Electric Heater, Coates ST Series, 11.0kW, 240V, 1 Phase

Coates Spa Heaters are intended for use on spas or hot tubs having a forced water circulation system.

The water flow through the heater should be at least 15 GPM but should not exceed 80 GPM. Higher flow may damage the heater. An external bypass should be installed to limit the flow to within this range.
