When selecting a gas pool heater, there are three things you should consider:
- Monthly cost and annual maintenance
The trained professionals at Aqua Science will work with you to determine the proper size gas heater for your pool and desired swim season. Many factors help determine the size heater your pool will need. Considerations include the time you’re willing to wait for a heated pool, the surface area of the pool and the difference between the pool and outdoor air temperatures. Other factors also affect the heating load for outdoor pools, such as wind exposure, humidity levels, and cool night temperatures.
There are several calculations that go into selecting the right heater. First, you must determine the desired temperature rise per hour. Our product specialists do this through the following calculations:
Desired water temperature – average air temperature = required temperature rise / required hours to heat to desired water temp = required temperature rise per hour
After we’ve calculated the temperature rise per hour, we review the size of the pool. Gas heater sizes are determined by the amount of BTU’s generated (BTU’s are defined as the amount of heat required to raise the temperature of one pound of water by one-degree Fahrenheit). The chart below determines what size heater you should consider.
Efficiency & Cost:
Heating technologies have advanced greatly, and have produced heating units that are the most efficient we’ve seen in a decade. Today’s gas heaters will heat a pool five to seven times faster than an electric heat pump or solar panels. In addition, gas heaters are generally less expensive at the time of purchase and installation than solar heating or heat pumps.
While gas heaters are efficient at heating the water quickly, the cost of natural gas or propane comes at a price. Rising costs of natural gas can influence some homeowners to look at other heating solutions, especially when it can cost a homeowner several hundred dollars each month to keep their pool heated.
No matter what heater you choose, make sure you use a solar blanket to cover your pool when it isn’t in use. The use of thermal blankets will help retain the heat, reduces water loss from evaporation, and reduces the amount of chemicals you need to add to you pool.
