Now you can enjoy warm water no matter the time of day or time of year with a propane pool heater. These heaters essentially work the same as a natural gas setup, but will require a propane tank to operate properly. The propane pool heaters at Pool Express have made great strides in energy efficiency. They use the latest technology to quickly heat your pool, so you don’t have to wait long to take a late night or off-season dive. View the selection of low-nitrogen oxide (low NOx) models, which mean they are designed to produce fewer emissions than traditional propane heaters of the past.Heaters that run off propane are ideal for pool owners who live in colder climates and need the water maintained at a specific temperature. This is because they don’t depend on the weather or time of day to operate, unlike solar heaters. And their heating speed is much quicker than traditional electric heaters. Imagine taking a swim in a warm, inviting pool in October! Propane heaters can help you get there.
