7 Ways to Keep Heat in the Pool

Posted by

Have you ever stepped into a pool only to be greeted by an unexpected chill, even on a warm day? Keeping your pool at a comfortable temperature is key to enjoying your swim, no matter the season. One of the most effective tools is a pool heat pump, such as the Hayward Heatpro Heat Pump, an ingenious device designed to maintain that perfect balance of warmth in your aquatic retreat.

In the following guide, we'll unveil seven savvy strategies to keep the heat in your pool, ensuring every dip is as inviting as the last. Whether you're a relaxed swimmer or an avid pool enthusiast, these ways will help you enhance your pool's heat retention, prolonging those delightful poolside days.

Understanding Pool Heat

Understanding Pool Heat

A pool can lose its warmth in a few ways. Think of it like a warm drink that cools down after a while. The main reason is evaporation - this is when water turns into vapor and rises into the air. The wind can make this happen faster, just like how a breeze can make you feel colder when you're wet.

Keeping your pool warm is like using a blanket to stay cozy. A pool heat pump works like this blanket but in a clever way. It takes warmth from the air and gives it to your pool water, making it just right for a swim. And no matter what type of pool you have, there's a heat pump pool heater that fits. With our experience, we know how to choose the perfect one to keep your pool warm.

What is the Normal Temperature of a Swimming Pool?

What is the Normal Temperature of a Swimming Pool?

Maintaining the right temperature is more than just about comfort; it extends your swimming season, too. With a swimming pool heat pump, you can enjoy warm water even when the air is cool, meaning more pool time throughout the year.

  • Ideal Temperature Range: The best water temperature for most pools is between 78 to 82 degrees Fahrenheit. This range is comfy for everyone—warm enough to step in without a shiver and cool enough to refresh you.
  • Health and Comfort: Warmer water, around 82 to 86 degrees, is often better for children and those swimming for fitness, as it helps relax muscles and makes the water more comfortable.

7 Ways to Keep Heat in the Pool

7 Ways to Keep Heat in the Pool

To make the most of your pool, retaining the heat is crucial. Here are 7 ways to keep the heat in your pool inviting by preserving its warmth efficiently.

1. Air-Source Heat Pump

The air-source heat pump is the eco-friendly warrior of pool heating. This device works by extracting warmth from the surrounding air and transferring it to your pool, functioning even on cooler days.

Unlike traditional heaters, an air-source heat pump pool is remarkably efficient, reducing running costs over time. With this technology, you can keep your pool at a pleasant temperature, assuring you a warm welcome whenever you decide to dip.

2. Use a Solar Cover

Solar covers act as a layer of protection for your pool, not unlike a cozy blanket on a cool night. They consist of large sheets of plastic with air bubbles designed to trap and retain heat from the sun and then transfer it to the pool water.

Placing a solar cover over your pool effectively prevents heat from escaping. When combined with a swimming pool heat pump, the cover can significantly enhance the system's efficiency by maintaining the warmth that the pump imparts, reducing energy use and cost savings.

3. Combine a Solar Cover and Pool Heat Pump

Uniting a solar cover with a pool heat pump is like having a tag team to keep your pool's temperature steady. The solar cover acts on two fronts: it collects heat from the sun and also prevents that heat from escaping.

On the other hand, the heat pump pool heater maintains a constant temperature efficiently. Together, they form an excellent strategy for conserving energy and ensuring that the warmth stays locked in, extending your swim season without sending your utility bills through the roof.

4. Gas Heaters

When rapid heating is required, gas heaters come to the rescue. They generate warmth by burning natural gas or propane, which is then transferred directly to the pool water, providing a swift temperature rise that's perfect for unexpected cold snaps.

While gas heaters can quickly bring the water to a desired temperature, they may not be as cost-effective in the long run compared to a heat pump pool heater, which is more energy-efficient for consistent, daily heating.

5. Windproof Pool Enclosure

Consider a windproof pool enclosure, your pool's shield against the chilly touch of the wind. These structures surround your pool, blocking gusts that can lead to significant heat loss.

The logic is simple: less wind over the water surface equals less evaporation and retained warmth.

When paired with a heat pump pool heater, enclosures ensure that the heat is kept where it belongs - in your pool, providing a cozy, uninterrupted swimming experience even on breezy days.

6. Liquid Solar Pool Cover

Imagine an invisible blanket on the surface of your pool; that's what a liquid solar pool cover creates. When you pour this special liquid into the pool, it spreads out and forms a thin layer that's hard to see but easy to feel.

It helps to hold in the heat by cutting down on water evaporation. This type of cover is safe for swimmers, eco-friendly, and doesn't bring any unwanted chemicals into your pool. However, in windy areas, the effectiveness might be reduced, as strong winds can disturb the liquid layer, breaking the heat-holding barrier it forms.

7. Solar Rings

Solar rings are a stylish and practical twist on traditional pool covers. These are floating discs that you scatter across the pool surface. They work similarly to a solar cover by absorbing sunlight and converting it to heat, but they cover smaller areas, making them easier to handle and adjust.

For optimal effectiveness, place them side by side to cover as much of the pool as possible. They collaborate with swimming pool heat pumps, adding an extra heat retention layer.

Factors to Consider When Choosing a Pool Heat Pump

Factors to Consider When Choosing a Pool Heat Pump

When selecting a pool heat pump, here are the key factors to consider:

  • Pool Size: Choose a heat pump that can handle the volume of your pool, ensuring efficient and effective heating.
  • Local Climate: Opt for a model suitable for your local extreme weather conditions, which can function well even during cooler temperatures.
  • Energy Efficiency: Look for heat pumps with high energy efficiency ratings to reduce operating costs and environmental impact.
  • Durability: Invest in a heat pump known for its durability and reliability to withstand the test of time.
  • Maintenance Requirements: Consider the maintenance needs and ease of service for the long-term upkeep of the heat pump.
  • Manufacturer Warranty: Check the warranty offered, as a good warranty can indicate a heat pump's quality and longevity.


Keeping your swimming pool warm and welcoming is an art balanced by science. Employing a pool heat pump offers a reliable and energy-efficient solution to extend your swimming season. By understanding and utilizing the various methods and technologies available, such as heat pump pool heaters and effective heat retention strategies, you can ensure that your pool remains a haven of comfort.

Whether you're looking to install a new swimming pool heat pump or exploring ways to keep the heat in your pool, the key is to choose the right approach that fits your specific needs. With the right setup, your pool can be a warm, inviting oasis for family and friends to enjoy anytime.
