages the adoption of solar hot water heat pumps. In addition to REES, the city of Adelaide provides rebates of up to $1,000 for solar heat pumps within city limits, complementing REES and STC incentives. The South Australian Government offers financial incentives of up to $2,000 (when combined with federal incentives) for the installation of eligible solar hot water heaters or heat pumps. See our rebates page here for more information.

What are the pros and cons of heat pump hot water?


Energy Efficient

Unlike conventional models that need to generate heat from scratch, these heaters harness heat from the ambient air, including waste heat from nearby sources like furnaces.

Environmentally Friendly

Heat pump water heaters don’t generate heat through combustion, eliminating the risk of gas leaks and toxic emissions. They produce fewer greenhouse gas emissions compared to traditional gas water heaters.

Family Friendly

Additionally, these units remain relatively cool on the outside, making them safer for households with pets or children.


Traditional water heaters typically last 8 to 12 years, but well-maintained heat pump water heaters can endure for 10 to 15 years.


Heat pump water heaters operate quietly, offering a peaceful home environment, especially when the water heater is located near living spaces or bedrooms.


Upfront Costs

While heat pump water heaters offer long-term savings through lower energy bills, their initial purchase price can be a deterrent for budget-conscious buyers.

Cold Climates

Heat pump water heaters draw heat from the air, making them highly efficient in warm weather but potentially slower during colder months. Premium heat pumps will operate effectively down to -10 °C. Cheap heat pumps are only suitable for warmer climates


Heat pump water heaters may take longer to heat water compared to conventional models. This delay results from the lower operating temperature of heat pump systems compared to gas or electric resistance heaters. Premium Heat pumps heat water quicker than conventional electric hot water systems

Small Homes

Smaller homes may lack the necessary space for a heat pump water heater, primarily due to the need for a condensation drain or pump. These systems absorb heat from the air, requiring adequate space for optimal performance. For smaller homes we have a solution: by using a smaller capacity tank or more compact models
