Product Brand: Coates
Coates Spa Heaters are intended for use on spas or hot tubs having a forced water circulation system. The stainless steel tank is designed to optimize heat transfer by directing the water flow over the incoloy elements efficiently.
The built in flow switch prevents operation when there is no water flow and allows operation at flow rates between 15 GPM to 80 GPM. Higher flow may damage the heater. An external bypass should be installed to limit the flow to within this range.

- Piping connections 1-1/2" x 2" union connections for PVC pipe
