Should I Cover My Pool Filter And Heater For Winter?

A pool filter should be winterized to prevent cracking. A pool heater should also be winterized to avoid overheating and bursting due to the expansion of the freezing water inside. A cover will not protect the filter from freezing, but it will prevent it from oxidization. Winterizing a filter will remove its outer surface. Ideally, the filter should be placed inside its piping to avoid freezing. Also, make sure it is not too heavy or removable.


Instead, the manufacturers of pool heaters typically only advise their customers to cover them after they have been installed. This is because they only sell covers that are made for a specific outdoor product. The biggest issue with covering a pool heater is the buildup of moisture. This issue can lead to corrosion on the inside of the unit.


Another issue is that the cover may still be on even though the pool heater is turned on. This can happen even if the person who's responsible for keeping the pool hot has no experience with this type of operation. Without the proper air flow over the coils of a heat pump, or over the exhaust gases from a gas heater, it will not operate properly. This issue can cause expensive repairs.


These heaters are designed to endure the harsh weather conditions. To maintain their appearance, they should be regularly wiped down and kept weeds and bushes away from them.


Winterizing and maintaining your pool heater is the only way to ensure that it will not get cluttered and get damaged by rodents, bugs, and other living things. Having a professional pool heater service is also important to prevent getting stung by a spider or a mouse.
