Hey, I have a coast spa I believe its a 2001. Anyways, we always have it running up at our cottage during the sumer and fall months (I live in Ontario by the way) but we would like to use it during the winter. We usually go up their and snowmobile on the weekends during Jan-March. And we always thought it would be great to come back after a day on the snowmobile trails and soak in the tub! The problem is, we are not there during the week and its a 2 and a half hour drive up from where we live should something go wrong. During the summer, theres has been numerous times where the power goes out at the cottage and the breaker for the tub gets flipped and we have to reset it when we come up. So my question I guess, is thier any possible way to run the hot tub up their, or is the risk not worth it? also, do they make some product that you can buy that will retain the heat necessary in the lines and tub in case of power outage for days? I know during some nights up their it can get down to -25,-30.... Any thoughts or suggestions would be great, Thanks!
