What maintenance does a pool heater need?
A pool heater is a great way to extend the swimming season and enjoy your pool year-round. However, like any other piece of equipment, pool heaters require regular maintenance to keep them running efficiently and safely. Most models require at least two maintenance checks per year: once in the spring before the start of the pool season and once in the fall when the pool is closed.
Spring maintenance
- Check the water level in the pool. The water level should be at least halfway up the skimmer.
- Inspect the pool heater for any leaks. Look for water dripping from the unit or any wet spots on the ground around the heater.
- Clean the pool heater's filter. A dirty filter can restrict water flow and cause the heater to overheat.
- Check the pool heater's electrodes. The electrodes are responsible for igniting the gas burner. If the electrodes are dirty or damaged, the heater will not be able to start.
- Test the pool heater's safety features. The safety features include the high-limit switch and the low-water cut-off switch. These switches are designed to shut off the heater if the water temperature gets too high or if the water level drops too low.
Fall maintenance
- Drain the pool heater. Draining the heater will prevent water from freezing inside the unit and damaging the components.
- Disconnect the pool heater from the gas supply.
- Cover the pool heater with a tarp or other protective covering. This will help to protect the unit from the elements.
Additional maintenance tips
- Keep the pool heater's area clean and free of debris.
- Inspect the pool heater's sacrificial anode rod. The sacrificial anode rod is designed to corrode instead of the heater's metal components. If the sacrificial anode rod is worn out, it should be replaced.
- Have the pool heater serviced by a qualified technician every few years. A qualified technician can inspect the heater, clean the components, and make any necessary repairs.
