The size of the heater required to heat a swimming pool from 70 degrees depends on a variety of factors including the size and depth of the pool, the average outdoor temperature throughout the swimming season, and the desired water temperature.
Generally, a pool heater should be able to produce at least 50 British Thermal Units (BTUs) of heat per square foot of surface area, so a 40 foot by 20 foot pool would need a heater with a minimum of 40 × 20 × 50 = 40,000 BTUs for a desired set point of 78-80 degrees F. Higher temperatures may require additional heating power depending on environmental conditions and usage cycles.
In order to select the best pool heater for your needs, it is important to consult with a professional to determine the best heater size for your application.

What size pool heater do I need for a 25000 gallon pool?
The size of pool heater you need for a 25000 gallon pool depends on several factors such as the temperature you want the pool water to reach, what type of fuel source you’re using, and the climate and environment of your pool.
Generally, gas heaters can heat anywhere from 125 to 200 gallons of water per minute, while electric pool heaters have a higher recovery rate of up to 300 gallons per minute. To determine the size of pool heater you need, take your pool’s gallon capacity and divide it by the heater’s recovery rate, then divide it again by 60 minutes.
This will give you the time it will take to heat up your entire pool.
For example, if you have a 25000 gallon pool and you’re using a gas heater with a recovery rate of 150 gallons per minute, you would divide 25000 by 150, then divide that number by 60, giving you an approximate result of 100 minutes.
This means it will take about 100 minutes to heat up your entire pool.
Be sure to factor in the climate and environment of your pool when selecting a heater, and make sure it’s a size that will adequately heat up your pool.
How fast will a 400000 BTU pool heater heat a pool?
The amount of time it takes for a 400000 BTU pool heater to heat a pool can depend on a few factors such as the pool’s size and starting temperature as well as the average air temperature of the area.
Generally, it takes an average of 8-12 hours for a 400000 BTU pool heater to heat an average sized pool (roughly 30,000 gallons) from a cold start temperature to the desired temperature. Of course, this assumes that the outdoor air temperature is relatively normal throughout the process (not extremely cold or extremely hot) and the pool is not directly in the sun, as this would affect the amount of time to heat the pool.
If the pool is larger or the outside temperature is hotter or colder, then the amount of time it takes to heat the pool may be different than 8-12 hours.
Is it OK to oversize pool heater?
No, it is not recommended to oversiz e a pool heater. Doing so can cause a variety of issues, such as reduced efficiency due to increased facility costs, excessive cycling of the system, failure of heater components due to increased strain, increased chances of carbon monoxide poisoning, and increased breakdowns and/or repairs.
Oversizing a pool heater can also lead to an unsafe environment due to inadequate preheating of the water and insufficient filtering of the water. Additionally, an oversized pool heater may be too powerful for the pump to circulate, leading to a lack of water circulation and a pool temperature that does not meet expectations.
Lastly, aesthetically the design of the pool may be affected as there may not be enough space to install a larger heater in the equipment area.
Do pool heaters use a lot of electricity?
Yes, pool heaters do use a lot of electricity. According to the U.S. Department of Energy, a single 2.5 horsepower pump used to circulate water in a pool can use anywhere from 1,000 kWh to 2,000 kWh of electricity per month, depending on the size and temperature of the pool.
If a pool heater is added to the system, it could add an additional 500 kWh to 1,000 kWh of electricity usage per month. As such, it is important to be mindful when using a pool heater and to understand the associated costs in order to avoid any surprises when it comes time to receive the electric bill.
Additionally, investing in an energy efficient pool heater can help reduce energy costs while simultaneously providing the desired level of pool temperature.
How many BTUs does it take to heat a 25000 gallon pool?
The exact answer to this question depends on a number of factors, such as the desired temperature of the pool and the outdoor temperature, as well as the size of the pool and the type of heating system used.
As a general rule of thumb, it is estimated that it typically takes 40 BTUs to raise the temperature of one gallon of water by one degree Fahrenheit. Using this estimation, it would take approximately 1,000,000 BTUs to heat a 25,000 gallon pool by one degree Fahrenheit.
Of course, it is important to note that this is only an estimate and the amount of BTUs required could vary depending on the specifics of the situation.
What is a comfortable temperature to heat a pool?
A comfortable temperature to heat a pool depends on a few factors, such as the climate, people’s preferences, and the time of year. Generally speaking, temperatures between 77 and 82 degrees Fahrenheit are considered comfortable swimming temperatures.
In climates that stay hot year-round, pools may be heated as high as 85 degrees Fahrenheit. In cooler climates, temperatures lower than 77 degrees Fahrenheit may be considered comfortable. Ultimately, it’s up to personal preference and people should feel free to adjust the temperature to whatever they are most comfortable with.
How many hours a day should a pool heater run?
The amount of time your pool heater should run each day depends on many factors, including the temperature of the air, the size of your pool, the type of heater you have, and the temperature you would like to maintain.
As a general rule of thumb, most pool heaters should run between 6 and 12 hours a day, depending on your local climate and the size of your pool. In hotter climates, it’s likely you’ll need to run for 8-10 hours a day, and in cooler climates you may need to run for up to 12 hours a day to maintain a comfortable pool temperature.
You may need to adjust the amount of time your pool heater runs each day to keep your pool temperature at the desired level. Finally, consult your pool heater manual or a certified pool service provider to determine the exact amount of time you need to run your pool heater each day to maintain a warm and comfortable pool.
Can a pool heater be too big?
Yes, a pool heater can be too big. When a pool heater is too large, it can consume more energy than needed to effectively heat the water. This results in higher energy costs, as the heater will be running longer and harder to maintain the appropriate temperature.
Additionally, a very large heater can cause quick temperature changes that could be too extreme for bathers to handle. When purchasing a pool heater, it’s important to accurately calculate the size you need by taking into account the size of your pool, the weather in your area, and your desired temperature.
If a heater is too large, it can become difficult to manage, resulting in not only higher energy costs, but an uncomfortable swimming experience.
How do I know how many BTUs my pool heater needs?
In order to determine the BTU output that is needed by your pool heater, you will need to first know some information about your pool. First, you need to know the square footage of your pool – the surface area of the entire water body (not including steps or other extras) should be measured and marked down in feet.
Once you have this number, you will need to know the surface temperature that you expect your pool to attain – for most swimming pools, something between 80-85 degrees Fahrenheit is common. Additionally, you will need to obtain a corrective coefficient that accounts for differences that may be present due to the geographic location of your pool, the materials used in its construction, the depth of the pool, the orientation of the pool to sunlight, and so on.
This may be obtained from a variety of sources, such as your pool’s manufacturer, installation specialist, or local climate data bureau.
Once all of the aforementioned data is collected, the BTU output for your pool heater can be calculated using an online calculator or a specialized equation. The formula is BTU = (Surface area x Temperature rise x 8.25 x Correction factor).
The surface area of the pool is obtained from measurement, the temperature value is typically between 80-85 degrees Fahrenheit, and the correction factor is a decimal value that is rounded or estimated based on the environmental factors discussed previously.
As a result of the formula, once all of the values are entered the output should be a reasonable BTU rating for your pool heater. It is important to note that some pool heater models may have different requirements that may vary based on design and/or manufacturer recommendations, so it is always a good idea to confirm with a professional installer before purchasing a pool heater.
How long should pump run in 15000 gallon pool?
That’s a tricky question, as it depends on the size, type, and brand of the pump that you are using. As a general rule of thumb, pumps should run for around 8 to 12 hours a day for an average 15000 gallon pool.
If your pool is in a heavily shaded area with lots of trees, or if it experiences a lot of storms and heavy winds, then you may want to run your pump for up to 18 hours a day to ensure that your pool is properly filtered and circulated.
Additionally, if you are using an energy efficient pump, it may be possible to reduce the run time to 6-8 hours, saving you money and energy in the process.
Is it better to heat a pool with gas or electric?
The answer to this question will depend on your specific circumstances and preferences. Generally, gas-powered heaters are more powerful and efficient and can heat a pool quickly, but they tend to be more expensive both to install and to operate.
Electric heaters are less expensive, but they require more electricity to operate and can take a longer amount of time to heat a pool. Additionally, electric heaters may require extra safety precautions due to higher power usage.
When deciding between gas or electric, consider the size of your pool, the frequency of usage and the climate of your area. Gas heaters will cost more initially but may be the more cost-effective option in the long-term if you will be using your pool frequently in colder climates.
Conversely, electric heaters may be the more practical choice for smaller pools or for more temperate climates.
In the end, it is best to consult a pool specialist or licensed contractor who can provide you with additional information and advice that is tailored to your exact needs and situation.
Does pool heater size matter?
Yes, the size of your pool heater does matter. The size of a pool heater is determined by two main factors: the surface area of the water that needs to be heated and the temperature change you require.
A larger heater is needed for larger pools, as well as pools that require more of a temperature change. On the other hand, if you have a small pool surface area and don’t need much of a temperature change, then a smaller heater should suffice.
The size of your pool heater will also impact the price and efficiency of the unit. Generally speaking, the larger the pool heater, the more expensive and the more efficient it is. This is because larger pool heaters are able to bring more water to the desired temperature in less time and with less energy.
Additionally, larger pool heaters typically come with more options and features that allow you to customize the temperature to your desired settings.
Finally, you should also consider how often you plan to use your pool before selecting a pool heater size. If you’ll only be using it occasionally, then you may be able to get away with a smaller heater, but if you plan to use it often then you’ll likely want to opt for the larger size to ensure it can keep up with the demand.
In conclusion, the size of your pool heater does matter, as it will determine your unit’s price and efficiency as well as the temperature change you require. Additionally, you should also factor in how often you’ll be using your pool before making a selection.
How much space do you need around a pool heater?
When installing a pool heater, it is important to make sure there is enough space around the heater for proper air flow and ventilation. The exact amount of space needed can vary based on the specific model, but generally an area of at least 3 feet should be kept clear on all sides of the heater.
Additionally, the area should be kept free of combustibles, such as wood and other flammable material. Finally, the area should also have enough room for someone to safely perform any necessary maintenance work.
How many degrees does a pool heater raise temperature?
The amount of degrees a pool heater raises temperature will vary depending on several factors, such as the outdoor temperature, the size of the pool, and the type of pool heater used. A large pool in a cold climate may require much more energy to increase the temperature than a smaller pool in a warmer climate.
A gas or propane heater typically raises the pool temperature up to 20 degrees Fahrenheit. A heat pump, which runs on electricity, may raise the temperature up to 10 or 12 degrees Fahrenheit. Solar pool heaters are also available, though these may not provide as much of a temperature boost as the other types of pool heaters.
