Remember that your attic or garage temperature will always be 15 to 20 degrees warmer than the outside temperature. We recommend a thermometer in your garage or attic that you can easily monitor.
Also, if the outside temperature outside is around 20 degrees, you will need to turn on a hot water faucet located at the farthest sink from the tankless unit. Run a stream of hot water that looks like the picture to the right. This only uses .7 GPM of water. This will keep the unit running at its lowest level, keeping the tankless unit and its piping from freezing.
You should also drip the cold water faucet.
Both the filter blanket wrap and hot water running are recommended.
If the electric power is out, you use the same procedure.
Remember, the water entering your home is 55 degrees, and moving water can not freeze.
