Heat pumps are one of the most popular air conditioning options in New Zealand and have been for some time due to their cost-effectiveness and ongoing efficiency for a range of settings and spaces.

As both a heating and cooling solution, heat pumps have an undeniable range of benefits, being able to be used year-round to maintain the desired indoor temperature, and they’re not just popular for residential settings either - they’re also commonly used in commercial and multi-unit settings. 

The home heat pump: how to choose the best option

The first thing to consider is the size of the space and the thermal efficiency of the building. Is it double glazed or single glazed? What is the climate like? Will temperatures depart dramatically from the average across the seasons, or is the house in a more temperate climate? Depending on the ambient temperature desired, these questions will have a significant impact on the best option for your space.

Other things to consider are whether the heat pump will be used in conjunction with other heating methods and whether it is required for whole-home heating or for a single room or space within the house.

Electric heat pumps are known for their efficiency as both a heat pump and a heat pump air conditioner, provided the right size and model is chosen for the right space. Too small and the unit is not likely to be efficient, while too large, and the capacity may be wasted as it won’t be required. 

The modern heat pump system

With technology continues to develop at pace in the heat pump sector, there are now various options to choose from, with one of the most interesting, a single outdoor unit, multi-indoor unit system that allows for just one unit to be outside with up to five indoor units operating from it, saving space and aesthetics in the outdoor area - something that was not possible until recently. 

While heat pumps may not be the best solution for every space, they are generally considered one of the most energy-efficient forms of heating and the designer options are vast - from bespoke colours and finishes to size and form.
