How to Install a Pool Heat Pump: Step-by-Step Guide

From figuring out where to place your pump to handling wiring and commissioning the pump, we’ll cover everything you need to know about pool heat pump installation below - starting with choosing the right heat pump for your specific pool!

Choosing the Right Pool Heat Pump

If you’ve already picked your pump and just need advice on installing it, go ahead and skip down to the next section. Otherwise, consider these factors when choosing your pool heater:

  • Pool Size and Volume: Calculate the volume of your pool to determine the BTU (British Thermal Units) rating needed for your heat pump. A larger pool requires a heat pump with a higher BTU rating to heat the water effectively. Our guide on pool heat pump sizing will help you choose wisely. 
  • Climate: Your local climate influences the efficiency of a heat pump. In cooler regions, you'll need a heat pump with a higher performance rating to operate effectively.
  • Energy Efficiency: Look for models with a high Coefficient of Performance (COP). The higher the COP, the more efficient the heat pump.
  • Features and Brand Reputation: Consider heat pumps with additional features like digital controls, quiet operation, and compatibility with smart home systems. Research brands for reliability and customer service - we have a comparison of AquaCal vs Hayward heat pump and AquaCal vs Pentair heat pump if you’re looking for insight.

Speaking of AquaCal, this manufacturer has been known as the #1 choice for pool heating solutions since 1981. OutdoorDirect is proud to offer the entire lineup of AquaCal pool heat pumps, whether you need a small pool heat pump or a commercial pool heat pump.

With industry-leading 7 year warranties, world-class customer service, and smart features that give you unprecedented control, we encourage you to consider either the AquaCal HeatWave SuperQuiet Heat Pump or the AquaCal TropiCal Heat Pump series.

Pre-Installation Preparation

With your pool heat pump selected it’s time to take a few preparatory steps that will ensure a smooth installation process:

  • Site Inspection: Check the installation site for proper drainage, stability, and access for maintenance. The ground should be level and strong enough to support the heat pump’s weight.
  • Tools and Equipment: Gather the necessary tools, including screwdrivers, wrenches, electrical supplies, plumbing materials, and safety gear.
  • Permits and Regulations: Verify local building codes and obtain necessary permits. Ensure the installation complies with electrical and plumbing standards.

Where is the Best Place to Install a Heat Pump in a Pool?

This is one of the most important considerations, as it will influence the longevity and efficiency of your heating solution. 

Ideally, the heat pump should be close to the pool to minimize heat loss in the piping. However, it should not be so close as to be affected by splashed water or chemicals. There’s a fine line between too close and too far.

Airflow plays a part here as well. The heat pump needs sufficient space around it to ensure adequate air intake and exhaust. Poor airflow can reduce efficiency and lead to overheating.

Think about the amount of sunlight exposure the pump will get as well, especially if you aren’t housing it within a separate cabinet or shed. While direct sunlight can improve efficiency slightly, too much exposure can cause the unit to overheat. 

Finally, think about your level of access to the pump. Yes, you want it out of sight and out of mind - but you need to be able to get to it for maintenance and repairs. Walk around your yard and think about where exactly offers the best balance of all these factors. 

How Far Does a Pool Heat Pump Need to Be From the House?

In choosing the best place to install a heat pump in a pool you should also consider proximity to your house. The reason is that heat pumps can generate noise, which could be disruptive if too close to living spaces. 

Check the manufacturer’s guidelines for noise levels to determine an appropriate distance. This won’t be as much of a concern if you invest in the silent operation of a HeatWave SuperQuiet unit.

Local building codes may specify minimum distance requirements from the house, property lines, or other structures. Typically, a heat pump should be at least 5 feet away from the house to ensure safety and compliance.

Navigating the Installation Process

Now, it’s time to actually learn how to install a pool heat pump. As we said from the start, professional pool heat pump installation is well worth the investment, if not for the improved efficiency and longevity, for the peace of mind. That being said, here’s an overview of the process:

  • Foundation Preparation: Create a stable, level foundation for the heat pump, typically a concrete pad or compacted gravel base. The foundation should be large enough to accommodate the heat pump and allow for drainage.
  • Positioning the Heat Pump: Carefully place the heat pump on the foundation, maintaining the recommended distance from the house and ensuring there’s ample space around it for air circulation and maintenance.
  • Connecting Plumbing: Connect the heat pump to the pool’s circulation system. This usually involves integrating PVC pipes from the pool’s filter output to the heat pump and then back to the pool. Use valves to control the flow and make future servicing easier. Ensure all connections are tight and sealed to prevent leaks.
  • Electrical Wiring: This step should be performed by a licensed electrician to comply with local codes and ensure safety. The electrician will connect the heat pump to the power supply, ensuring it has a dedicated circuit. Grounding the heat pump is crucial to prevent electrical hazards.
  • Checking the Installation: Before starting the heat pump, check all connections for leaks and ensure the electrical wiring is properly insulated and secured.

Testing and Commissioning

At this point, you’re ready to put your work to the test. Start up your heat pump following manufacturer guidelines, watching out for unusual noises or vibrations. 

Check the flow of water through the heat pump to ensure it’s within the manufacturer’s recommended range. Adjust the valves as necessary to achieve proper flow.

Set the desired temperature on the heat pump’s thermostat and observe the heating process. Ensure the heat pump achieves and maintains the set temperature efficiently.

Let the heat pump run for a continuous cycle to ensure it operates smoothly without interruptions or fluctuations in performance.

Maintenance Tips

While the work of actually installing a pool heat pump is complete, you should conduct ongoing maintenance to ensure your unit runs smoothly for years to come. You can handle this yourself, or again, leverage the expertise of a professional. 

One thing you can definitely take on is routine cleaning, though. Keep the exterior of the heat pump clean of debris, leaves, and dust to ensure the airflow is unobstructed. Clean or replace filters regularly to maintain optimal airflow and water circulation.

You should also regularly inspect plumbing connections and the heat pump itself for any signs of leakage. It’s worth investing in an annual check-up with a professional to inspect the heat pump’s components, refrigerant levels, and overall operation.

If necessary, follow the manufacturer’s instructions for winterizing the heat pump to prevent damage during cold weather. And that’s it - you can now enjoy a warmer pool and an extended swimming season!
