The pool heater is an essential part of your pool system. When it starts making a weird noise, it is best to contact a pool service professional for expert repairs. Because the heaters are more complicated than pumps, they usually need a professional pool service company. It is best to schedule an appointment with a professional at the first sign of a problem with your pool heater. This will help ensure that the pool stays comfortable for the fun of your friends and loved ones. These professionals will help restore the heater to the best working condition.
Reasons the pool heater is making a strange noise include:
1. Buildup of calcium
A buildup of calcium occurs when the pool water pH level is off, causing the formation of hard water. This will bring problems if you do not deal with it immediately. Hard water will leave unappealing deposits on the pool tiles, similar to what takes place in the toilet, bathroom sink, and bathtub, resulting in cloudy pool water.
If there’s too much calcium scale buildup that you can see at the waterline, it probably has developed inside the pool heater and pool pump too. These deposits clog the heater and block the flow of water, which leads to a grinding noise.
To get rid of the buildup, it is best to use either a tile cleaner or vinegar for scrubbing the pool tiles. After that, drain the pool several inches to soften the water, then use a garden hose to refill it.
Lastly, get in touch with a professional at Pool Surgeon so that they can get rid of deposits from the pool heater. If the weird noises are still emerging from the pool heater, it is best to call in the professionals. They will locate the issue and find a solution to prevent it from interfering with your peace.
2. Problem with gas pressure
A common issue of most pool heaters is inadequate gas supply, so use a manometer to look at the gas pressure. You can take the pressure reading of the gas by connecting the manometer to the pipe plug.
The recommended level is 10.5 - 11.0 inches water column for propane and natural gas is 3.7 – 4.0 inches WC. If there’s a low gas pressure reading, it might mean the pool heater is not emitting well, or there’s not enough air getting to your pool heater, which results in whistling sounds.
If the pressure is too low, you can adjust the gas valve. Luckily, doing this is easy. There’s an adjustment screw on the valve. Just turn it clockwise with your heating system running and the manometer still connected until you attain the right pressure.
3. Defective pressure switch
This switch makes sure that the right quantity of incoming water is available before it turns the pool heater on. If this switch is defective, it may be limiting water flow into the pump, which creates grating or whistling sounds.
Replacing the faulty pressure switch is the best option. This is easy work, provided that you use the guide from the manufacturer. You will see the type of switch to purchase for the heater and how you can install it.
If you doubt DIY skills when it comes to handling the repair work, you can always contact a pool service professional to fix it.
Other common problems with a pool heater include:
Wrong heating
When there’s a repair issue with the pool heater, you might also find that it will heat the pool insufficiently. A clogged or dirty pool filter can cause improper heating. On the other hand, insufficient heating might also be due to an incorrect pool heater size. A very small filter won’t produce adequate heated water to help keep the pool at a comfortable temperature.
The heater doesn’t switch on
If this happens, it may be due to a clogged or dirty filter. When you have a clogged or dirty filter, this can cause the pool heater to switch off. Corroded terminals can also damage an electric heater. At the first indication that the heater doesn’t switch on, it’s best to get in touch with a professional to schedule an appointment.
