what is a heat pump? how does a heat pump work?

Heat Pump

A heat pump uses electricity to move heat from one place to another. In winter, it pulls warm air from outside and moves it indoors to heat your home. In the summer, it acts like an air conditioner by moving warm air outside while circulating cool air inside your home.

Can my Heat Pump be used as an Air Conditioner as well?

In short, a heat pump cools and heats your home while an air conditioner just cools. Air conditioners can only pump heat in one direction – inside to outside – while heat pumps pump heat in both directions.

All the heat pumps G-Force sell and install have heating and cooling modes which means your unit can be used all year round to warm your home in colder weather, or as an air conditioner in summer.

Why is it important to have a heat pump in your home?

An extensive report by BRANZ found that heat pumps are highly energy efficient and the most cost effective way to warm your home. However, how you use your heat pump is important as heat pump performance is not a fixed factor and depends on:

– The indoor and outdoor temperatures when it is operating;
– What additional energy use is involved e.g using the defrost option;
– System loading – performance will be reduced if the heat pump only operates in demanding conditions, such as being switched off overnight then used to heat cold rooms on cold mornings.

How do you choose the right heat pump for your home?

Here’s some points to consider when choosing a heat pump for your home:
– Will you use it mainly for heating or cooling or both?
– Does your home already have insulation or is it an older home? If your home doesn’t have insulation (or it’s old) we recommend you start there before installing a heat pump.
– Is it for a single room or a large open plan lounge for example. This will determine the size of the heat pump. And if you’re considering a high wall heat pump unit, you also need to think about the placement of the outside compressor unit.
– Would you prefer to control the unit remotely? Then you’ll need to ensure your heat pump is Wi-Fi enabled.
– Where you live also influences the type of heat pump suitable for your home, for example, coastal regions require protection against corrosion if the unit is outdoors.
– For Rentals, the Healthy Homes standards include minimum requirements for heaters in the main living room.
– Different types of heat pumps:
~~~ Floor console heat pumps: these units sit on the floor and are a good option if you’re tight on wall space.
~~~ High wall/Split system heat pumps: these are the most common units and are mounted on an internal wall. The remainder of the unit is located outside.
~~~ Ducted heat pumps: these systems allow you to heat multiple rooms by distributing the heat via ducts installed in your ceiling.

The G-Force team can advise on the make, model and how powerful the heat pump should be to best suit your needs and budget. For example, using a 3kW heat pump for heating your home 5 hours a day for 180 days per year will cost you between $90 – $150 which is less than $1 a day.

You can check out the EECA’s calculator to get some ideas what a heat pump will cost you based on your usage.

Is installing a heat pump a D.I.Y. project, or does it need to be professionally installed?

You do not need a qualified and registered person to install the heat pump however you do need a certified electrician (licensed electrical worker) to connect the unit to the electrical supply. Once complete, you should receive an Electrical Certificate of Compliance and Electrical Safety Certificate post installation.
