Product details

The Coates 34845PHS is a PHS Series electric pool and spa heater rated 45 kW at 480V three phase, with a digital thermostat, a built-in flow switch and an all stainless steel tank.

What it does

Incoloy heating elements warm the water as it passes through the stainless steel tank. The built-in flow switch prevents the heater from operating when there is no water flow and allows operation at flow rates between 20 GPM and 80 GPM. The 36 to 57 kW PHS heaters add a digital thermostat for more precise control of pool water temperature, along with a manual reset high temperature limit.

Features

The heater has heavy duty contactors and element, flow and high temperature on lights. Element fusing is included on units rated over 48 amps, and this model is rated 55 amps. Connections are 2 in. male NPT. The cabinet measures 28 in. long by 15 in. wide by 15 in. high, and the heater is UL Listed for indoor and outdoor installation. It can be used for residential or commercial applications.

Before you order

This model needs a 480V three phase supply that can carry 55 amps. Coates heaters are not recommended for use with salt chlorinators. For lower voltage or single phase supplies, Coates builds other models in the CE and PHS lines.
