So I'm new to tankless WH in an RV. When you winterize do you store them with antifreeze in the lines or can you effectively drain and blow them out? When I bought the unit during the PDI I was told to always put antifreeze in it because there is no way to get all the water out. I want to do what's going to protect my heater best but would like to avoid storing antifreeze it in.
Hummmmmmm. No information about the specific unit you are talking about or where/how/what it's installed in. I would suggest you read the manual that came with the tankless WH along with the general information in the manual that came with your RV.
