Want to keep your pool heater running efficiently, avoid surprise breakdowns and extend the life of your system? A bit of regular maintenance goes a long way.
So, here’s your go-to guide to keeping your pool heat pump in top condition.
Your pool heater works hard behind the scenes to keep every swim comfortable. But without regular maintenance, it could become less efficient, more costly to run and prone to breakdowns just when you need it most. Plus, a well-maintained system is also safer, more consistent and better for your overall pool health. It will use less energy, last longer and give you fewer headaches in the long run.
To run efficiently, your heat pump needs plenty of airflow. Keep the area around it free from leaves, grass clippings, and other debris – and check that vents or grills aren’t obstructed. It’s also important to keep the coil itself clean, as dirt and buildup can reduce heat exchange efficiency. A quick rinse with a hose (while the unit is off) can help maintain optimal performance. It’s a simple job, but one that makes a noticeable difference to both efficiency and longevity.
Good water circulation is essential for heating. If water isn’t flowing properly through your system, your heat pump will have to work harder (or may shut off entirely). Check your filter pressure gauge, ensure the pump basket is clean and make sure valves are in the correct position. If anything seems off, it’s best to investigate before problems snowball.
Clogged filters restrict water flow and can put unnecessary pressure on your entire pool system - including the heater. Make a habit of checking and cleaning your filters regularly.
A quick visual inspection of your heater can reveal any signs of water pooling around the base or unexpected drips from the plumbing. If you spot a leak, make sure you don’t ignore it - even small issues can become costly if left too long.
If your water temperature feels off, it could be the thermostat. Monitor it over a few days to ensure it's reading accurately and holding temperature as expected. If not, a service technician can recalibrate or replace it.
Water that’s out of balance can cause scale or corrosion, which puts your heater under strain and shortens its lifespan. We recommend taking a sample to a dedicated pool shop (not a general hardware store) for an accurate water test.
If you’re not using your pool over winter, it's still a good idea to run your heat pump for a short time every few weeks. This helps keep parts lubricated, prevents stagnation and gives you the chance to catch any issues before spring arrives.
Some things are best left to the experts. An annual service gives your heat pump a thorough once-over: cleaning internal components, checking electrical connections, inspecting for leaks or corrosion, and making sure everything’s running safely and efficiently.
A professional can also spot issues you might miss - like thermostat faults, electrical problems and more. If you’ve noticed ongoing issues (like inconsistent temperatures, rising power bills or odd noises), now’s the time to get it checked out properly.
