How to Choose the Right Size Heater for Your Commercial Pool or Spa
The Stanley Louis Company can calculate the correct size of pool heater for your specific needs
Choosing a correctly sized heater for your pool or spa is important for any property owner, but especially for a commercial property owner.
Because your pool is considered a valuable amenity by your residents or guests, you can’t afford to choose an undersized pool heater. This would irritate your clients with chilly water or long waits for the water to reach the desired temperature. But you also don’t want to choose an oversized pool heater that will cost more than necessary to install and run, as this will eat away at your business profits.
Fortunately, you can turn to The Stanley Louis Company for help selecting the correct size of pool or spa heater for your specific needs. We’ve been working closely with commercial hot water equipment since 1981 and we have the experience required to steer you to the correct decision.
Here are some of the most important factors to be considered:
Pool Size: Obviously, a larger pool is going to require more energy to keep at your desired temperature. But, it is important to bear in mind that both the volume of the pool and the surface area will have an impact on the amount of heat that is needed. Most of a pool’s heat is lost through the surface, meaning that a long, shallow pool will actually be harder to keep heated than a small, deep pool that has the same volume but a smaller surface area. But in the case of a spa, your concern isn’t so much maintaining heat as generating heat quickly. This makes volume your primary size concern for a spa.
In any case, we can accurately calculate the surface area and volume of your pool and make sure you’re basing your pool heater purchasing decision on the right variables.
Temperature Differential: The difference between your desired water temperature and the ambient temperature—aka the temperature differential—is also going to impact your pool heater size. Typically, you will calculate the temperature differential based a water temperature of 78 to 82°F for a pool and 104°F for a spa, and the average ambient air temperature during the coldest part of the season when the pool or spa will be used. The greater the temperature differential, the bigger and more powerful your pool heater must be.
Heat-Up Time: One final factor that can influence the size of your pool heater is how long you are willing to wait for the water to heat. Most pool heaters assume a 24 hour wait time, which is sufficient for a pool that will be used daily and therefore must be kept warm at all times. Spa heaters are more powerful and can heat the water faster.
