Tired of your energy bills eating up your budget? With living costs on the rise, looking for ways to cut expenses makes sense. One easy way to save? Upgrading how you heat your water.

An energy-efficient heat pump will be your new best friend. These clever systems use far less electricity than traditional water heaters, giving you hot water when you need it and savings where you want them—your electricity bills.

At iStore, we’re all about helping you heat your home’s water affordably and sustainably because we believe comfort shouldn’t come at a high cost to your family or the environment.

Benefits of Energy-Efficient Heat Pumps

Energy Savings

Energy-efficient electric heat pumps are about three times more efficient than conventional electric water heaters. Instead of constantly burning through electricity, they use smart technology to heat your water, saving you money on electricity bills. These savings really add up over time.

The best energy-efficient heat pumps feature economical operating modes to save you even more money. 

For example, an eco mode for everyday use keeps energy consumption low while providing reliable hot water. Another popular mode is the vacation mode, which maintains the tank’s temperature just enough to avoid issues like freezing or bacterial growth without wasting energy while you’re away. 

Environmental Benefits

Choosing an energy-efficient heat pump isn’t just good for your wallet—it’s great for the planet, too. 

A heat pump uses less electricity than an electric water heater because it transfers thermal energy from the air rather than generating heat directly. As this process relies on air—a renewable energy source—instead of fossil fuels, your home’s greenhouse gas emissions and carbon footprint are reduced.

What Our Clients Have To Say

Here’s what just a handful of customers have to say about their iStore heat pump.

“Great, affordable unit. Had a 180L iStore heat unit installed to replace our old instant gas unit. Easy-to-use unit with good energy-saving features. Heats water and holds heat efficiently.”

Samuel B.

“We had the iStore 180L heat pump installed a couple of months ago and are more than happy with its performance. For a two-person household, this hot water service has consistently delivered hot water. Given that we have solar, we run the heat pump during the day, with the water set to heat between 10 am and 3 pm, so the cost is minimal.” 

Pia Jess, Adelaide, SA  

“Amazing product. The iStore unit is very energy-efficient and works perfectly. Customer support after purchase was very prompt. Highly recommend if you need to replace a hot water unit. Quiet and efficient.”

Will

“Very efficient unit! The controls are great, allowing me to time the running time to solar hours so that I get free hot water. There’s also a “holiday mode” to stop the unit from heating when you’re away! I’ve got a household of four (no teenagers yet!) but have never run out of hot water with the 180L.”

Jaytee, ACT

“Didn’t know what hot water was till I got an iStore! I recently purchased the iStore after reading all the fantastic reviews online, and I’m so glad I did! The product is amazing, and I didn’t realise how bad my previous hot water system was till I bought the iStore. The installation and ordering were super quick and easy. I will be recommending this product to all my friends and family.”

Taylah, Perth, WA

How Air-Source Heat Pumps Work

Air-source heat pumps pull heat from the air to heat water. Unlike conventional water heaters, which use electricity to generate heat, energy-efficient electric heat pumps use electricity to move heat from one place to another. This process requires much less electricity. 

Here’s a simple breakdown:

1. The system draws in warm air using a fan.
2. The air passes over a coil filled with a special fluid called refrigerant.
3. The refrigerant absorbs the heat from the air and turns into a gas.
4. A compressor pumps the gas, making it hotter.
5. This hot gas transfers its heat to the water in the storage tank.
6. The refrigerant cools down, returns to liquid form, and the cycle starts again.

Choosing the Right Heat Pump for Your Home

How big is your household?

A 180L heat pump is sufficient for the daily hot water needs of one to three people: showers, dishwashing, and light laundry. A 270L size is better suited for the higher demand of four people or more: multiple showers, large bathtubs, and frequent loads of laundry and dishes.

What type of system suits your home?

With a split system heat pump, the tank is installed indoors (e.g., in the garage or laundry), and the heat pump unit is installed outdoors. This setup is ideal if you have limited outdoor space or want to protect the tank from the elements. In contrast, an integrated system is easier to install and reduces indoor operating noise because it’s an all-in-one unit installed outdoors.

How important are energy efficiency and cost savings to you?

Look for a heat pump with a high energy-efficiency rating to cut down on electricity bills and save you money in the long run.

What’s the climate like where you live?

If you live in a colder area, choose a heat pump specifically designed to perform well in low temperatures.

How well-insulated is the tank?

Choose a tank with good insulation to keep water hot for longer and reduce the heat pump’s workload.

Will you pair your heat pump with solar panels?

Check that your roof has enough space and gets plenty of sunlight to make the most out of your solar panels and, in turn, your energy-efficient heat pump.

Rebates and Incentives

State-Based Savings

Some Australian state governments offer incentives and rebates if you install solar panels, solar batteries, and heat pumps. 

You may be eligible for $800 to $3,000 off a renewable energy hot water system when replacing a traditional system. You could receive a $1,080 rebate just for installing an iStore 270L heat pump, as it’s approved by the Australian Federal Government Clean Energy Regulator.

In NSW, incentives range from $1,600 to $2,400 off the upfront installation cost of a household solar battery for homes with existing solar systems. The excess solar energy stored in this battery can power your heat pump.

In Victoria, eligible households can receive a rebate of up to $1,400 for installing solar panels. Using solar panels to power your heat pump will reduce your reliance on the grid and your water heating costs. 

Federal Incentives

The Federal Small-Scale Renewable Energy Scheme (SRES) is an Australian government initiative encouraging households and small businesses to install renewable energy systems, such as solar panels, solar hot water systems, and heat pumps.

Under this scheme, when you install an eligible system, you receive Small-Scale Technology Certificates (STCs), which can be sold to lower the upfront cost of your system. The number of certificates you receive depends on your system’s size, location, and the amount of renewable energy it’s expected to generate or displace over its lifetime.

Electricity tariffs are also available Australia-wide to save households money on their bills, but the types and structures of tariffs vary depending on the state, territory, and energy provider.

One such tariff is the time-of-use tariff. Electricity rates vary depending on the time of day, with lower rates during off-peak hours. You can reduce energy expenses by scheduling your heat pump to operate during these cheaper periods. 

FAQs

What Government Incentives Are Available for Installing Heat Pumps?

Under the Federal Small-Scale Renewable Energy Scheme (SRES), households installing eligible renewable energy hot water systems can create Small-Scale Technology Certificates (STCs). These STCs can then be sold to recover a portion of the upfront system installation cost.

On a state level, homes may be eligible for $800 to $3,000 off a renewable energy hot water system when replacing a traditional one. 

How Do Energy-Efficient Heat Pumps Impact Home Resale Value?

Energy-efficient heat pumps can increase home resale value by appealing to buyers looking for lower energy bills, modern technology, and sustainable features.

How Do I Choose the Right Size Heat Pump for My Home?

What Is a Heat Pump System?

Unlike traditional electric heaters, which use electricity to generate heat, or gas heaters, which burn fuel, heat pump water heater systems draw thermal energy from the air to heat water.

Since air is a limitless resource, using it to heat water is a smart, sustainable choice that reduces energy use and costs.

How Does a Heat Pump Heater Work?

1. A fan pulls in air across the heat pump’s evaporator. 
2. Refrigerant in the evaporator absorbs thermal energy from the air. This energy causes the refrigerant to heat up and change from a liquid to a gas. 
3. The compressor then pressurises this gas, making it hot.
4. The hot gas travels through a condenser coil, which heats the water inside a coil-wrapped tank.
5. Once the gas cools down, it turns into a liquid and returns to the evaporator to start the process again.
6. The cycle continues until the set target temperature is achieved.
7. As customers use hot water in their homes, the cycle restarts once the tank temperature drops below a certain temperature.

Exploring iStore’s Product Range

The iStore 180L heat pump is ideal for smaller households with up to three people, efficiently handling daily showers, regular dishwashing, and small laundry loads.

Choosing the Right Heat Pump

Household Size and Hot Water Usage

Here are key factors to consider when recommending a heat pump heater to your customers.

• Smaller Households (1–3 people): For homes where daily use includes a couple of showers, washing dishes, and light laundry, a 180L heat pump is a great choice. It meets typical demands without overspending on capacity.
• Larger Households (4+ people): If your customer’s family takes back-to-back showers, fills larger bathtubs, or runs frequent loads of laundry and dishes, go for a 270L model. It can keep up with heavier hot water needs, so no one has to face the dreaded cold last shower of the day. 
• Future-Proofing: Is your customer’s household small now but could potentially grow later? A bigger system can save them from needing a future upgrade.

Climate Compatibility

It’s important to take into consideration where your customer lives because although heat pump water heaters are suitable for various climates, their efficiency can change depending on the temperature. 

Standard heat pumps work well year-round in mild to warm climates with temperatures consistently above 5°C. They pull enough heat from the air to meet daily hot water demands without extra assistance.

In areas where temperatures regularly drop below 5°C, you’ll want a heat pump with these features.

• Defrost Function: Prevents ice build-up on the evaporator, ensuring the system runs smoothly even in freezing conditions.
• Boost Mode or Backup Element: A supplementary heating element helps maintain water temperature when the air is too cold for the heat pump to operate effectively.
• Insulated Tank: Better insulation keeps the water hot for longer, reducing the system’s workload.

Plumbing Considerations

Sacrificial Anode

After installing an iStore heat pump, it’s a good idea to explain the system’s sacrificial anode to your customer. You can tell them how this metal component in the system’s water tank attracts corrosive elements in the water, preventing them from attacking and corroding the tank.

Each iStore heat pump heater has two sacrificial anodes: the whole life anode, which stays in place for the system’s entire lifespan, and the service anode, which must be replaced. 

If the customer’s home uses capital city water, you should replace the service anode every five years. More frequent checks and replacements are necessary for harsher regional water usage.

Scaling Protection

Your customers must understand that minerals found in hard water, such as calcium and magnesium, can build up inside their systems, forming scale deposits on heating elements and internal components. 

Scaling can make it harder for the heat pump to transfer heat to the water, increasing energy use and running costs. Excessive scale can lead to clogged pipes, damaged components, and even system failure, resulting in costly repairs or replacements.

Educating your customers on scaling protection measures, like installing a water softener in hard water areas or scheduling regular maintenance, will save them money on energy and repairs and extend the life of their heat pump water heater.
