Best Above Ground Pool Heaters Gas Reviews & Buyer's Guide in 2024

What is the best option for heating above ground pools?

The best option for heating above ground pools depends on various factors such as budget, climate, and personal preferences. Here are a few common options:

1. Solar Covers/Blankets: Solar covers are cost-effective and environmentally friendly. They capture and retain heat from sunlight, helping to warm the pool water. However, they rely on sunlight availability and may not be as effective in colder climates or during cloudy days.

2. Heat Pumps: Heat pumps use electricity to transfer heat from the air to the pool water. They are energy-efficient and can work in various climates. Heat pumps are a popular choice for above ground pools due to their relatively low operating costs.

3. Electric or Gas Pool Heaters: Electric or gas heaters provide quick and reliable heating for above ground pools. Electric heaters use electricity to generate heat, while gas heaters use propane or natural gas. They can heat the pool water to desired temperatures regardless of weather conditions. However, they tend to have higher operating costs compared to other options.

4. Wood-Burning Pool Heaters: Wood-burning heaters are an alternative for those looking for a more traditional and cost-effective heating method. They require a supply of firewood and may require more manual labor to operate and maintain.

Consider your specific needs, budget, and local climate when choosing the best heating option for your above ground pool.

Is it better to heat a pool at night?

It is generally more efficient to heat a pool during the day when the air temperature is warmer and the pool is exposed to direct sunlight. Sunlight can help raise the pool's temperature naturally, reducing the amount of energy needed for heating.

Heating a pool at night can be less efficient because the air temperature tends to be cooler, and there is no sunlight to assist in warming the water. However, if you have a heating system with a timer or programmable thermostat, you can set it to start heating a few hours before you plan to use the pool. This way, the pool can reach a comfortable temperature by the time you want to swim.

To optimize energy efficiency and reduce heating costs, it is recommended to use a pool cover or solar blanket. This helps to retain the heat gained during the day and minimize heat loss during the night, regardless of whether you heat the pool at night or during the day.

Ultimately, the best heating strategy for your pool will depend on factors such as your specific climate, the heating system you use, and your preferred swimming schedule.

How long does it take to heat the pool with a gas heater?

The time it takes to heat a pool with a gas heater can vary depending on several factors, including the size of the pool, the desired temperature increase, the heater's capacity, and the ambient conditions. Here are some general guidelines:

1. Pool Size: Larger pools will typically take longer to heat compared to smaller pools.

2. Desired Temperature Increase: The greater the temperature difference between the current pool water temperature and the desired temperature, the longer it will take to heat the pool.

3. Heater Capacity: Gas heaters come with different heating capacities, usually measured in BTUs (British Thermal Units). Higher BTU ratings generally mean faster heating times.

4. Ambient Conditions: The outside air temperature and weather conditions can influence the heating time. Colder ambient temperatures will require more energy and time to heat the pool.

As a rough estimate, a gas pool heater can raise the water temperature by approximately 1-2 degrees Fahrenheit per hour. Therefore, if you have a 10,000-gallon pool and want to increase the temperature by 10 degrees, it may take around 5-10 hours. However, please note that this is just a general estimate, and the actual heating time can vary based on the factors mentioned above.

It's worth considering energy efficiency measures such as using a pool cover to retain heat and minimizing heat loss when the heater is not in use.

What pool heater heats the pool the fastest?

Among the commonly available pool heating options, electric resistance heaters typically provide the fastest heating times. Electric heaters directly convert electrical energy into heat, allowing for rapid heating of the pool water. However, it's important to note that electric resistance heaters tend to have higher operating costs compared to other heating options due to the energy required to generate heat.

It's worth mentioning that heat pump heaters, although they may take longer to heat the pool initially, are more energy-efficient once they reach the desired temperature. Heat pumps transfer heat from the surrounding air or ground into the pool water, so their heating speed may be slower than electric resistance heaters. However, they can maintain the desired temperature efficiently and are generally more cost-effective to operate in the long run.

Ultimately, the heating speed will also depend on factors such as the size of the pool, the temperature difference, the heater's capacity, and the ambient conditions. It's recommended to consider a heater that strikes a balance between heating speed, energy efficiency, and operating costs based on your specific needs and preferences.
