Do Pool Heating Pumps Use Too Much Electricity? Myths vs. Facts

Admin / May 10, 2025

One of the most common concerns we hear from pool owners is how much energy their swimming pool heating system will use. Overwhelmingly assumed that a swimming pool heating pump consumes an excessive amount of the capacity and, thus, is an unwarranted luxury. But just how much of that belief is true? In this blog, we will clarify myths and help you understand how pool heating pumps consume power. From efficiency ratings to energy-saving tips, let's find out what's true and what's not.

The Myth: “Pool Heating Pumps Will Skyrocket Your Electricity Bill”

Myths abound, and perhaps the most common myth is that swimming pool heaters — particularly electric heat pumps — are going to add a ton to your electric bill. This myth has resulted in many people refusing to install a heater entirely, or using it only lightly, even in the colder months when it is most needed. In reality, though, the situation is a bit more nuanced. Although pool heaters undoubtedly use electricity, the newer technologies powering them are more efficient than some might think.

The Facts: Understanding How Pool Heating Pumps Work?

To make sense of energy consumption, we need to first understand how a swimming pool heating pump works. Instead of creating heat directly, like a traditional electric heater, a heat pump extracts warmth from the air and then transmits it to the pool water using a compressor and a heat exchanger. That makes it orders of magnitude more energy efficient.

Heat pumps are evaluated in terms of efficiency by their Coefficient of Performance (COP). A COP of 5, for instance, indicates the pump generates five units of heat per unit of electricity used. Current heat pumps have a Coefficient of Performance (COP) between 4 to 7, which depicts a great energy performance. This performance makes their use one of the most affordable heating options around today.

Comparing Pool Heating Pumps to Other Heating Options

It is also useful to compare the options when evaluating heating systems. Here's how a swimming pool heating pump compares.

• Gas Heaters: Fast to warm up, expensive to use and not as energy-efficient.
• Electric Resistance Heaters: Heat using electricity, but use more power overall.
• Solar Heaters: Eco-friendly and cost-efficient long-term, but need continuous sunlight.

Gas heaters tend to be faster, and solar options are more environmentally friendly, while electric heat pumps provide a good middle ground of reliability and energy efficiency, even in variable weather conditions.

What Affects Energy Consumption?

The amount of electricity your heating pump uses depends on several factors. These include:

• Pool Size: Bigger pools will take more energy to heat.
• Temperature Settings: The higher the temperature you set the pump at, the more energy it will use.
• Climate: Colder climates generally need more heating effort.
• Usage Time: A longer runtime means a higher power consumption.
• Pump Age and Maintenance: Older pumps or those poorly maintained are less efficient.
• Insulation and Covers: Pools that are not covered use more heat and require more heating.

Having a better grasp of these variables helps you to control your energy usage and expenses.

Myth-Busting: Common Misconceptions Debunked

Let's take a closer look at some of the most common myths:

• Myth #1: Heat Pumps Run Non-Stop

  Fact: Heat pumps run only until the set temperature is achieved. After that, they come on and off to keep warm, as efficiently as memory space.

• Myth #2: They Don't Work in Cold Weather

  Fact: While efficiencies drop in colder climates, newer models are designed to work in frigid temperatures.

• Myth #3: All Pumps Use the Same Amount of Power

  Fact: Energy-efficient models, particularly those with Energy Star ratings, consume less electricity than basic units.

• Myth #4: Nothing Can Control the Power Usage

  Fact: You can control energy usage by adjusting settings, using timers, and implementing smart pool accessories for swimming pool efficiency.

Tips to Maximise Efficiency and Lower Costs

If you're installing or already have a heat pump, here are a few ways to use energy wisely:

• Use a Solar Cover: Keep heat in overnight or when the pool is not being used
• Schedule Operation During Off-Peak Hours: Some utility companies even offer lower rates at night or during specific times.
• Regular Maintenance: Change filters and inspect refrigerant levels yearly.
• Set a Moderate Temperature: Pool temperatures of 78-82°F are typically comfortable and energy-sustainable.
• Use Smart Controls: Automate heating according to your usage pattern and weather conditions.

These simple tips can help you achieve warmth in your pool without the hefty electricity bill.

Is a Pool Heating Pump Worth It?

When it comes to heating a swimming pool wisely, a swimming pool heating pump is the ideal compromise between comfort and efficiency. It's not entirely free of operating costs, but it's far from the energy monster it's often portrayed as. It will outlive your old system, and the long-term savings plus the increased comfort make it worthwhile for all but a few pool owners.
