Filling a tub in FREEZING temp

[A Rai]

Hi there,

I am going to be filling my tub today and it is -35 degrees CELSIUS where I live.

I was advised that the pump can have a little bit of water freeze up in front of the impellar to prevent it from spinning. I was advised to put a space heater inside of the cabinet, but I feel this is a fire hazard??

Can someone please chime in on this.

if your dealer doesn't have weekend emergency services I highly advise against filling a spa on the weekend in those temps, but if you need too then yes a space heater can come in handy to thaw any potential small amounts of ice out of the pumps

Use small (750/1500watt) thermostatically controlled space heaters inside the cabinet all the time and leave them inside for days even weeks if needed. I bring them on service calls and place them beside me when it gets really cold to warm my hands and work area.

The space heater is a great idea.  If you want to be sure the impellers are free, there is typically a spot on the back of the pump motor where you can stick a screwdriver or use a wrench to turn the impeller.  It should turn very easily.  If there is any resistance, it is probably still frozen.  If you have a circulation pump that spins freely, or a pump that runs the heater that spins freely, you can unplug the other pumps and only have the heater pump work.  That will at least heat the water and work on thawing the other pump(s).
