Airbnb, how to keep pipes from freezing during winter?

[Justin Wood]

Need suggestions on how to keep my pipes from freezing. Yes, I have hose covers. But house does not have central heat. It has wall natural gas heaters. I feel it is a safety hazard to leave them on for a week at a time with no one there. Below is the link of what types of heaters they are. But if I don't have a heat source, the house will freeze and the pipes with it. What would you do? I also attached a link to my listing. Any suggestions are appreciated.
