How to Choose the Right Heat Pump
Choosing the right type, capacity, and brand of heat pump can be a little overwhelming due to the number of options available. The good news is that Heat Force are Christchurch heat pump specialists, and we can guide you through the decision-making process to ensure you get a heat pump that's just right for you. We'll guide you through the details during a free in-home consultation.
Determine the Right Capacity
Getting the capacity right is probably the most important consideration. If you don't have enough capacity, your heat pump will struggle to deliver the heating required to keep you warm and comfortable. The following table shows some typical heating capacities for various room sizes, but many other factors, such as the number of windows and the level of insulation, need to be considered.
Please note that heat pumps are only designed to heat the room they are located in. If you need to heat more than one room, we'll find a solution for you.
Heat Pump Sizing Guide
Room Area (m2) | 2.4m Stud Height | 2.7m Stud Height |
|---|---|---|
20 | 2.6kW | 3.0kW |
25 | 3.3kW | 3.7kW |
30 | 4.0kW | 4.5kW |
36 | 4.8kW | 5.4kW |
42 | 5.6kW | 6.3kW |
49 | 6.5kW | 7.3kW |
56 | 7.4kW | 8.3kW |
72 | 9.5kW | 10.7kW |

Choose the Right Type of Unit
The next most important consideration is to determine if you need a floor console or a wall-mounted unit.
Floor console machines are designed specifically as a heating appliance but usually cost a little more to purchase, and there may be limitations on where they can be placed.
Wall-mounted systems are very cost-effective and are a more flexible option when it comes to installation.
Ducted and multi-split heat pump systems are also great options depending on your needs.
We'll guide you through the pros and cons of each option to ensure you get a heat pump that is right for you.
Select a Brand and Features
Finally, there is brand selection. With so many brands and models to choose from, this can be a difficult decision to make. Some brands and models have extra features such as 7-day timers, air purifying systems, and intelligent motion sensors, which you may or may not require.
We'll help you choose the brand and model that best fits your needs and explain why a particular heat pump is right for you.
