Best time of day to run a pool pump: Night or Day?

July 24, 2019

The time of day that you run your pump matters. To your pool and your wallet.

Here’s what we mean by that:

Most people run their pumps during the day while they’re swimming. And that makes sense. There’s nothing wrong with that. What’s important is getting those 2 full cycles in.

Of course, there are a few factors to consider when running your pool during the day.

Without a cover on the pool, heat and water loss is at it’s highest during daylight. So if you’re running your pump and not using a cover, start now. It’ll save you money, reduce water loss, and improve heat retention.

But the question remains:

What’s the best time of day to run a pool pump?

If you want the best water circulation at the lowest cost, run the pump at night.

Running your pump at night is the best time for a few reasons:

First, while it’s important to circulate your water at least a little during the daytime, running it at night is far more efficient.

Electrical companies charge less for energy use during non-peak hours, typically between 9 pm and before 8 am.

So to save and keep your pool looking clear, run the pump at night.

Of course, there’s a good chance that you might be human now and then and forget to turn on the pump before bed. Luckily, there’s a tool for that.
