Why should one restrict pool time to summer only? Let the children and elderly take a dip, that too in the winter, with the help of a water heater. Moreover, if you have an inground pool adding a heater to it can turn it into a multipurpose leisure structure. A heating device can change the regular pool to a sauna or lukewarm spa. However, with all the perks, one disadvantage is the sensitivity of a pool heater is repeated repair. Let’s see what you can do to temporarily repair your pool heater until help arrives.
Common Causes Why A Pool Heater Might Need Repair
Listing down some usual problems why repair might be needed for the heater in the pool.
Pool Heater Does not start
In some cases, the heater fails to start; some reasons that contribute to the problem:
- The heater is not on, and the temperature is not set accordingly.
- The filter has a clog or is broken.
- Pilot light is not lit.
- The gas supply valve to the pool heater is off, seemingly looking like it needs repair.
- The filter valve is closed.
Consistent water flow is imperative to needed for a surety that the pool heater is functioning adequately. Pool heaters have pressure sensors that work with an internal bypass. Most of the time, they do not turn on until they receive the right amount of pressure and push.
The Pool Heater Turns On and Off
This phenomenon is called cycling. It means your pool heater can turn on and off and needs repair. It could serve as an indicator of a severe malfunction, usually electrical. However, it is not always the case. The power supply is usually the culprit.
Another reason for this to happen is poor pool water chemistry which makes the heater experience irregular cycles.
Bad water chemistry can lead to corrosion and damage to the internal parts of the pool. This includes a heater as well as your pool pump.
This is the main reason why attention to water chemistry is a must. Since corrosion is one of the causes of your pool heater cycles, check for components that have either rust, scaling, or oxidation.
The components that need checking, include pressure sensors, thermal regulators, and high limit switches. The parts are cleanable and replaceable if need be.
Inadequate or Non-Heating Pool Heater
Under some circumstances, the pool heater starts but fails to heat up the water. Usually, the reason behind it is a dysfunctional temperature sensor or maybe an inadequate thermostat setting.
Some features to see in such a situation:
- Adequate water levels.
- Power delivery.
- Proper temperature level.
If the pool heater makes unusual noises, it usually alarms a fault. This may include faulty pressure switches, blockages, or loose parts. Most of the time, you can find the source of the noise with the help of a manual. Check for any pool heater parts that may get loose and need tightening or repair.
