As the weather gets colder, swimming pools start to close up for the winter. But what if you do not have to cover your pool during cold weather? Pools can now stay open all year long, thanks to an ideal pool heater for winter.
Here are five different ways to keep your pool warm over the cold months.
1. Gas heaters
Gas heaters are powered by propane or natural gas to heat the water in your pool. Regardless of the air temperature, their reliance on a dedicated gas line makes them consistently reliable.
Another advantage is that they heat the water quickly, so your pool is ready in just a few minutes. While gas heaters are more effective than heat pumps in harsh climates, they come at a cost. Expenses can run up to $500 per month! They are also less energy-efficient and may need to be replaced every five years.
2. Electric resistance heaters
Pool heaters that run solely on electricity mean higher cost. They are also more expensive to install than gas heaters. The main advantage of electric heaters is reduced heat loss. Gas heaters tend to lose about 1° per hour compared to 1° every three hours for electric heaters.
3. Solar pool heaters
Solar pool heaters are the most efficient and economical among all pool heating options regardless of climate. How do they work? Solar heaters pump pool water through a filter. Then they heat the water through solar collectors. Finally, the heated water is sent back to the pool. Solar heaters are great for keeping pools warm at night and during cloudy days.
4. Air-source heat pump
Heat pumps are popular because they are inexpensive and energy-efficient. They work by transferring heat from the air to the swimming pool. Unfortunately, most air-source heat pumps do not work in ambient temperatures below 50 degrees Fahrenheit.
5. Water-source heat pump
Water-source heat pumps may be the best option for swimming pools in harsher climates. Utilizing new technology, these pumps transfer heat from a water source such as ponds, lakes, and even wells. While they work well in temperatures that dip below 50°F, these heat pumps require a complex installation and long water lines. However, if you are willing to pay for the higher upfront cost, water-source heat pumps are more cost-effective.
What are solar blankets?
Whichever pool heater for winter you choose, solar blankets can help reduce your water heating costs. However, heat loss is around 75% due to evaporation, so you should cover your pool with a solar blanket. We recommend that you roll out the solar blanket at night and during cloudy days to prevent evaporation.
If you plan to keep your pool open during winter, be sure to monitor the outdoor temperature. You do not want to risk ruptured pipes or any other damage to your pool from freezing weather. One way to keep your pool from freezing is to install an automatic timer. This device is wired to the breaker and only activates the heating system at a pre-set temperature.
More tips on how to keep your pool heated during winter
- Make sure your pool heater for winter is designed to work in your climate. Many heat pumps do not function below 50°F, but some heaters work well under 30°F. Here at Cherry Pool Services, we can help you find the most suitable heater for your winter months.
- A pool heater for winter is more than just keeping the water warm enough for swimming. Extreme weather can lead to frozen pipes, which is why you must leave the heater on at all times. You might also want to invest in a backup power source in case of a power outage during winter storms.
- The ambient heat from the pool should keep the immediate perimeter warm as well. However, the pathway leading to the house can easily accumulate ice or snow. Ensure the pool deck can withstand the temperature shift from the warm pool water to the cold air.
