I am sure you won't have any issues at all. I actually like to have a few just in case of the unplanned outages. It might be worth finding some in the future just in case you need them anyway they are not very expensive and I have a large tall tub I use if needed I can bag all my snakes and place them into a single tub with a heat source to hold the ambient temps in the 80ºs so they can weather out a outage in safety. You are well prepared but the unexpected ones can catch you with your pants down if you don't plan ahead. I actually tried my system out (no snakes just bags to check the temps and efficiency. )
