I bought a good heavy duty water hose (drinking water safe) laid heat tape on it, then used electrical tape every 6in to secure to hose, then put that round foam pipe insulation over that and duct taped it end to end. Be careful to leave the temp sensor exposed with the black little button touching the hose. We have been below zero here with the wind chills and has worked fine, with no frozen hose.
Or as previously stated you can buy a premade heated hose from many camping supply stores that are guaranteed down to -40 degrees.
