Heat Pump Buying Guide

Whether you are finding yourself wearing extra layers in a bid to battle the freezing southerlies or sweltering on a humid summer’s evening you are probably thinking about buying a heat pump. This article will leave you better informed on the subject of buying a heat pump.

How Does a Heat Pump Work?

As the name suggest a heat pump effectively takes warmth from one location and transfers it to another. The most common analogy used by manufacturers is to compare the heat pump with your fridge. You notice that the back of your fridge gets very warm and this is caused by the evaporator coil extracting warmth from the air inside and transferring it into your kitchen through a condenser coil. So there are two coils working to transfer this heat.

Likewise a heat pump involves two separate units, one on the exterior of your house and one on the inside of your house. In winter the exterior unit draws warmth from the air and transfers it into your home and in summer the reverse occurs.

What are the benefits of a heat pump?

  • Provide value for money as the heat pump provides both winter heating and summer cooling.
  • Improved air quality as the air is filtered.
  • Most efficient form of heating making them very economical to run.
  • Perform the role of a dehumidifier.
  • Easy to use and are able to warm up or cool down a room in minutes.
  • Clean and safe to use compared to alternative heating options.
  • Environmentally friendly due to their high energy efficiency.

What are the main features to look for in a heat pump?

Energy Efficiency

While heat pumps are more energy efficient than other forms of heating not all heat pumps are as efficient as others. Look for the energy efficiency star rating. As the EECA website states “each extra star means an extra 10 per cent or more saving in running costs”. Their website has more information on energy efficiency.

Inverter Technology v Fixed Speed

Heat pumps either have inverter technology or operate on a fixed speeds. So what is inverter technology? The inverter which is built into the outside unit gradually increases its compressor speed to match the indoor heating or cooling conditions. A fixed speed unit will run on full load immediately. Heat pumps with inverter technology have the following advantages:

  • Faster start-up time
  • More energy efficient
  • Quieter
  • Don’t get temperature fluctuations


As part of normal operation heat pumps generate some noise due to the fans on both indoor and outdoor units. It’s worth considering these noise levels both for indoor living and sleeping but also for consideration to neighbours from the outdoor unit. Manufacturers should have this information available.

Heating Performance

In New Zealand you may not experience the extremes of North America or Europe but it pays to check what the outdoor operating temperature range is before you purchase a heat pump. Most go down to -10 or -15°C.

Air purification

For allergy sufferers the quality of the air filtration system will be a primary consideration in your purchase.

Moisture Removal

If dehumidification is an important role for your heat pump ensure that the model you purchase is able to perform this role satisfactorily.

Timer functionality

Sleep modes and timer programmes enable you to come home or wake up to the optimal temperature. Check that the model you are going to purchase offers this functionality.
