Frequently Asked Questions (FAQ)

Thil Bandara

We replaced our gas water heater with a heat pump solution. Luke and his team were fantastic from initial chat to installation. One of the amazing things I found was during our initial chat I mentioned the use of a different technology and Luke investigated if that was something that was viable for our household instead of ignoring the idea. Even though the installation didn't go according to plan as there was some unexpected issues the team were able to come up with a great solution to get the job done in the end. Would highly recommend them.

We have used Luke and his team twice for different issues, and both times they have gotten back to us very quickly, continued with great communication, and provided friendly and thorough service. If we have had any issues, they have come back quickly. Can highly recommend Gaschill, and will definitely use them again.

What is a hot water heat pump?

A heat pump is a water heating system that transfers thermal energy between spaces instead of generating heat directly. A refrigerant uses heat from the air, goes through a compressor to further increase its temperature and transfers heat to the water.

It works like a fridge but in reverse- instead of pumping heat out of a fridge to keep it cool, it pumps the heat from the outside air into a tank of water to make it hot.

It can be 4 times more energy efficient compared to conventional electric hot water systems.

What’s the difference between a heat pump and an electric hot water system?

Heat pumps do not use direct electric elements to heat water, unlike electric hot water systems. This is why heat pumps use up to 75% less electricity than electric hot water systems, saving on household bills and greenhouse gas emissions.

How does a heat pump hot water system work?

Heat pump technology is efficient and draws on outdoor heat. Heat is extracted from the surrounding air through a refrigerant, then compressed to further increase its temperature. The heat is now transferred from the refrigerant to heat water from the mains. Hot water is stored in storage tanks to be used as and when needed, all year round.

How long do heat pumps last?

Heat pumps usually last between 15 to 20+ years, depending on the brand and maintenance.

What are the benefits of a heat pump?

Heat pumps cost less compared to hot water tanks over the long run because they are more energy efficient. Heat pumps pump heat using a compressor and circulating gas refrigerant, which use up to 75% less electrical energy compared to a conventional hot water system.

Heat pumps also have a long lifespan because of their design, which is uncomplicated and does not require too many components. The fewer components involved, the less chance of something going wrong and needing to be replaced.

How many types of heat pump water heaters are there?

There are multiple types, ranging from single outdoor units to split systems (both indoor and outdoor) while others can be retrofitted to your existing hot water tank.

How do I know what type of heat pump to pick?

Our GasChill representatives will conduct an assessment of your requirements and recommend a personalised solution for you.

Can I install a heat pump myself?

Heat pumps need to be installed by an accredited and licensed professional. Unless you have those accreditations, it’s best to leave it to the professionals.

Are heat pumps noisy?

This depends on the brand and model but generally heat pumps make a humming noise similar to an air conditioner. Because of this it is best not to install your heat pump too close to bedrooms or neighbouring houses.

Generally, modern outdoor heat pumps have a sound rating of 60 decibels while some ultra-quiet models can be as low as 18 - 30 decibels.

How often do I need to service my heat pump hot water system?

You should schedule servicing appointments with a professional at least once every year.

How do I maintain my heat pump?

Regularly clean the air vents to make sure that air flow is not restricted by dust particles, leaves or other materials.

Otherwise, refer to your user’s manual for guidance as each manufacturer has specific instructions on how you should be maintaining your heat pump.

Heat pump hot water system contribute a great deal to the environment by reducing carbon footprint. It is the greener way to generate hot water for most Aussie households.

Reduce Your Carbon Footprint And Enjoy Government Rebates

Heat pump technology for hot water heating systems uses an efficient process that draws on ambient heat. The heat is first extracted from the surrounding air and absorbed by a natural refrigerant that is ozone friendly. The refrigerant goes through a compressor which increases its temperature.

It is then passed through a heat exchanger to heat water from the mains. The water is then heated and stored in storage tanks to be used as and when needed, all year round.
