Coates swimming pool and spa/hot tub heaters are well known for the highest in quality and reliability, and have been trusted by pool and spa owners since the 1940s. Offering a wide range in power, from just 1.5kW all of the way up to 57kW. Coates has a model to suit every application. Additionally, most heaters can be purchased as either single or three-phase, depending on your specific need. Also, for larger commercial applications, Coates also manufactures heaters up to 300kW.
