If you have a second sewer hose, just unhook one and hook up the other, if not, you'll need to bring them in (inside a covered tote) and let them thaw next to the heater. Remember, cold, frozen vinyl hose will crack, so be careful twisting and coiling the hose until it thaws some. The more water you flow through the pipes the more heat you'll get to the frozen sections. A dripping faucet will help prevent a frozen section, but the more water you get past the ice the more heat it will absorb and thaw. (within reason of course).
