Understanding Heat Pumps for Homes

An air-source heat pump pulls thermal energy (heat) from the air outside and uses it to warm water. Even on a chilly day, the air still contains thermal energy because the molecules in the air are constantly in motion, and this motion is what constitutes thermal energy.

Here’s how it works: The heat pump system draws in air and uses a special liquid (refrigerant) to absorb the air’s heat. The liquid then compresses, making it very hot. That heat transfers to the water stored in the system’s tank, which is now ready for use throughout the home.

What’s amazing is that this process involves simply moving existing heat; it doesn’t rely on generating heat from scratch, like traditional water heaters. Because of this, heat pumps use approximately one-third of the electricity of conventional electric water heaters. 

Boost a New Construction’s Value With an iStore Heat Pump

Adding an iStore heat pump hot water system to a new build is a clever selling point because of the following benefits to homeowners. 

Energy Efficiency

The performance of a heat pump is typically measured by its Coefficient of Performance (COP), which is the ratio between how much heat the pump produces compared to the electricity it uses. The higher the COP, the more efficient the system.

When the air temperature around an iStore 180L heat pump is 20°C, it can heat water from 15°C to 60°C with a COP of 4.37. This means that for every unit of electricity the system uses, it produces 4.37 times that amount of heat energy to heat water. The 270L heat pump achieves a COP of 4.82 under the same conditions.

This impressive efficiency translates to real energy savings, with iStore heat pumps consuming 75–85% less electricity than traditional electric and gas water heaters!

Long-Term Savings

Although traditional electric or gas water heaters may be cheaper initially, they have much higher running costs over time because they consume significantly more energy to produce the same amount of hot water as a heat pump. 

With water heating accounting for up to 27% of the average home’s energy bills, these higher running costs can quickly add up!

While an iStore heat pump may have a slightly higher upfront price tag, it’s a long-term game-changer. Our heat pumps can save households around 70% on heating costs, equating to savings of as much as $1,000 a year on energy bills. 

Over time, the savings from lower energy bills will more than cover the heat pump’s initial expense.

Increased Home Value

Homes with sustainable, energy-efficient features like an iStore heat pump often command higher resale prices. The system’s advanced technology and long-term benefits– such as reduced energy bills – make it an attractive selling point for potential buyers. 

An iStore heat pump’s compliance with Australian energy efficiency programs and incentives further solidifies its value in the market, reassuring buyers of its quality and reliability.

Superior Performance

iStore electric heat pumps for homes incorporate smart technology for optimal performance.

• Intelligent Computer Control: The built-in computer monitors all aspects of its surroundings and adjusts the heatpumps performance to match the hot water needs while guaranteeing efficiency and reducing energy waste.
• Scheduling Capabilities: Heating schedules can be set to align with daytime excess solar electricity generation or off-peak electricity rates, maximising energy usage and saving homeowners more on electricity.
• User-Friendly Controls: With the easy-to-use digital display, homeowners can conveniently monitor and adjust system settings.
• Diagnostics and Alerts: Built-in diagnostic tools can quickly detect issues and alerts the homeowner to prevent expensive repairs and keep the system running smoothly.

Our heat pumps are also built with high-quality materials and two key features for long-lasting performance.

An integrated heating coil wraps around the outside of the tank, keeping the heating coil separate from the water and avoiding direct exposure to minerals and corrosive elements.

Our tanks also have anodes—metal rods submerged inside the tank preventing rust and damage to the tank itself. Each tank has not one but two anodes—double the anodes means double the durability!

Gentler Environment Impact

A heat pump reduces a home’s greenhouse gas emissions and carbon footprint by using air—a renewable energy source—instead of fossil fuels.

What kind of a reduction are we talking about?

The iStore heat pump uses approximately only 500-800 watts of energy per hour during the heating process, lowering the average Australian home’s CO₂ emissions by up to 2.9 tonnes a year. 

For perspective, the average vehicle emits about 4.6 tonnes of CO₂ annually, so reducing CO₂ emissions by 2.9 tonnes is like taking a car off the road for six months!

Choosing the Right Heat Pump for a New Home Construction

Consider the following questions to choose the right heat pump hot water system for your client’s home.  

1. How big is the household?

A 180L heat pump is sufficient for the daily hot water needs of one to three people, while a 270L size is better suited for the higher demand of four people or more.

2. What system setup best suits the home?

For easier installation – and installation in smaller backyards or narrow side passages – an all-in-one outdoor system like the iStore heat pump is the way to go. Its modern, compact design also integrates seamlessly into new homes without compromising aesthetics—it’s a win-win!

3. How important are energy efficiency and cost savings to the homeowner?

A heat pump with a high energy efficiency rating will cut down on electricity bills and save them money in the long run.

4. What is the climate?

If the house is in a colder area, choose a heat pump proven to perform well in low temperatures. 

If you’re building in NSW or Victoria, it’s helpful to know that the Australian Clean Energy Regulator (CER) divides Australia into climate zones, offering these colder regions higher rebates for installing energy-efficient systems. 

Additionally, the NSW and Victorian state governments include the iStore heat pump in their ESS and VEU energy-saving programs, proving its reliable performance and efficiency in colder climates.

5. How well-insulated is the tank?

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

To qualify for a government rebate, a heat pump hot water system must meet the Australian Government’s compliance testing for heat loss. With over 50mm of insulation, the iStore heat pump tank meets and exceeds this testing.

6. Will the heat pump be paired with solar panels?

Pairing a heat pump with a solar system reduces electricity costs by using free, renewable solar power to run the pump. 

The home’s roof must have enough space for solar panels and get plenty of sunlight to maximise the panels’ use and, in turn, the heat pump. 

Installation and Maintenance

iStore heat pumps for homes are quick and straightforward for a professional to install.

1. The single-unit design eliminates the need for complex refrigerant piping.
2. The compact system requires minimal clearance and fits in typical residential installation spaces.
3. Standard 20mm inlet and outlet fittings easily connect to existing plumbing systems.

Pre-configured electrical “3pin 10 amp” plug is a simple plug and play installation.

It is important for homeowners to know that regular maintenance will keep their heat pump performing at its best and extend its lifespan. 

Every six months, they should clear away debris around the unit to maintain proper airflow and remove any dust and dirt buildup.

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.

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. The iStore is designed to perform in all climate situations experienced in Australia.

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. The istore meets and exceeds the Australian insulation testing standards.

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 $700 rebate just for installing an iStore 180L or 270L heat pump, as it’s approved by the Australian Federal Government Clean Energy Regulator.

In NSW, incentives are available 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 rebates 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 as well as daytime excess power generation. 

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 rebates for a renewable energy hot water system when replacing a traditional one.

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.

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 0°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 check and if required replace the service anode every two 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.
