Heat Pump install

Are you thinking about purchasing a heat pump for your Dunedin home? Heat pumps are an efficient and cost-effective way to keep your home at a comfortable temperature. But before you buy one, it’s important to ask yourself some key questions to make sure you’re getting the best heat pump for your needs.

What size heat pump do I need for my Dunedin home?

Heat pumps are an increasingly popular choice for Dunedin homeowners looking for an efficient and cost-effective way to heat and cool their homes. But before you install a heat pump, it’s important to understand the different sizes available and how to determine the size that is right for you.

The size of the heat pump you choose is based on the size of your home, how well insulated it is, and the climate in your area. Generally, the larger the home, the larger the heat pump you will need. To determine the best size for your home, you should start by calculating the total square footage of your home. Then, you will need to factor in the climate and insulation level of your home.

In cooler climates like in Dunedin, a larger heat pump may be needed to heat the home efficiently. This is because the larger heat pump will have the capacity to move more air through the home, allowing it to heat the home more effectively. In warmer climates, a smaller heat pump may be sufficient, as the higher insulation levels and warmer temperatures will require less energy to heat the home.

You should also consider the type of heat pump you are looking to install. If you are looking for a quieter operation, then a ductless mini-split system may be the best choice. This type of system operates with two separate components, one outside and one inside, and provides quiet and efficient heating and cooling.

When you are ready to purchase a heat pump, it is important to consult a qualified HVAC technician to determine the correct size for your home. We will be able to assess your home’s needs and recommend the best size for your needs.

No matter which size heat pump you choose, it is important to ensure it is properly installed and maintained to ensure it functions optimally. A well-maintained heat pump can provide years of reliable and efficient heating and cooling.

What type of system should I buy?

Heat pumps come in several different varieties, all of which have their own advantages and disadvantages. The most common type is an air-source heat pump, which uses the outdoor air to heat and cool your home. This type of heat pump is efficient, but it is not suitable for cold climates, as it can struggle to heat your home in temperatures below freezing.

There are also ground-source heat pumps that use the ground to heat and cool your home. These systems are much more efficient than air-source heat pumps, as the ground remains a consistent temperature year-round. Generally this system is used in the commercial space rather than residential homes. This is due to the cost associated with installing one. Ground-source heat pumps require a lot of land space to install, making them more expensive from the extra hours required to install one.

In New Zealand, ground source heat pumps are rarely used and therefore the more common seen type of heat pump is an air source unit. This is backed by McClelland heat pump specialists who recommend air-source heat pumps for residential homes. When deciding which type of heat pump system to buy, you should consider the size of your home, the climate you live in, and your budget.

What control options are available?


The most common type of control for a heat pump is a thermostat. This device measures the temperature in your home and adjusts the heat pump’s output accordingly. It also allows you to set a desired temperature and the heat pump will keep your home at that temperature. Thermostats come in various types and can be either wall-mounted or wireless, depending on your preference.


Another option is a timer. This allows you to set a schedule for when your heat pump should turn on and off. This can be useful if you want to only heat your home at certain times of the day, or if you want to turn off the heat pump at night to save energy. Timers are usually wall-mounted and can be programmed to turn on and off at specific times.

Remote control

The last option is a remote control. This is a device that allows you to control your heat pump from anywhere in the house. It is especially useful if you have a large home or multiple rooms that require different temperatures. With a remote control, you can simply adjust the temperature in each room without having to get up and reset the thermostat.

How do I identify an energy efficient heat pump?

If you live in New Zealand and are looking for an energy-efficient heat pump for your home, there are a number of factors to consider. Heat pumps are one of the most efficient ways to heat and cool your home, but not all heat pumps are created equal. Here are some tips to help you identify an energy-efficient heat pump in New Zealand.

Check the Energy Rating Label

The best way to identify an energy-efficient heat pump in New Zealand is to look for the Energy Rating Label. This label, which is required by law, gives you an indication of the energy efficiency of the heat pump. The label will give you an energy efficiency rating, which is measured on a scale from one to ten, with ten being the most energy efficient. 

You should also check the energy consumption rating, which is measured in kilowatt-hours (kWh) per hour. The lower the number, the more energy efficient the heat pump is.

Look for Heat Pump Features

When you’re looking for an energy-efficient heat pump, you should also consider the features that the heat pump has. Many heat pumps now come with features such as variable speed fans and compressors, which can help reduce energy consumption. 

You should also check to see if the heat pump has a timer setting, which can help reduce energy consumption by only running the heat pump when it’s needed.

Consider the Brand

It’s also important to consider the brand of the heat pump you’re looking at. Different brands have different levels of energy efficiency, so it’s important to do your research and find out which brands are the most energy-efficient. Some brands are more well-known for their energy efficiency such as Fujitsu Heat pumps

Get a Professional Assessment

Finally, it’s a good idea to get a professional assessment from a qualified technician. Call us and we will be able to assess your home and recommend the best heat pump for your needs. We will also be able to provide expert advice on how to get the most out of your heat pump and keep it running at its most energy efficient.

How long is the warranty?

Heat pumps are a major investment for any homeowner, so it’s important to understand the warranty that comes with them. Fortunately, most heat pumps come with some type of warranty that covers the cost of repair or replacement should something go wrong in the future. The length of this warranty varies depending on the type of heat pump and the manufacturer, but there are some general guidelines to keep in mind.

For most basic models of heat pumps, the typical warranty is between five and ten years. This covers both parts and labour and is usually good for any kind of malfunction that is not caused by improper installation or use. For example Fujitsu General New Zealand provides a 6 year full parts and labour warranty for all residential heat pump / air conditioning systems installed through a Fujitsu Accredited Installer.

In addition to the length of the warranty, it’s important to read the fine print. Many manufacturers will also offer a warranty on specific components, such as the compressor or fan motor. These warranties may be shorter than the overall warranty and may only cover certain types of repairs or replacements. It’s important to know what is covered and what isn’t so that you can make an informed decision when purchasing a new heat pump.

When it comes to warranties, it’s always a good idea to do some research before making a purchase. Reading reviews and asking questions about the warranty coverage can save you a lot of time and money in the long run. Ultimately, knowing the length of the heat pump warranty can make the difference between a lasting investment and an expensive repair.


When it comes to buying a heat pump, it’s important to do your research and ask the right questions. Knowing what to look for in a heat pump and understanding how the system works can be the difference between a successful purchase and a costly mistake. 

Asking questions about the type of heat pump you need, the size of the unit, installation costs, energy efficiency ratings, and warranties can help you make an informed decision. With the right information, you can confidently select the best heat pump for your home.
