Hi everyone, I live in Toronto, Canada (hot summers, freaking cold winters). I have a hot tub that's not being used by my tenant. As such, he also doesn't want to pay for the electricity. I've heard that I can't leave the hot tub empty, but if I keep it full and not use the pumps, then the water doesn't get circulated. My original idea was to buy a small external pump that I place inside the hot tub so that the water is moving. But the tiny pump is always breaking, and it barely moves any water.
So I'm wondering how you guys deal with a spa that you might not use for a year or so.
Thanks
