Gas Pool & Spa Heaters

Gas heaters are the best for heating pools or spas up quickly as they use direct and constant heat from a flame, either through natural gas or LPG tanks. A gas heater is an ideal choice for anyone who uses their pool and/or spa sporadically throughout the year and only wants to heat it occasionally, such as on the weekend or when friends come over.

Gas heaters have been around the pool industry for over 60 years and they come in many shapes and sizes. From 65,000 BTU’s to over a million BTU’s commonly used in commercial properties. The advantage gas heaters have over the other types of heaters is that they heat faster.

Gas Heaters are a great way to quickly heat your water, and allow you to enjoy your pool for months past the end of swimming season! Great for in-ground pools in every type of climate, Gas Heaters are designed to extend your swimming into the early spring and late fall by efficiently heating your water to a comfortable swimming temperature. Gas Heaters run on either propane or natural gas, depending on the model, and are very efficient energy users, running at up to 80-95% efficiency. Purchasing a Gas Heater will give you months of warm water even during cold weather, and help you and your family spend more time in the pool than ever before!
