This will give the temperature rise needed. d) Calculate the pool surface area in square feet. e) Use the following formula provided by the U.S. Department of Energy:
Pool surface area x Temperature Rise x 12 = the Btu/ hour output required
Based on this information, you can decide which heater is appropriate for your pools.
Additional benefits to heater upgrades
In addition to energy and money savings, there are a few additional reasons to upgrade to a new heater: 1. Lower Emissions: Today’s heaters are cleaner burning heaters (or Low NOx) heaters which have minimal emissions.
In most of California, as well as Texas, these are required and have a regulated emission standard.
More states are sure to follow in the coming years.
2. Easier Maintenance: Newer heaters are much easier to install and maintain, because they are designed to be more “plug and play,” including such features as sealed combustion, reducing the chance for internal issues to occur such as condensation.
Modern units are also ultra-quiet, have faster heat-up times, and are easy to install both indoors and out.
3. Sealed Combustion: Many new heaters today have sealed combustion units. These are safer because: a) Pool heaters installed indoors are frequently located next to stored chemicals, and sealed combustion presents much less of a fire hazard. b) Adequate combustion air is guaranteed when outside air is ducted with a sealed combustion unit.
Conclusion
Armed with all such facts, pool professionals may find it easy to sell and upgrade customers to a newer, more efficient heater that will immediately reduce the pool’s energy bills. With so many families at home and hoping to extend their swim season, updating the heater will surely make customers happy, especially when they see how it lowers their monthly bills.
