Having a swimming pool during the hot summer months is an amazing thing. The thing about swimming pools is that even when it’s hot, jumping in a cold pool can be a huge shock. The great thing about pools is that pool heaters and heat pumps exist. They’re very useful, but they won’t heat your pool up immediately. You still have to wait a period of time until all of your pool is heated.
Overall, pool heaters are becoming a necessity for everyone who owns a pool because they add such comfort to your swimming experience. While without them you can only use your pool when it’s hot, you can continue using your pool well into fall and even during spring when it’s a little colder. Here’s more information on how long it will take to heat your pool.
How Long Does It Take To Heat A Pool
There isn’t a straightforward answer to this question. If you have a 10,000 gallon pool, then a 116 BTU heater will raise the temperature of your 1.4 degrees per hour. If you’re trying to raise your pool around 10 degrees, you can expect it to take 11 to 12 hours to heat up. If you have a larger pool than that, you’ll have to wait a little longer. You can use that average as an estimate, however there are factors to do impact how quickly your pool will heat.
Important: As a homeowner, realizing that you need to waste another Saturday waiting for the landlord or handyman to come over to fix another damaged appliance is frustrating. It shouldn't feel like the norm to constantly have damaged appliances and systems in your home since it can come to a huge cost at the end of each year.
The Home Improvement Solutions eBook covers everything you need to do in your home when it comes to maintenance and improvement so you can avoid wasting another weekend waiting for someone to come to your rescue.
The first factor that you have to consider is the size of your heat pump or heater. These are sized according to their British thermal unit per hour. 1 BTU, or British thermal unit, raises a pound of water by 1 degrees Fahrenheit what is 0.6 degrees C. One gallon of water is equal to 8.34 pounds of water, so keep that in mind if you’re used to measurements in pounds rather than gallons. You want to purchase a heat pump or heater that’s the proper size so you can properly heat your pool.
This may seem obvious, but the size of your swimming pool also matters. Keep in mind that larger swimming pools require longer heating times. If you have a small swimming pool, not only will you need a smaller heating pump or heater, but you also have to wait a short amount of time.
Another factor that’s important is the air temperature. Air source heat pumps need the air temperature because they use the heat to warm your swimming pool. Heat pumps operate efficiently and temperatures that are over 50 degrees Fahrenheit or 10 degrees Celsius. If the temperature is lower than that, they can’t efficiently pull heat from the air so they’ll need a lot more time to warm your swimming pool.
Also, the current and desired water temperatures matter. If there is a large difference between the water temperature that you want and the current water temperature you have, then you’ll have to wait longer. For example increasing your water temperature by 10 degrees fahrenheit is a shorter amount of time then increasing your water by 20 degrees fahrenheit.
Lastly, it also matters if you use a solar blanket (view on Amazon). Solar blankets reduce required heating time because 75% of the swimming pools Heat can be lost because of evaporation. The solar blanket can trap the heat in the water by decreasing evaporation. It is a barrier between the air and your pool so it’s very useful.
Now that you know how long it might take to heat up your pool, you can decide if you want a heater or a pump if you don’t already have one.
Do You Get a Heater or Pump
Both of these choices heat your pool but they heat them in different ways.
Heat pumps don’t create their own heat. They use the heat from the air to heat your pool water. If you live in a cold environment, this isn’t a great choice for you. Heat pumps need temperatures above 50° Fahrenheit and if you live in a place where the temperatures are constantly below that, then this isn’t The best way to heat your pool. You should understand the average temperature in your area during cooler months before you get a heat pump.
Pool heaters can we place the three different categories based on how they draw their power. Before you get a pool heater, we should also consider the average temperature during the coldest months of your location. Electric pool heaters are a great solution for you if you were to extend your swimming season. This option works the same way as the heat pump, so if you live in a cold environment, this isn’t great for you.
Solar pool heaters use the sun’s heat to heat your pool. It uses solar thermal panels installed on your roof or on the ground to get its power. It harnesses the heat from the sun to heat the thermal panels which then heat the pool water. The water is pumped from the pool into the solar panels so they can be warmed. This is a great option for you if you live in a sunny area, but if it’s during the hotter months there are often overcast skies, you should consider a different pool heater.
The last pool heater is a natural gas heater. It will heat your pool in a few hours compared to some of the other heating options. It burns gas in a combustion chamber and then runs the cold pool water through the piping in the chamber. The warm water is then returned to your pool and the process will continue until your pool reaches the desired temperature.
Overall, you should choose the heating option that best fits your environment. You have to consider the weather and the likelihood of overcast skies before you choose an option. If you live in a colder and overcast area, then your best choice would be a natural gas heater.
How to Pick Pool Heater Size
Buying a pool heater that’s too small can also increase the length of time it takes to heat your pool. Before you buy a heater, you should know that the bigger the heater is, the better it will be. You should consider how big your pool is and whether you’re heating up a pool and spa combination. If you’re getting a pool and spa combination, that’s a lot of water so you need the largest BTU size available. There is a way to calculate the heater that you need.
1. Calculate the surface area of your pool. Do this by multiplying the pool length with a pool with.
2. Divide the surface area of your pool by 3. This is the minimal BTU size recommended for that surface area. You might need to go a little higher depending on the environmental factors and how quickly you want your pool to heat.
3. Consider what variables you might have to deal with before you get the smallest size. Do you have a pool cover? If so then the smallest size might be okay because it will stop heat loss. If you don’t have a pool cover, you might need a heater with a higher BTU. You might want to consider investing in a solar blanket before you pay for a larger heater.
Once you’ve done all these things, you can choose the heater that you need the proper BTUs. Keep in mind that the smaller choice might be cheaper but in the long run it may cost you more time and money.
Heat Pump Efficiency
Heat pump efficiency also plays a big role in how quickly your pool will heat. The energy efficiency of your heat pump is measured by Coefficient of Performance. The higher the COP is, the more efficient the heat pump will be. There isn’t a standard test for measuring it so you can’t really compare the COP of different models unless you know the manufacturers use the same test for each model. Usually manufacturers measure this by testing a heat pump pool heater with an outdoor temperature of 80 degrees Fahrenheit in a pool temperature of 80 degrees Fahrenheit. The COP ranges from 3.0 to 7.0. This means for every unit of electricity used it takes 3 to 7 units of heat out of the heat pump.
Keep this in mind before you get a heat pump to heat your pool. You want a heat pump that is very efficient so that you can heat your pool using the minimum amount of energy, which will save you money on your energy bill.
Now that you know a little bit more about heating your pool, you can make the best choice about whether you want to heat pump or heater. If you already have both of those, then you can use the calculation given to know how long it’ll take you to heat your pool. Before you make any big purchases, consider getting a solar blanket to couple that with your heating tool. Now you can extend your swimming times during the year to fall and spring when you wouldn’t have been able to use it before.
