Product details

The Coates 1.5ILS is an in-line electric spa heater rated 1.5 kW at 120V and 12 amps, with a built-in pressure switch, a stainless steel tank and 1-1/2 x 2 in. union connections.

What it does

The stainless steel tank is designed to optimize heat transfer by directing the water flow over the Incoloy elements. The built-in pressure switch prevents operation when there is no water flow and allows operation at flow rates between 15 GPM and 80 GPM. A close differential thermostat controls temperature, and a manual reset high temperature limit adds protection.

Features

Coates in-line spa heaters have replaceable Incoloy elements and a control box with a powder coat finish, plus an element on light. The unions connect to PVC pipe in 1-1/2 or 2 in. sizes. The heater is 15 in. long without the unions and 19-1/2 in. with them, with a control box of 12 in. by 6 in. by 6 in. It is UL Listed for indoor installation.

Before you order

This unit does not come with a pigtail or plug and needs to be hardwired. Coates heaters are not recommended for use with salt chlorinators. The 6ILS is the 5.5 kW, 240V model in the same in-line series.
