Coates Pool Heaters

Coates swimming pool and spa/hot tub heaters has been the brand to trust since the 1940s. They’re known for quality and reliability in all of the products they make. They make pool and spa heaters from 1.5kW all of the way up to 57kW and most can be purchased in either single phase or three phase models. For larger commercial applications, Coates also makes heaters up to 300kW. When a pool is in frequent use, a pool heater to make up heat loss may be all that is needed.

Available Pool and Spa Heaters:

ILS Series Available in 1.5kW and 5.5kW models.

These are both compact and efficient while being ideal for residential spas under 400 gallons. These in-line spa heaters come with stainless steel tanks and replaceable Titanium elements

ST Series Available in 5.5kW and 11kW models.

These heaters are for residential spas between 250 and 600 gallons. They have a flow switch that’s built-in that prevents heater operation when there is no flowing water. During normal operations the heater can run between 15GPM and 80GPM. To optimize heat transfer the stainless-steel tank directs water flow efficiently over the heating elements.

CE Series Available in 12kW and 18kW models.

Perfect for large spas or smaller residential pools, they feature a flow switch that prevents operation when there is no water flow. Also available in single phase and three phase configurations. A stainless-steel tank that’s corrosion resistant and built for a long life is also included.

CPH Series Available in 24kW and 30kW models.

Great to be used with residential and small commercial pools. Features the same great abilities of the 12-18kw heaters and include a digital thermostat to get that precise control of the pool water temperature that you’re looking for.

PHS Series Available in 36kW and 57kW models.

Ideal for large pools and cold weather applications. The Coates 36-57kw heaters include a digital thermostat to control the pool water temperature more accurately. Also included are all of the same features as the 12-18kw heaters. These commercial heaters are designed for high capacity installs and incorporate features into their designs that increase service life as well as dependability, and provide ease of servicing. All electrical components are easily accessible under the conveniently hinged cover. Terminal blocks are provided for simplified power supply wiring. Manufactured with corrosion resistant stainless-steel tank surfaces and low watt density elements which are mounted on four-bolt stainless steel flanges set up the heater for a trouble-free service life.

Coates Salt Water Heaters

Coates also manufactures salt water heaters for use with salt water chlorine generator sanitizing systems. These heaters have increased corrosion resistance with Copper-Nickel tanks and Titanium heating elements. Coates offers corrosion resistance up to 3500ppm.
