Should an ingound pool filter be run at the same time as a heater or can you just alone?

An inground pool filter and heater can be run at the same time, but it is not necessary to do so. The filter's job is to remove dirt and debris from the pool water, while the heater's job is to warm the water. If you are not planning to use the pool, it is not necessary to run the heater, and you can save energy by turning it off. However, if you plan to use the pool, it is best to run the filter and heater at the same time so that the water is clean and warm.

Here are some additional tips for saving energy when using your pool heater:

* Set the heater to the lowest temperature that is comfortable for swimming.

* Use a pool cover when the pool is not in use.

* Turn off the heater when the pool is not in use.

* Consider using a solar pool heater, which can help you save money on energy costs.
