Heat Pump Installation Process: A Step-by-Step Guide

Heat Pump Installation Process A Step-by-Step Guide

A heat pump hot water system is an energy-efficient technology designed to heat water for domestic use, such as bathing, showering, dishwashing, and space heating. It operates on transferring heat from one place to another, making it highly efficient compared to traditional electric water heaters. 

In Australia’s harsh climate, a heat pump is a necessity. Thus, we bring you our blog on the entire heat pump installation process. It is a step-by-step guide for you to start the journey of installing heat pumps in your home. 

Before that, here are the basic functionality of a heat pump.  

Heat Pump Functionality

Heat Absorption: The system contains a heat pump unit connected to a tank that holds the water to be heated. The heat pump absorbs heat from the surrounding air, even when the air is relatively cool. 

Heat Exchange: The absorbed heat is transferred to a refrigerant fluid inside the heat pump. The refrigerant evaporates as it absorbs the heat. 

Compression: The heat-laden refrigerant gas is then compressed, significantly raising its temperature. 

Heat Transfer: The high-temperature refrigerant gas is passed through a coil or heat exchanger inside the water tank. As the hot gas circulates through the coil, it releases its heat to the water, raising its temperature. 

Condensation: After releasing heat into the water, the refrigerant gas condenses back into a liquid form. 

Repeat Process: The cycle then repeats as the heat pump continues to absorb heat from the surrounding air and transfer it to the water until the desired water temperature is reached. 

Hot Water System Installation Regulations

Various standards and codes govern the installation regulations for hot water systems in Australia. It’s important to note that regulations can change over time. So you should check with your local authorities and relevant regulatory bodies for the most up-to-date information.  

Hot water system installations in Australia are regulated primarily by the Plumbing Code of Australia (PCA), part of the National Construction Code (NCC). The NCC is updated every few years, and the latest version should be consulted for the most current regulations. 

Any person or business installing hot water systems must hold the appropriate plumbing and gas fitting licences issued by the relevant state or territory authority. These licences ensure that individuals are qualified to perform the work safely and comply with regulations. 

Hot water systems must comply with Australian Standards (AS). The specific standard that applies will depend on the type of system. Backflow prevention devices may be required depending on the type of hot water system and its connection to the main water supply.  

Hot water systems have energy efficiency requirements, especially for new installations. Compliance with these requirements may be mandatory to meet environmental and energy-saving goals. 

Specific regulations apply to installing solar hot water systems, including collector location, sizing, and plumbing connections. These systems are also eligible for government incentives and rebates in some cases. 

The Energy Savings Scheme (ESS) may help you replace an older, less efficient electric or gas water heater with a more efficient heat pump water heater. The ESS provides financial incentives that allow you to get a discount on the cost of your installation. 

Always consult with an expert installer to ensure that your hot water system installation complies with the latest regulations in your area. 

How To Install Heat Pump Hot Water System

The installation process of a heat pump in Australia involves several steps to ensure efficient and effective heating and cooling for residential or commercial spaces. Please note that the specific details and requirements may vary depending on the type of heat pump (air source or ground source) and local regulations. Here’s a detailed overview of the typical heat pump installation process in Australia: 

Initial Assessment and Planning

Initial planning will start with selecting expert installers and getting multiple quotes. Your installer will suggest the perfect plan based on your specific situation. They might ask for your site’s picture or come for a site assessment.   

The installer will also check for any existing heating or cooling systems that need to be removed or integrated into the new system. You might also need to change or upgrade your old meter. Your installer will let you know about it after the initial assessment.   

Selecting the Heat Pump Type

Two common types of heat pumps are air source and ground source (geothermal). The choice depends on space availability, budget, and local climate. Smart Lifestyle Australia uses air-source heat pumps because they are the most energy-efficient.  

Permit and Approval

Standard heat pump hot water system usually comes with different capacity models. Smart Lifestyle Australia has four capacity models. You can use the 150 and 200 litres with small appliances. And 200 litres are for one to four people. Lastly, 300 litres are for four or more people.   Proper sizing is critical to ensure the heat pump operates efficiently. If the system is too small, it will struggle to heat or cool the space; if it’s too large, it can lead to energy wastage. Check out our heat pump page to have the information in detail.  

Heat Pump Capacity

Depending on the location and type of heat pump, local permits and approvals may be necessary. The installer will handle the paperwork and ensure compliance with local regulations.

Suitable Location

The outdoor unit is typically installed on a concrete pad or brackets for air source heat pumps. The indoor unit is installed in a suitable location inside the building. 

For ground source heat pumps, a loop system is buried underground. This can be a horizontal or vertical loop, depending on available space and geological conditions. 

Refrigerant and Electrical Connections

The installer will connect the heat pump unit to the refrigerant lines and electrical supply. This step requires precision to ensure proper refrigerant flow and electrical connections. 

Testing and Commissioning

After installation, the heat pump system undergoes extensive testing to ensure it operates as intended. This includes checking refrigerant levels, airflow, and electrical connections. 

The installer will also program the thermostat and explain its operation to the homeowner or building owner. 

Insulation and Sealing

Proper insulation and sealing are crucial for heat pump efficiency. Installers may recommend or carry out additional insulation work to reduce heat loss and gain. 

Safety and Compliance

The installation must meet all safety and compliance standards, including electrical and refrigeration codes. 

Training and Handover

The installer should provide training to the occupants on how to operate and maintain the heat pump system. They will also leave behind documentation, including user manuals. 

Regular Maintenance

Periodic maintenance is essential to keep the heat pump operating efficiently. It may include cleaning filters, checking refrigerant levels, and inspecting electrical components. 

Proper installation by qualified professionals maximises the heat pump system’s efficiency and lifespan while ensuring the property’s comfort and energy savings. 

Warranty For Hot Water System

energy efficiency

Warranty terms can vary depending on the manufacturer, model, and the specific dealer or installer you purchase the heat pump from. Warranties typically range from 2 to 5 years for essential parts and labour.  

However, some manufacturers may offer extended warranties for specific components, such as the compressor. Smart Lifestyle Australia offers a 5-year warranty, the highest compared to the market.  

Pay attention to the terms and conditions, what is covered, and for how long. Some installers may offer their warranties on top of the manufacturer’s warranty, so it’s also a good idea to inquire about this. 

Since warranty terms and conditions can vary between manufacturers and suppliers, contact manufacturers for the most up-to-date information on heat pump warranties in your region. Be sure to ask for written documentation of the warranty terms.
