Most Common Swimming Pool Heater Problems and How to Solve Them
Swimming is among the most popular recreational activities in New Zealand. In fact, Swimming.org.nz reveals that around 30.2 percent of Kiwis choose swimming over other hobbies. Interestingly, while there are plenty of beaches that residents can enjoy, thousands choose to invest in their own pools. Families, especially those with kids, see swimming pools as a worth-it property add-on. Instead of heading to public pools or resorts, families can simply enjoy swimming while at home.
A pool indeed comes handy all year round, especially if it’s equipped with a heating pump. With a properly installed pool heater, everyone can take a plunge in the water and enjoy a pleasant swim anytime. But what happens if the heating pump fails to do its job? What might have caused the issue? Can you restore it to its former glory? Learn more about the common swimming pool heat pump problems and how you can solve them in the guide below.
Help! My swimming pool won’t heat
There are plenty of potential reasons why your pool won’t heat. One example is a dirty pool filter. With a filthy filter, your pool’s water flow decreases, keeping the water’s temperature cool. If you notice that the water stays cool even with the heater switched on, try checking the filter and the pressure gauge. If the pump runs, but the pressure metre reads zero or any value close to zero, you know there’s something wrong.
If the filter isn’t the cause of the problem, it might be the heater’s size. If you use the wrong size, it would be harder for the system to heat your pool. Make sure to refer to the manufacturer’s manual and consult with an installer to know if you should switch to a larger size.
My pool heater won’t stay on
Plenty of pool owners also complain about heaters that won’t ignite. There are various potential causes of this issue. The first one is a faulty heater switch. Check if it’s switched on. You must also check the thermostat setting. Find out if it accurately reflects the pool’s temperature. After reviewing the two, inspect the pilot and gas supply valve. The pilot should be lit, and the valve should be pointing to the on position.
If you’re using an electric unit, check the terminals and determine if there is corrosion or weak electrical connections. You can also inspect the fuse, high limit switch, and pressure switch. The meter should show you the voltage. If not, then you may need to have them replaced.
My pool heat pump is making a weird noise
Pool heaters can sometimes make weird sounds like grinding, bangs, and whines. If your heater is producing unusual noise, you should check the system for debris and other materials. Then, back-flush the system to remove dislodged particles completely. If that’s not causing the issue, then you can try to look for the pressure switch. A damaged pressure switch tends to keep the pump running even after you shut it off.
The heater is leaking after lighting the burner
Oftentimes, people who use gas pool heaters complain that their heater is leaking when they light the burner. This issue often results from a faulty internal bypass or, sometimes, excessive flow of water. To address this concern, you may need to install an additional external heater to decrease water flow.
If the heater leaks water even if you don’t switch on the burner, you may need to examine the gasket and connections. Alternatively, you might need to call for a heat exchanger replacement.
The solar collectors are leaking
Pool heaters can be powered by gas, electricity, or solar energy. While electric and gas heaters are the most preferred types, solar heating pumps are also gaining more traction because of the increased use of solar power in New Zealand. If you’re also using one, then you might encounter problems such as solar collector leakage.
The best way to address such a problem is by isolating the leaky tubes. If that’s not enough to deal with the leaks, you can call someone to repair it for you.
When to call an expert
Having a pool heater comes with a lot of benefits. However, when it breaks down or stops working normally, it can be incredibly frustrating. Often, it’s okay to solve the problem on your own. But, some issues are best left to the professionals. For example, if the case calls for a replacement of electrical parts or gas valves, don’t attempt to try a DIY repair. It might result in an accident.
If you’re not sure why your pool heater is acting up, call a professional swimming pool heater installer. It’s a faster, safer, and more practical option, especially if you lack technical and mechanical background. Once the installer or repairman determines what to do, you can request a quote to decide where you should go from there.
