So we have shut down the hot tub for the year, and miss it. The reason for the shut down is fear that the heat exchanger coils, and water circulating pump will burst when they freeze. One cure I have thought of is to put a timer on the pump that will pump warm water from the tub through the coils for lets say 5 minutes per hour every hour. That should be sufficient until Nov when we head for Mexico. Does anyone know of such a 120Volt timer?
