At G Store, we get a significant number of customer enquiries each week from people looking to:

  • Reduce gas and electricity bills
  • Replace underperforming, broken products and systems
  • Create a more cost-effective and sustainable home

When it comes to taking the first steps towards a home that is more energy-efficient, it’s hard to bypass the heat pump: a stunning piece of contemporary, energy-efficient technology​​ that transfers heat from one location to another, using only a very small amount of energy to do so. 

More generally, heat pumps are most commonly used for heating and cooling homes and buildings, as well as for heating water for use in the domestic setting. But why have heat pumps become so popular? By transferring heat from the surrounding air into a water storage tank, heat pumps can help you:

  • Increase your energy-efficiency: Heat pumps are more energy-efficient than traditional heating and cooling systems, resulting in lower energy bills and reduced greenhouse gas emissions
  • Provide super low-cost heating and cooling: Heat pumps eliminate the need for separate systems and reduce upfront costs
  • Increase the lifespan of your systems: Heat pumps have a longer lifespan than traditional systems, resulting in fewer replacements and lower overall costs over time

To understand how these incredible systems work, we’re going to take a look at three key areas of knowledge, including:

  • How heat pump technology functions
  • The benefits of heat pump hot water systems
  • How to decide which system is best for you

Ready? Let’s get into it.

How heat pump hot water systems work

Heat pump hot water systems work via a broadly six-step process:

  1. The pump system absorbs heat from the surrounding ambient air and transfers it to a water storage tank
  2. The process then begins with a fan drawing in air from the surrounding environment and directing it across an evaporator coil
  3. The refrigerant in the coil then absorbs the heat from the air, which then changes the refrigerant from a liquid to a gas
  4. The gas is then compressed, which causes it to release the absorbed heat
  5. The heat is transferred to the water storage tank via a heat exchanger, which heats the water to the desired temperature
  6. Finally, the gas then reverts to a liquid state and is circulated back to the evaporator coil to repeat the process

Traditionally, most hot water systems in Victoria are either gas or electric. When compared to gas/electric systems, heat pump hot water systems prove vastly superior in terms of their overall energy-efficiency, effect on your electricity/gas bills, and safety/kindness to the environment. They can, in fact, be up to 65% more energy-efficient than electric systems and up to 35% more efficient than gas systems.

This means that for the same amount of hot water, a heat pump system uses considerably less energy compared to a gas or electric system. This translates to lower energy bills and reduced greenhouse gas emissions, making heat pump hot water systems a more environmentally friendly and cost-effective option in the long run.

Benefits of heat pump hot water systems

By now, you’ve probably gathered that heat pump hot water systems have a number of major benefits over both gas and electric hot water systems. Let’s look at a few of these in detail.

  1. Energy-efficiency

As we’ve already recounted, heat pump hot water systems are known to be up to 65% more energy-efficient than electric systems and up to 35% more efficient than gas systems.

Pair a high-quality heat pump hot water system with a new solar PV system and solar battery storage, and you’ve got yourself one heck-of-a-system that is not only going to save you money, but potentially make you money in the long run.

  1. Lower greenhouse gas emissions

In addition to being energy-efficient, heat pump hot water systems also produce fewer greenhouse gas emissions compared to traditional systems. 

According to a report by the Australian government’s Department of the Environment and Energy, heat pump hot water systems emit 75% less greenhouse gas emissions than electric systems and 57% less than gas systems.

  1. Longer lifespan

Heat pump hot water systems also have a longer lifespan than traditional systems. 

According to the Sustainable Energy Authority of Victoria, heat pump hot water systems have a lifespan of around 15 years, compared to 10-12 years for electric systems and 8-12 years for gas systems.

Which heat pump is right for me?

At G Store, we’re proud to stock several high-quality heat pump options including those from:

  • Reclaim Energy
  • EVO
  • Sanden 
  • Apricus

We do all the hard work for you, hand-selecting only the best-quality pumps that will keep your systems cost-effective and working to their best capacity for years to come. Some of the most important questions to consider when you’re choosing a heat pump for residential applications include:

  • Size and capacity needs
  • Location and installation requirements
  • Energy efficiency
  • Brand and quality
  • Balancing upfront and ongoing costs
  • Climate-related needs

Of course, the very best decision you can make when choosing to go with heat pump hot water systems is to speak with an experience, licensed professional retailer/installer so you can understand the options best associated with your needs.

Wrapping up

Heat pump hot water systems offer a cost-effective and energy-efficient alternative to traditional electric and gas-powered systems. By absorbing heat from the surrounding air, heat pump hot water systems can provide hot water for domestic use with fewer greenhouse gas emissions and a longer lifespan. 

As energy efficiency and sustainability become increasingly important issues, heat pump hot water systems are likely to become an even more popular choice for Australian households.
