Pool Heater Btu Calculator. This means that it would take 207,500 btu's per hour in order to raise this 20,000 gallon pool from 50 degrees up to 80 degrees in a 24 hour period of time. Based that information, the calculator will recommend an amount of hours it will take to heat the.
2019 Best Inground Pool Heater for the Money? from www.chainsawjournal.com
Using our example above, we can now calculate the btu needed for our pool: Divide your surface area by 3 (surface area/ 3) once you determine your pool’s surface area, divide it by three. We will show you that later in our sample pool heater selection.
Now, Divide This Btu Total By 24 (Hours) To Determine The Btu's / Hour Required To Heat The Water:
Usually, if you have a pool and spa combination, i recommend purchasing 30% higher btu, for example going from a 300k to a 400k. Determine the desired temperature of water in °f. Btu is often used as a point of reference for comparing.
Current Pool Heaters Are 85% To 90% Efficient.
4,980,000 / 24 = 207,500 btu's per hour. The pool heater calculator is more applicable in sizing a gas or propane pool heater. Please note, after putting in your measurements, our pool heater calculator will ask you to put in the current temperature of your pool and the desired temperature.
The British Thermal Unit, Or Btu, Is An Energy Unit.
Heat loss in a swimming pool adds to the heating required. Heating up a pool versus a pool/spa combination requires less btu power. How to calculate heat loss.
* Therefore, Any Under Or Over Sizing Of The Heater For Your Pool Heating Requirements Is Not The Responsibility Of Aussie Pool Heating.
Considering the fact that there are medium to large pool sizes in the houses these days, a pool heater with a btu in the range of 200k to 350k respectively would be good enough. Using our example above, we can now calculate the btu needed for our pool: Size at 5 btu’s per gallon or 1.3 to 1.5 btu’s per litre of water.
It Is Approximately The Energy Needed To Heat One Pound Of Water By 1 Degree Fahrenheit.
If you want to perform the calculations for. Therefore, pools located in areas with higher average wind speeds at the pool surface, lower humidity, and cool nights will require a larger heater. The key question, as you can see, is in which climate zone you live.
