Heat Pump Installations: Why Smart Mounting Options Matter

When it comes to pool heating, heat pumps are one of the most popular and energy-efficient options available. But what many pool owners don’t realise is that how a heat pump is installed can be just as important as the unit itself.
Every backyard, equipment area and pool setup is different which means there’s no such thing as a one-size-fits-all heat pump installation. To show just how flexible heat pump solutions can be, we’re sharing three recent installations completed by our technicians. Each one has carefully considered the space and requirements of the individual client to ensure customer satisfaction and optimal efficiency.
Vertical Discharge Installation
In this installation, our technician recommended a vertical discharge heat pump, where the cool air is expelled upward rather than out the side of the unit.
Correct airflow is critical for heat pumps to operate efficiently, so accurate measurements were taken to ensure the required clearances were met in line with the manufacturer’s specifications. In this case, the vertical discharge design worked particularly well because it prevented cold air from blowing across a nearby pathway and onto a hedge.
Another advantage of this setup is that vertical discharge units generally require less clearance in front of the unit making them well suited to tighter equipment areas. As long as there are no overhead obstructions, positioning is usually straightforward.
The ground was already level so the unit was installed on purpose-made polyslabs with anti-vibration feet, helping to minimise any potential movement or noise. Like most heat pumps, the system required a dedicated electrical circuit which must always be installed by a licensed electrician.
From a plumbing perspective, heat pumps don’t need large volumes of water flow. To manage this correctly, our technician installed a bypass valve after the filter and reintroduced the water before the chlorinator, ensuring the heat pump received the correct flow without affecting overall circulation.
Overall this installation highlights how vertical discharge units can be a less obtrusive option when airflow direction and clearances are a concern.


Wall-Mounted Side Discharge
For this job our technician installed a side discharge heat pump mounted on wall brackets, lifting the unit above a garden bed and freeing up valuable ground space.
Plumbing and electrical considerations were similar to the vertical discharge setup, but wall mounting offered added flexibility where ground space was limited.
The unit was mounted using manufacturer-supplied wall brackets securely fixed to a solid brick wall with concrete anchors. While heat pumps operate quietly, rubber mounting feet were used to minimise vibration and ensure long-term stability.
One practical benefit of wall mounting is condensate management. Heat pumps naturally produce condensation, and in this case wall mounting made it easy to direct condensate safely into the garden bed to prevent pooling around the equipment area.
This installation is a great example of how wall-mounted options can help overcome space and layout challenges without compromising performance.


Floor-Mounted Side Discharge
This installation formed part of a complete pool equipment upgrade during a major backyard renovation.
The client replaced their entire system including a variable speed pump, media filter, chlorinator and heat pump after their existing solar heating was no longer operational. With plans to move to solar PV (electrical panels) in the future, a heat pump offered a flexible and efficient heating solution.


Because the ground was sloping, the client prepared the area using crushed rock for drainage and concrete paving slabs to create a stable, level base for all equipment. Having a clean slate allowed our technician to configure and position everything in the most practical and efficient layout possible.
Pool heat pumps must be sized based on several factors including pool volume, usage and desired water temperature. After discussing these considerations with the client, a side discharge unit was selected and positioned so the discharge air flowed away from living areas.
While this wasn’t the simplest installation, it demonstrates the advantages of designing an equipment setup from the ground up rather than working around existing limitations.


The Key Takeaway
While all heat pumps share similar requirements such as correct water flow, adequate airflow clearance and a dedicated electrical supply, the way they’re installed can vary greatly depending on the space.
Vertical discharge, wall-mounted side discharge and floor-mounted side discharge installations each offer unique benefits. The right choice comes down to understanding the site, the customer’s goals and how the equipment will interact with the surrounding area.
