How fast can pool heater heat my pool?

How do you figure out the size of pool heater you need to heat a 14 x 29 10000 gallon in ground vinyl lined pool?

• Answer:

  The size of heater really depends on how fast you want to heat the pool. A bigger heater isn't going to cost more money because it's burning more gas. It is per minute but it's also heating more water in that minute. The standard for that size pool is usually around 200-250K BTU but you can go bigger if you want to heat faster, it will do the job quicker and thus run for a shorter period of time. You should also look at the heaters efficiency, there are a few different ranges and the more efficient units will be more money but will also do the job faster, or with less BTU's.
