Swimming Pool Heater vs Heat Pumps
You might be wondering, what’s the difference between swimming pool heaters and heat pumps? Well, quite a lot actually! Swimming pool heaters use either gas (natural or propane) or electricity to heat the water before returning it back into the pool. Heat pumps, on the other hand, use ambient air surrounding the unit to heat your pool water. There are benefits to both pool heaters and heat pumps, and the right choice for you depends upon your preferences. Electric and gas pool heaters heat your pool water quickly, while offering lower upfront costs. They are also easy to install. When compared to heat pumps, swimming pool heaters typically produce higher utility costs. Heat pumps are becoming a popular option for pool owners thanks to their energy efficiency which translates into cost savings for the pool owner. While they are easy to install, heat pumps work best for mild climates and are seen as ineffective in climates below 50° F. Upfront, you can expect to pay more for a heat pump than a swimming pool heater.
 
Gas vs. Electric Pool & Spa Heaters
Given their low operational costs, easy install and speedy water warming capabilities, gas heaters are the more popular choice for pool owners. You’ll find that our Raypak pool and spa heaters offer great commercial and residential pool heating options. Electric pool heaters are more commonly used for above ground pools and spas, or for owners who do not have a gas line or propane available. For the best electric pool heaters in the industry be sure to check out our selection of Coates, Raypak and Hayward pool heaters.
