When it is going to be below freezing I just make sure my fresh water tank is full and unhook everything outside and use my internal water. My filter is inside all the time so all I have to bring in is my pressure regulator. I always leave the hose outside slightly low on one end so it drains. That way I can hook back up to refill the tank when necessary even when it is below freezing. I can't see the expense of a heated fresh water hose when the faucet is going to freeze if it is cold enough. Not worth the headache. That is why we have fresh water tanks. IMHO
