Common Problems with Heat Pump Installation and How to Avoid Them

There are a number of potential problems that can occur during the installation of a heat pump in New Zealand. In many cases, these problems can be avoided by hiring a qualified and experienced heat pump installation specialist like Goldstar to carry out the work. However, it is still possible for problems to occur.

This article will outline some of the most common problems that can be encountered during heat pump installation, as well as some tips on how to avoid them.

Faulty Wiring

One of the most common problems that can occur during heat pump installation is incorrect wiring. This can often be the result of a contractor not being experienced in installing heat pumps, or of faulty equipment being used. In either case, it is important to ensure that all wiring is correctly installed before the heat pump is turned on. If there are any loose wires, they should be immediately repaired or replaced.

Refrigerant

Another problem that can occur during heat pump installation is the wrong type of refrigerant being used. This can often happen when a contractor is not familiar with the different types of refrigerants that are available. In some cases, they may use a refrigerant that is not compatible with the heat pump, which can cause damage to the unit. It is important to make sure that the correct type of refrigerant is used, so that the heat pump can operate correctly.

R32 is a newly developed refrigerant with low global warming potential. It is being promoted as a more environmentally friendly alternative to other refrigerants such as R410A.

R32 has a number of benefits over other refrigerants:

  1. Lower Global Warming Potential
    R32 has a Global Warming Potential of just 675, compared to R410A’s GWP of 2088. This means that R32 contributes significantly less to global warming than other commonly used refrigerants.
  2. Improved Energy Efficiency
    R32 has a lower heat capacity than R410A, meaning that it can more easily transfer heat. This results in improved energy efficiency for heat pumps using R32 refrigerant.
  3. Reduced Cost
    R32 refrigerant is less expensive than R410A, making it a more cost-effective option for heat pump systems.
  4. Reduced Installation and Maintenance Costs
    R32 refrigerant is compatible with existing R410A piping and equipment, meaning that there is no need to replace existing equipment when switching to R32. This reduces installation and maintenance costs.
  5. Increased Safety
    R32 is classified as a Group A2 refrigerant, meaning it is not flammable. This makes it a safer option than other refrigerants such as R290 (propane), which is highly flammable.

R32 is a promising new refrigerant with numerous benefits over existing options. It is more environmentally friendly, more energy efficient, and less expensive. It is also safer to use than other refrigerants.

Ventilation

A third problem that can occur during heat pump installation is improper ventilation. This can often happen when the installer does not properly seal all of the ductwork. This can cause the heat pump to overheat, and can also result in the unit being less efficient. It is important to make sure that all of the ductwork is properly sealed, so that the heat pump can operate correctly.

Incorrect Parts

Another potential problem that can occur during heat pump installation is the use of incorrect parts. This can often happen when a contractor is not familiar with the different parts that are available. In some cases, they may use parts that are not compatible with the heat pump, which can cause damage to the unit. It is important to make sure that the correct parts are used, so that the heat pump can operate correctly.

Incorrect Size

Finally, a fifth problem that can occur during heat pump installation is the incorrect size of the heat pump. This can often happen when a contractor is not familiar with the different sizes of heat pumps that are available. In some cases, they may use a heat pump that is too small for the area that it is being installed in. This can cause the heat pump to overheat, and can also result in the unit being less efficient. It is important to make sure that the correct size heat pump is used, so that the heat pump can operate correctly.

There are a few factors you’ll need to consider when choosing the right size heat pump for your home.

The climate you live in

If you live in an area with mild winters and hot summers, you’ll need a different size heat pump than someone who lives in an area with very cold winters and mild summers.

The size of your home

A heat pump that’s too small won’t be able to effectively heat or cool your home, while a heat pump that’s too large will use more energy than necessary.

Bedrooms, offices and tiny homes require smaller heat pumps to be efficient and effective.

The type of heat pump you want

There are two types of heat pumps: air-source and ground-source. Air-source heat pumps are more common and less expensive, but they may not be as efficient in very cold climates. Ground-source heat pumps are more expensive but are more efficient and can be used in any climate.

The efficiency of the heat pump

The most efficient heat pumps have higher Seasonal Energy Efficiency Ratios (SEERs) and Energy Efficiency Ratios (EERs). These ratings will be listed on the heat pump’s label, and the higher the numbers, the more efficient the heat pump.

The noise level

Some heat pumps are very quiet, while others can be quite loud. If noise is a concern, be sure to ask about the noise level of the heat pump you’re considering before you buy it.

The warranty

This doesn’t relate to choosing the size of your heat pump, but it is still important to consider.

Most heat pumps come with a warranty, but the length of the warranty and the coverage can vary. Be sure to read the fine print before you buy to make sure you understand the terms of the warranty.
