This Coates ILS In-Line 1.5kW electric spa heater is compact and efficient and features a stainless steel tank and replaceable titanium elements. The ILS spa heater is perfect for residential spas less than 400 gallons. The stainless steel tank is designed to optimize heat transfer by directing the water flow over the elements efficiently. It has a built-in pressure switch which prevents operation when there is no water flow.

Very compact in size, this electric spa heater is rated to produce 5,120 BTU's per hour and connects with either 1.5 inch or 2 inch connections. This heater requires a standard 120 volt electrical connection but must be hard wired and does not come with a plug.
