400,000 BTU Pool Heaters

A 400,000 BTU pool heater is a high-powered heating unit capable of warming large pools efficiently and quickly. With a capacity to deliver 400,000 British Thermal Units (BTUs) per hour, it is ideal for pools ranging from 20,000 to 40,000 gallons, depending on factors like climate, pool use, and desired temperature. These heaters are commonly used in residential and commercial settings for medium to large in-ground pools, and they can even accommodate pools with attached spas or high-use applications. This BTU rating provides a fast heat-up time and maintains stable temperatures, making it suitable for regions with cooler climates or for pool owners who want reliable heating regardless of season.
