If you are fishing for an energy-efficient solution to heat your water, heat pump systems could be the answer. But how do they work, and are they a good fit for our balmy Queensland climate? Let us explain. 

Living in Brisbane, we are blessed with sunshine and warm days throughout the year. It’s the perfect climate for days at the beach and barbecues at home, but it also presents unique considerations when it comes to our home’s utilities. This includes heating our water.  

While traditional systems like electric or gas water heaters are common, there’s another player swimming in the waters of efficient home heating solutions – the heat pump hot water system.

How Do Heat Pumps Work?

Heat pumps might seem complicated, but they are pretty simple. They operate on a principle like a refrigerator, but in reverse. Instead of removing heat from inside and pushing it out, a heat pump extracts heat from the outside air and uses it to warm up your water. 

Here is a breakdown: 

  1. Evaporation: a heat pump hot water system contains a refrigerant that, when exposed to warm outside air, evaporates, and turns into gas. 
  1. Compression: the refrigerant gas is then compressed, increasing its temperature. 
  1. Heat exchange: this hot gas then flows through a heat exchanger, transferring its heat to the water stored in your tank. 
  1. Condensation: once it loses heat, the refrigerant condenses back into a liquid, ready to start the process again. 

This process allows heat pumps to turn a small amount of electrical energy into a large amount of heat energy. It might seem like magic, but it’s science! 

Are Heat Pumps a Good Fit for Brisbane?

Heat pumps thrive in warm climates, and thankfully, Brisbane fits the bill. With our long, hot summer days and mild winters, heat pumps can operate efficiently all year round. Even if we do get hit with lower-than-average temperatures, we don’t need to worry – heat pump systems can extract heat from air temperatures as low as -7°C. 

If you’re considering a heat pump in Brisbane, just remember that while these systems are energy-efficient, they also rely on electricity to run. Does this make you nervous about higher energy bills? It shouldn’t. Heat pumps use a fraction of the electricity required to heat your water compared to traditional electric hot water units. And, if you have solar power (like many of us Brisbanites do), pairing your heat pump with a solar PV system can offset this cost and further reduce your carbon footprint.

The benefit heat pump hot water units have over solar hot water installations in Brisbane is that even during overcast and stormy conditions your heat pump will continue to deliver hot water. You can have a heavy hot water usage day in any weather and your heat pump hot water unit will still deliver hot water that night and the next morning. You do not need to rely on the availability of the sun to heat your water – it still happens, all while using significantly less energy than a traditional electric hot water system. 

There are more benefits, too. Technological advances mean heat pumps today are quieter than ever before. And with many manufacturers providing warranties for up to 15 years, with proper care your heat pump hot water unit will cut replacement costs over time and deliver water heating savings year after year after year.   

The Final Verdict

So, are heat pumps Brisbane friendly? Are they a good idea? 

Yes! Heat pumps are a great hot water solution in Brisbane. They are energy-efficient, effective in our warm climate, and they can be paired with solar systems for extra savings. If you are looking to reel in your energy costs, a heat pump could be the big catch you’re after! They are good news for your wallet and the environment. 

Don’t just buy any old system though. Make sure you consider your property’s size, layout, and your family’s personal needs when it comes to hot water usage.
