Pool Heaters

Cold weather is inevitable, but don't let that stop you from enjoying your pool. Turn your swimming pool into a warm, inviting haven with a pool heater. This smart investment will extend your swim season well into the colder months, and in some cases carry you through the entire season. Now you can enjoy your pool in the evenings despite an unexpected chill. Gas and propane pool heaters are some of the most popular types of heaters to warm your pool. They work fast and maintain a consistent water temperature. These heaters work on cloudy days or at night, unlike solar heaters. The electric swimming heaters at Pool Express are available in two main types: a heat pump and an electric heater. A heat pump is typically used to heat larger pools, while an electric heater is used for smaller pools, spas and above ground pools of 5,000 gallons or less. Heat pump electric heaters are known to lower energy costs and are popular for this reason.
