During cold seasons like winters, swimming pools are always ice cold and most of them go under winterization, which means they are closed for the whole periods of the winter and fall.
However, People who like swimming and warm baths do not like Winterization, people want to enjoy swimming in any season anytime as they want. With pool heaters, People can enjoy your winters and any cold weather days in a spa without worrying about ice cold water.
Choosing a heaters generally starts from two aspects：
1.There are 3 main types of spa heaters; gas heaters, heat pumps, and solar heaters. Before choosing, you have to know the working principle and be sure it is the best option in terms of size, how convenient the heater is and the cost factor.
2.Generally, cost, size, conveniency and pool location are the main things to consider for chooing a pool heater: Size of your spa will determine the size of the pool heater that you buy, while operating cost, conveniency, and location will determine the type of pool heater that you choose between gas, pump and solar heaters.
When considering cost in choosing the best pool heater for your spa however, it is important to know that cost difference will not be very dramatic and in the long run operating cost should just be around the same range.
A significant difference in operating cost however will depend more on how well or bad you operate and maintain your spa whether it uses a gas, heat pump or solar heater.
For example, spa maintenance measures such as covering your spa with a pool cover that prevents heat from evaporating when pool or spa is not in use will reduce operating cost of any pool heater.
When it comes to your location or state, the best pool heater for your region may be determined by how cold or warm your state or region is during different seasons and sometimes electric rates in your state being some states have exorbitantly higher rates.
Generally, a little warmer regions like Texas may require a heat pump because it will be economical in using electricity to maintain the ideal water temperature, rather than using a gas heater that is best for extremely cold regions like Philadelphia that requires heavy and instant water heating.
Generally, Heat pumps always work best in less colder regions: In colder regions, heat pump will overwork, use more electric units and have some difficulty heating and maintaining your spa water at some higher temperatures.
